In three phase systems, it measures RMS values of AC voltages, currents and system frequency sensitively. Using up direction button (Select) phase-neutral voltages and phase-phase…
In one phase systems, it measures RMS values of AC voltage, current and system frequency sensitively. DP02-72 has many features. Those are; - Over Voltage…
Microprocessor controlled. Three or single phase relay is used in systems exposed to over or under voltage, such as command, control or compensation systems and…
