DFF Digital Frequency Relay - Legacy
Manufacturing for this product has been discontinued. As an alternative, please refer to the F60, G60 or F650 relays.
The DFF is a digital relay used to supervise the frequency of the power system and provide load shedding capabilities. The DFF is applied directly to a generator to protect against those abnormal conditions that result in frequency fluctuations, and throughout the system to "shed" load in an attempt to regain frequency stability.
Applications
- Load shedding frequency schemes
Protection and Control
- Underfrequency protection
- Under and overvoltage protection
- 33 configurable outputs
- 14 configurable inputs>
Monitoring and Metering
- Event record, last 150 event
- Oscillography, 4 records
- Voltage: 16 samples per cycle
User Interface
- Keypad and LCD display
- 16 configurable LEDs
- Front RS232 port
- Rear RS232, RS485, or fiber optics
- Software provided
