TWSK-Y Oil-Immersed Transformer Temperature Controller

TWSK-Y Oil-Immersed Transformer Temperature Controller

The TWSK-Y intelligent temperature controller is specially designed for oil-immersed transformers. It continuously monitors transformer oil temperature and provides clear digital display. Based on oil temperature conditions, it automatically controls the cooling fan and activates over-temperature alarm and trip protection to ensure safe and stable transformer operation.

The controller uses a YT Series armored PT100 oil temperature sensor with a three-wire connection and cable length of up to 20 m. It provides accurate temperature measurement without temperature compensation or calibration. With built-in RS485 communication, the controller supports remote monitoring and management of transformer operating data.
