    7SG11 Argus 8 Description of Operation sequence calculations. The ZPS calculation, which is used in the neutral voltage displacement (NVD) function also benefits from excellent inherent 3 harmonic rejection. All relays are fully calibrated during manufacture using accurate voltage source equipment. Calibration coefficients are stored in EEPROM and are used by the processor to compensate for any inaccuracies in the input stage, which have been introduced by the analogue circuits.
