The Transformer Advantage is a precision Single Channel Monitor 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 measure critical liquid temperatures precisely. 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.
The single-channel Advantage SC directly measures one liquid temperature using either an RTD probe installed in a thermowell or a magnetic probe mounted on the side of the tank. The display prompt can be set to Top Oil, Fluid, Winding, HWinding, YWinding, XWinding, Ambient, or Bottom Oil. Winding temperature is simulated by using the RTD probe in a heated thermowell. Full-scale temperature can be set to either 200°C or 250°C. During setup, each form C setpoint relay is individually configured to activate at different values of the measured temperature, time of day, or remote command. Hysteresis, non-alarm state and sensor fail response are also individually programmable. Analog output and up to eleven setpoint relays are available in the SC model.
- One RTD input.
- Use with heated thermowell for winding temperature.
- Up to 12 relay outputs.
- Analog retransmit.
- Auxiliary inputs.
- DNP-3 & Modbus protocols.
Advantage SC part numbers begin with G3E; older models with G3R
