Transformer Regulation

Voltage regulation and tap changer control relays.

  • 1M122 Transformer Parallel Control Scheme

    Read more The 1M122 Transformer Parallel Control System is designed to monitor & control the tap changers of up to four (4) transformers connected on a common bus & operating in a MASTER FOLLOWER control configuration. The tap position of each transformer is monitored as well as the raise / lower commands initiated by the selected master voltage regulating relay. Parallel control schemes are available to meet a range of transformer control…
  • 2V164-S Voltage Regulating & Tap Change Control Relay

    Read more The 2V16x Series relays are designed for the control of motor driven on-load power transformer tap changers. The 2V164-S 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-S, considerable emphasis…
  • 2V165-S Transformer Parallel Control Relay

    Read more The 2V16x Series relays are designed for the control of motor driven on-load power transformer tap changers. The 2V165 Series relays are designed to monitor & control the tap changers of up to four (4) transformers connected on a common bus & operating in the master slave control configuration. Master follower parallel control schemes traditionally use auxiliary switches on the tap changers to determine out of step errors. While this…
  • 2V200 Tap Position Indicator (TPI) Voltage to Frequency Sender Unit

    Read more The 2V200 is specifically designed for operation with the RMS type 2V164 Voltage Regulating Relay (VRR) & application on power transformers fitted with on load tap changers. The 2V200 provides a noise immune interface between the tap changer & a remote tap position indicator (TPI), display. The 2V200 is designed to interface with tap changers using either binary / BCD coded signals or a traditional voltage divider circuit. The 2V200…
  • 4D200 Tap Position Indicator (TPI) Display Module

    Read more The 4D200 is specifically designed for operation with the RMS type 2V200 TPI to frequency transducer. The 2V200 provides a noise immune interface between the tap changer & the 4D200 via a 0 to 5KHZ frequency signal. Alternatively the 4D200 may be configured to accept a BCD coded input direct from the tap changer or via a voltage to BCD transducer. Where an RMS 2V164 Voltage Regulating Relay is being…
