2V164 Voltage Regulating Relay for OLTC Control

The 2V16x Series relays are designed for the control of motor driven on-load power transformer tap changers. The 2V164 Voltage Regulator Relay continuously monitors the transformer output voltage & current & provides "RAISE" & "LOWER" control commands to the on-load tap changer such that the load centre is automatically maintained within acceptable limits. Small variations in supply frequency will not affect the system performance. When designing the 2V164, considerable emphasis was placed on producing a relay which would be very simple to install, set up & operate in the field. The result is a simple yet effective & very dependable voltage regulator relay available at a competitive price. The relay is very easy to set up due to the large screen LCD HMI & PC programming port. RMS 2V164 Relays have many in built features to simplify the interface with OLTC's to provide a reliable, effective & simple to operate voltage control system.
