Reverse Power Relays

Teknika offers a Reverse Power Relay, TE 800. This is an RYB sensing relay, 6-10 %. This series RPR relay monitors the power flowing in the phases. The direction of the power is checked. The relay monitors current flowing in the B phase. This current is squared with the voltage in RY phase and motoring condition detected. Power sensed is compared to a reference and a timer is triggered above limit. Timer can be set 0-10 sec. Contacts changeover occurs on time out and an LED indication signals closure. The size is 70 x 60 x 110 mm.
