  1M122 Transformer Parallel Control Scheme

  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

  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

  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

  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

  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…
