Precimeasure 1007H OTI/WTI is a reliable hybrid Oil Temperature Indicator (OTI) and Winding Temperature Indicator (WTI) designed for accurate temperature monitoring and protection of power and distribution transformers. It provides clear local temperature indication along with electrical signal output for remote monitoring.
The 1007H features a built-in PT-100 sensor and CCU (Current Converter Unit), enabling integration with remote temperature indicators, control panels and SCADA systems. The WTI version uses transformer CT input for winding temperature simulation and hot-spot monitoring.
It is suitable for transformer alarm, trip and temperature protection applications, offering reliable performance for continuous monitoring in substations and transformer installations.
