High-speed, draw-out transformer protection and management
Manufacturing for 745 has been discontinued. As an alternative, please refer to the 845 relay
The 745 Transformer Protection System is a full featured transformer protection relay, suitable for application on small, medium, and large power transformers. The 745 can be applied on two-winding and three-winding transformers, and can be applied on transformers with breaker-and-a-half source terminals. Multiple current and voltage inputs are used to provide primary protection, control and back-up protection of transformers, including current differential, Restricted Ground Fault neutral, and ground overcurrent, over-fluxing, and on-load tap changer. The 745 also has specific features for industrial environments, including a drawout case to limit downtime during maintenance and conformal coating for harsh environments. The 745 also includes analog inputs and outputs, while incorporating advanced features such as transformer loss of life monitoring.
The 745 features advanced metering functions including:
Currents All current inputs feature harmonic level detectors. A sampling rate of 64 times the power cycle allows recovery up to the 21st harmonic. Total Harmonic Distortion (IEEE.519-1986) or Harmonic Derating Factor (as per ANSI/IEEE C57.110-1986) are calculated for each winding and compared against user-adjustable setpoints.
Asset Monitoring745 can monitor, calculate and log hottest-spot temperature, aging factor and lost of life data over a long period. These data combined with economic analysis, allows criteria to be developed regarding the best time at which to replace a power transformer due to load growth, i.e. to minimize the cost without significantly increasing the risk.
Event RecordingThe last 128 events are captured and stored, recording the time, date, cause, and system parameters of each event. This information is easily accessible by computer via communication port or the front panel display.
Tap Position, Ambient Temperature, Analog Transducer-InputThe 745 monitors and displays tap position and ambient temperature. An optional general purpose transducer input allows a user-defined quantity to be monitored and used as part of the protection as defined by FlexLogic™.
Simulation ModeSimulation Mode allows testing the functionality of the relay by simply feeding arbitrary waveform data into the relays simulation buffer for playback as sampled current input signals.
Fault RecordingSystem input signals are sampled at a rate of 64 times the power cycle. Because all the signals are sampled at the same instant in time the magnitude and phase relationship of each can be compared. A combination of 16 pre and post-trigger cycles can be saved.
The 745 incorporates advanced automation features including powerful FlexLogic™ programmable logic, communication, and SCADA capabilities that far surpass what is found in the average line relay. The 745 integrates seamlessly with other relays for complete system protection.
The 745 is equipped with three standard serial communications ports, one RS232 located in the front panel, and two RS485/RS422 in the rear of the relay. One optional Ethernet port is available at the rear of the relay. The front panel port allows easy local computer access. The rear ports provide remote communications or connection to a DCS, SCADA, or PLC. The baud rate of all the ports is variable from 300 to 19,200 bps. The optional Ethernet port can be used to connect the 745 to 10 Mbps Ethernet networks. The 745 supports ModBus® RTU, DNP3.0 Level 2, and ModBus® RTU TCP/IP protocols.
The three serial ports support ModBus® RTU protocol, while either of the two rear ports can be configured to support DNP 3.0 Level 2. The optional Ethernet port supports ModBus® RTU via TCP/IP protocol. The communication system of the 745 is designed to allow simultaneous communication via all ports.
Using Ethernet as the physical media to integrate the 745 to Local or Wide Area Networks, replaces a multipoint wired network (e.g., serial Modbus®), and eliminates expensive leased or dial-up connections, reducing monthly operating costs.
Various user interfaces facilitate operation of the 745.
DisplayA 40 character display allows access to setpoints, actual values, and diagnostic messages generated by a trip or alarm condition. The745 can display 30 user-selected messages during keypad inactivity.
IndicatorsTwenty LEDs indicate relay status, system status, and trip and alarm conditions.
IRIG-B InputThis feature provides time synchronization via standard GPS clock inputs.
The EnerVista™ Suite is an industry-leading set of software programs that simplifies every aspect of using the 745 relay. The EnerVista™ suite provides all the tools to monitor the status of the transformer, maintain the relay, and integrate information measured by the 745 into DCS or SCADA monitoring systems. Convenient COMTRADE and Sequence of Events viewers are an integral part of the745 Setup software included with every 745 relay, to carry out postmortem event analysis to ensure proper protection system operation.

The status of each of these contact are also displayed on LEDs found on the relays front panel.
Eight digital inputs are available for monitoring the status of external contacts, tachometers, or control switches. With these inputs, the relay can identify the status of the associated breakers and receive commands from operational staff such as controlling the output relays, resetting the thermal limits, or triggering a waveform capture.
Twelve RTD inputs allow the 489 to monitor both the generator stator and bearing temperature. A built in voting feature adds additional security by ensuring that two RTDs monitoring the same device both detect the overtemperature condition before tripping the generator offline.
Four analog inputs are available for providing protection and monitoring of generator bearing vibration. The analog inputs are field programmable to measure transducer signals that operator over a range of 0 to 1 mA, 0 to 20 mA, or 4 to 20 mA.
Four analog outputs are available for signaling the value of measured analog quantities to external process control devices such as PLCs. The analog outputs can be ordered to operate over a 4 to 20mA range or a 0 to 1mA range and can be configured to signal a representation of most analog quantities measured by the 489 including currents, voltages, frequency.
The 489 provides advanced communications technologies for remote data and engineering access, making it easy and flexible to use and integrate into new or existing monitoring and control systems.

