Voltage stabilizer Volter-200 pt

The Volter three-phase voltage stabilizer (SNPTT) 200 kW consists of four units – three phase stabilization units and one switching unit.

The stabilizer is connected to the three-phase network via the switching unit. The connection is made according to the "star" scheme with a mandatory neutral wire.

On the front panel of the switching unit there are:
– automatic switch;
– LED indicators of the presence of input voltage and output voltage;
– voltmeters of input and output voltage;
– two voltmeter switches that allow you to alternately measure the phase and line voltage both at the input and at the output of the stabilizer;
– input current ammeter;
– ammeter switch by phases.

On the top panel of the phase unit there is an operating mode switch, on the front panel there is a liquid crystal indicator and control buttons.

Each step-up phase voltage stabilization unit consists of an autotransformer with terminals, power keys and a voltage controller. During operation, the controller monitors changes in the input phase voltage and, in accordance with the measurement results, switches the power keys, maintaining a stable magnetic flux of the autotransformer and a stable output voltage of the stabilizer.
