CKF-319 TRMS
Phase loss and phase
sequence sensor
The CKF-319 phase loss and phase sequence microprocessor
sensor without neutral wire is designed to protect electric motor
powered from the three-phase network in following cases:
»
voltage loss in at least one phase;
»
voltage drop in at least one phase below 150 V;
»
voltage increase in at least one phase above 280 V;
»
voltage asymmetry between phases above the set value;
» incorrect phase sequence.
The sensor correctly measures the true rms value of the
voltage (TrueRMS), even when the power supply voltage
is (disturbed) distorted.
