Three Phase Oil Cooled Servo Voltage Stabilizer Overview

High-Capacity Servo Voltage Regulation Above 1000 KVA

Three Phase Oil Cooled Servo Voltage Stabilizer above 1000 KVA is designed for large electrical installations where variations in incoming three-phase voltage can affect sensitive, high-capacity or continuously operating loads.

The stabilizer continuously monitors incoming voltage and automatically changes the correction level when deviations are detected, maintaining a controlled output according to the selected configuration.

A variable-speed, high-torque DC servo motor proportionally controls the correction mechanism. Motor speed and movement respond to the magnitude and rate of the detected voltage fluctuation.

Proportional correction is designed to reduce overshoot, undershoot, oscillation and repeated hunting while allowing a smooth response to changing electrical conditions.

Oil-cooled construction provides the thermal architecture required for this heavy-duty, high-capacity stabilizer category and supports operation under demanding industrial conditions.

A common electronic PCB coordinates three-phase sensing and correction functions. This helps maintain coordinated regulation across the incoming three-phase electrical supply.

Special control circuitry also supports operation with compatible generator supplies, making the stabilizer suitable for facilities that use both utility and genset power.

Audible alarm indication is provided for applicable abnormal or trip conditions. Exact protection, bypass and alarm functions should be confirmed against the selected above-1000-KVA configuration.
