It operates with a settled operation time. More Details >>
It is impossible. It is required to combine with MZT type ZCT dedicated for our products. More Details >>
In steady state, it is 5.0 VA, and during operation, it is 6.0 VA. More Details >>
Because this relay derives the control power from input of the CT secondary current, when the input current falls below about 0.5 A for 2-phase input or abou... More Details >>
That is described as below. (1) By laying ZCTs for two feeders having different loads, detected by one earth fault directional relay. In this case, it i... More Details >>
