Dry Type Transformer Monitor

Monitor temperature in up to three (3) Dry-Type transformer windings with the Qualitrol 118 Transformer Monitor. Accurate transformer temperature measurement with cooling system fan control, alarm, trip capability, and two (2) additional relays.

Operators can easily compare the winding with the highest temperature to pre-selected relay temperatures.

Front panel LED indication available for easy viewing.

Features

Real-Time Temperature Monitoring: Continuously monitor three winding temperatures using thermocouples
User Friendly: Front panel includes display, controls, and LEDs for easy status indication
Fan Control Logic: Automatically activates cooling fans based on temperature thresholds, reducing manual intervention and energy waste
Alarm & Trip Outputs: Protects assets by triggering alarms or shutdowns when critical limits are exceeded
SCADA Integration: Easily integrate into SCADA systems using 0-1 or 4-20mA output
Compact, Rugged Design: Built to withstand harsh environments typical of industrial applications.
CE, UL, and CSA Certified

Options

Modbus Communication: Seamlessly integrates with SCADA and building management systems for centralized visibility.
