Description

KCFV54x Series KCFV54x - THREE PHASE - 4-WIRE FREQUENCY AND VOLTAGE GUARD Under and Over Voltage and Frequency Protection Adjustable Voltage and Frequency Deviation Set points "Pathfinder" function Optional very fast analogue output (<50mS), (F-versions) Optional slave DIN96 Indicator Description KCFV54x is for use on three phase, four wire systems. KCFV54x provides precision monitoring of frequency and line voltage on any generator system. When trip delays are set to zero (0,1sec) operation corresponds with G59 requirements. True RMS measurement not affected by heavily distorted waveforms provides highest up precision (1.0%) protection. Less than 50mS short circuit detection. R1 (under & over frequency) and R2 (under & over voltage) activates when set level is exceeded and time delay has elapsed. R3 activates when R1 or R2 is activated and can be used as a common alarm
