T/V Series Pressure Relief Valves & Devices

Overview

Pressure rise in liquid-filled transformers is a very important parameter to determine signs of deterioration in performance or upcoming failure.

Pressure Relief Valves and Devices are used to prevent rapid build-up of pressure within the transformer tank.

The Pressure Relief Valve or Device will trigger when accidental, instantaneous, and uncontrolled increases in pressure to avoid an explosion. Certain models allow to direct the oil to reduce the risk to personnel and diminish the environmental impact of an oil spill.

The Pressure Relief Valves (PRV) and Pressure Relief Devices (PRD) are designed to discharge the pressure very quickly and at pre-set thresholds. Our PRV or PRD will discharge rapidly increasing
internal pressures that could be caused by a sudden and violent short circuit inside a transformer. These safety accessories reduce risk of possible injury to nearby personnel, equipment and environmental damages that would be caused by a catastrophic transformer failure.
