PMC 2241-B TRANSFORMER PROTECTION RELAY

Designed for monitoring the temperatures of L.V. windings of the Dry-Type Transformer/Cast Resin Transformers, these instruments display the winding temperatures and take necessary control action as per set and differential values programmed by the user. The protection system also records maximum temperatures attained and will display the same along with corresponding channel number.
This Instrument can be connected to a maximum of 12 sensors and has 4 relays.
