 Effective analog low pass filter for suppressing harmonics when measuring frequency, df/dt

 and vector surge.

 Digital filtering of the measured values by using discrete Fourier analysis to suppress

 higher harmonics and d.c. components induced by faults or system operations.

 Integrated functions for voltage, frequency, df/dt and vector surge in one device.

 Voltage supervision each with two step under-/and overvoltage detection.

 Frequency supervision with three step under-/or over frequency (user setting).

 Completely independent time settings for voltage and frequency supervision.

 User configurable vector surge measurement 1-of-3 or 3-of-3.

 Adjustable voltage threshold value for the blocking of frequency-, df/dt or vector surge
