RQ B SERIES REACTIVE POWER CONTROL RELAY
RQ B Series reactive power control relays are designed to operate for the reactive power compensation of LV distribution systems .
The logic to operate the steps is completely different from other relays. The logic is designed so that the compensation is achieved
very quickly with most reliable operation.

SETTINGS
Relay should be set properly according to the properties of the systems. In order to achieve best relay operation, all settings should
be done properly and the oeration of all signal leds must be read carefully. The front view of the relay is at Figure 1.
