Three-phase voltage stabilizers are widely used not only in industrial facilities. They can be used in cottage villages, social infrastructure and small businesses. In some cases, even a three-phase network can be connected to residential buildings, so its use as a voltage stabilizer for the house is not ruled out. An ideal three-phase network should have a voltage level of 380V, but this is not always observed, so three-phase voltage stabilizers are used to normalize the network.

What is a three phase stabilizer? At its core, a three-phase voltage stabilizer is three independent single-phase stabilizers, which are combined by a common control circuit, and in case of phase imbalance or its shutdown, the circuit will completely shut off the entire stabilizer. Single-phase devices are connected in such a way that each phase has its own phase, and zero is common to all blocks. In addition, the housing of the three-phase stabilizer must be grounded.

SUNTEK voltage regulator responds to the following voltage fluctuations in the network:

Phase voltage is below a critical level;

Phase voltage above critical level;

The temperature of the elements of any block exceeded a certain threshold.

Sometimes when connecting consumers, a situation may arise with an uneven load on individual phases, which is called “phase imbalance”. The controller inside the stabilizer carefully monitors the situation and, with a large phase imbalance, immediately disconnects the load on all three phases. Three-phase voltage stabilizers are a vertical floor construction. In addition to the controls, voltage indicators are located on the front panels. The scope of three-phase stabilizers is extremely large. Three-phase voltage stabilizers for the home usually have little power. It can be limited to 30-50 kW. Stabilizers with a power of up to 100 kW are used to power small cottage villages, as well as in small businesses. Three-phase voltage stabilizers with a capacity of up to 1 MW are used in large industrial enterprises.
