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 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.

The voltage on modern distribution circuits is becoming increasing difficult to manage. New distributed energy resources, such as solar, combined with the growth of sophisticated loads creates voltage challenges on distribution network systems. Existing voltage control devices cannot maintain a consistent voltage profile, especially when trying to manage the intermittency of these resources and loads.

The voltage on modern distribution circuits is becoming increasing difficult to manage. New distributed energy resources, such as solar, combined with the growth of sophisticated loads creates voltage challenges on distribution network systems. GE Vernova's robust and reliable Voltage Regulators help to address these challenges.
GE Vernova's family of voltage regulator products, along with their dedicated controllers, supports both substation and pole-mounted applications as illustrated below.
The Pole-mount/platform mount Voltage Regulator (VR-PM) is GE Vernova's premium product for voltage control outside the substation and has established the benchmark in the industry for robust design and operational reliability. It is the only voltage regulator on the market that is guaranteed to support 2 million switch operations and adheres to the latest IEEE C57.15-2009 and C57.131 standards of 40x rated short circuit current.
GE Vernova's Substation Voltage Regulator (VR-SS) is a single phase voltage regulator that is intended to support this type of application within a substation. The advantages of single phase units are twofold; they provide the ability to manage each phase independently in the event of unbalanced loads, and they provide redundancy when compared to an individual 3-phase unit.
GE Vernova's Voltage Regulation solutions integrate seamlessly into utility optimization and control strategies for voltage regulation, and is comprised of the following components:
