Transformer Advantage CTX


Oil, Winding & Ambient Temperature Monitor for Oil-Filled Transformers
Extra channel for ambient.

The Transformer Advantage is a precision ambient temperature monitor for liquid immersed power and distribution transformers. It is rugged, fully electronic and field configurable. With Transformer Advantage, users can extend transformer life, utilize maximum capacity and reduce maintenance costs.

Seven models in the Advantage line offer a range of functions and configurations. All use an accurate and stable platinum temperature sensor (RTD) to precisely measure critical liquid temperatures. Probe options fit most popular thermowells, or magnetically mount on units without wells. Setpoint relays can activate alarms or multiple stages of cooling at different temperatures. A sequencing function equalizes run time between cooling stages. The fan timer can exercise fans at a preset time each day.

Advantage CTX
The Advantage CTX adds an extra temperature channel to the capabilities of the Advantage CT. This channel is typically used to monitor ambient or bottom oil. Many control and alarm schemes are possible with up to 11 setpoint relays.

  • Two RTD inputs.
  • One to three winding current inputs.
  • Winding temperature calculated per IEEE guide.
  • Up to 12 relay outputs for cooling and alarms.
  • Analog retransmits.
  • Cooling fan readback.
  • Auxiliary inputs.
  • Loss of life (insulation aging).
  • DNP-3 & Modbus protocols.

Advantage CTX part numbers begin with G5E or G5L; older models with G5R
