A Temperature Controller for Dry Type Transformer is a critical electronic device designed to monitor and regulate the core and winding temperatures of dry-type transformers. It ensures safe operation by preventing overheating, extending equipment lifespan, and enhancing transformer efficiency in power distribution systems.

This controller operates by receiving temperature signals from built-in RTD (Resistance Temperature Detector) sensors, typically PT100, installed within the transformer windings. When temperatures exceed predefined thresholds, the unit activates alarms, fan cooling systems, or circuit breakers to mitigate thermal risks.

Designed for high reliability, the controller features multiple sensor inputs, user-configurable alarm settings, digital displays, and relay outputs. It is essential for indoor or enclosed transformer installations where precise temperature monitoring is necessary to maintain uninterrupted power performance and meet safety regulations.
