L.T. Automatic Voltage Stabilizers hold its potential for units having either L.T. Supply or low capacity H.T. connections. L.T. Servo Stabilizers prevents direct exposure of fluctuating voltage to critical electrical equipment in any establishment. It also prevents frequent tripping of overload and over / under voltage relays to ensure uninterrupted production. These are designed for Balanced Supply and Unbalanced Loads as well as Unbalanced Supply and Unbalanced Loads. The range of input supply for stabilizer depends upon the voltage condition at the supply point. However, some standard ranges for L.T. Automatic Voltage Stabilizers are as under.