SUPERBUTE dry-type instrument transformers are engineered and rigorously tested to provide a measurable difference in reliability and durability. Since the very first unit produced in 1955, SUPERBUTE instrument transformers have provided utilities with a number of benefits for enhanced safety and a lower total cost of ownership. SUPERBUTE is designed to meet IEEE C57.13 standards and ANSI standard mounting provisions, terminals, and construction.
Field studies and accelerated life testing has shown an average operating life of more than 40 years, with reliability measures 3 times better than published industry benchmarks
Internal insulation is made from epoxy resin which is encapsulated in tough, elastic butyl rubber, dampening and minimizing the impact of high energy events
Unique dry-type construction ends oil leakage problems, eliminates breakage and vandalism issues, and does not support combustion
The dry-type design eliminates the need for oil testing or filtering and allows for a compact design which facilitates mounting flexibility for more economical installations such as on existing steel structures, inside a cabinet, or on a pole
Extensive vertical integration within the factory allows for standard lead times of 4-6 weeks, nearly half the industry average
The outer shell of SUPERBUTE transformers are made with GE Vernova’s proprietary formula of butyl rubber, which is called HY-BUTE 60. This material adds the following timeless advantages over epoxy resins or porcelains designs:
Epoxy takes the place of oil as the internal insulation and winding impregnation. The advantage of this design includes:
SUPERBUTE instrument transformers are designed for quality and reliability with features engineered to withstand high voltage stresses and extreme environmental conditions, while delivering the highest accuracies possible, all within a compact design. The result is a reliable, long-lasting, easy to handle design that ultimately lowers total cost of ownership.
Originally patented by GE Vernova, lattice-type windings have precise controlled positioning and distribution of each turn to reduce maximum voltage stress within the winding. This unique design also minimizes the possibility of partial discharges within the winding. The coil configuration, and the outer electrostatic shields distribute steep voltage fronts across the coil to reduce concentration of stress.
A unique multi-gap type primary by-pass on current transformers 600 amps and below protects windings during line disturbances or steep current wave fronts. The gaps are factory adjusted to fire at 5000-7500 crest volts, thereby by-passing surge currents up to 100 times rated, which could otherwise result in excessive voltages across the primary winding.
The use of high accuracy instrument transformers with solid-state metering allows for improved billing accuracy and/or the potential to reduce inventory requirements. GE Vernova offers high accuracy and extended range ratings which meet the accuracy needed for these applications. Since introducing the first dry-type high-accuracy transformer solution in 1991, GE Vernova’s high accuracy product line has grown to a portfolio that includes a wide variety of voltage classes up to and including 69 kV.
SUPERBUTE transformers require up to 30% less height and up to 40% less floor space compared to the leading oil-filled designs, and can be mounted in any position. This allows substation design flexibility including mounting on a substation steel structure or a pole.
Even with 30% less height, standard units can be used in environmentally severe conditions and in high altitude (10,000ft) applications. Station class units have creep distances that exceed the requirements for even the next-level voltage class.

This range of polyurethane encapsulated current transformers is designed for 5 to 34.5 kV class applications. Several models may be ordered with or without primary bars to suit customers needs.
Encompass™ Current Transformers from GE Vernova offer electrical utilities piece of mind knowing they’ll have the right CT in stock. Upgrade today and eliminate the need for multiple current ratios, thereby simplifying CT selection.
Encompass wide range CTs are designed for commercial and industrial applications. Encompass CT’s substantially reduce inventory, complexity and improve standardization for meter shop operations, particularly when used with GE Vernova’s kV2c FITZALL™ transformer rated meters.
Encompass and RevenueSense CTs provide flexibility for commercial and industrial applications, indoor or outdoor service and bar-type or window-type configurations.
Traditionally, CT accuracy is tested at:
With GE Vernova Encompass CT’s, the 0.3 accuracy class is extended by changing the test points to:
A rating factor of 4.0 means the Current Transformer meets rated accuracy at up to 4 times the rated primary current. Thus, the output on a 5 Amp CT secondary can be used up to 20 Amps if a rating factor of 4.0 is assigned to the CT (4.0*5A = 20A). This pairs the CT output range and the Meter input range when used with a CL20 transformer rated meter, maximizing the performance potential of the system.
The 4% and 40% test points in combination with a high rating factor of 4.0 means 1 Encompass CT can equal or better the performance of both higher AND lower ratios.
The 500:5 Encompass unit when compared to a 200:5 standard CT has equal to or better test results at all points included even low currents and is available at an equivalent price. This comparison holds true across several other standard CT ratios, meaning one Encompass CT can functionally replace up to eight other standard ratios, allowing for an inventory reduction of up to nearly 90%.
To demonstrate the advantages of upgrading to an Encompass CT, let’s compare a JAK-0W 500:5 Encompass CT to a JAK-0C 200:5 standard CT
Physically, the JAK-0W 500:5 Encompass CT:
Electrically, the accuracy of a JAK-0W 500:5 is equivalent or better than the accuracy of a JAK-0C 200:5 across all test points. This can be looked at two ways:
A 500:5 Encompass CT has ±0.3% accuracy from 200A to 2000A, compared to a standard 200:5 CT which has a ±0.3% accuracy from 200A to only 800A. Both CT’s have ±0.6% accuracy from 20A to 200A.
The 500:5 Encompass CT has equal to or better accuracy rating across the entire 20A to 2000A range. It is important to note that accuracy class only defines the “tolerance of error” allowed in a CT. Actual test results are also an important factor when evaluating CT’s. At a typical burden of B-0.1, the Encompass CT test results slightly outperform a standard CT, even at the lowest test amps. All Encompass test results are well within the IEEE limits.
* Tested Accuracy Class values shown are for illustrative purposes only, and not a guarantee of performance. Actual results may vary, within defined test tolerances.
