विवरण

• Specifications 1 Comprehensive Source of relay 2 three phase unbalance protection four failure five voltage and over voltag 3 phase delivery control relay (Phase series relay) is designed to monitor three phase supplies and to guard motors and other loads against the faults listed under · Monitoring of rotational path of phases · Detection of complete failure of one or more of the stages · Undervoltage detection (-10%) · Overvoltage detection (+10%) · Detection of section asymmetry (imbalance) (±10%) The relay operates if any of the situations occours The relay releases if any of the circumstances fails There is a Time Delay between the relay motion and the condition occours (except rotational direction of phases error ) to bypass very short interruptions or different non permanent disasters A selector change allows collection of an adjustable time delay from 0 to 10s When the provision returns towards its rated value, the relay is re-energised in step with the hysteresis cost (5%)
