Under and over frequency supervision of single or three phase systems.
The unit BF1 is equipped with an independent over (f>) and under frequency supervision (f<) with seperate
adjustable pickup values and trip delays. The measured frequency is continuously compared with the set reference values.
For frequency supervision the cycle duration is evaluated and so measuring is virtually independent on harmonics. To avoid tripping during normal operation due to interference voltages, a fixed measuring repetition is used.
