What is a Servo Controlled Voltage Stabilizer

What is a Servo Controlled Voltage Stabilizer? Why should I install one?

A Three phase servo voltage stabilizer is a Servo-motor controlled stabilization structure that performs best voltage supply by a Buck transformer booster that captures voltage fluctuations from input and controls current to the right output. An AC synchronous motor adjusts voltage in a clockwise or anticlockwise direction and manages the output voltage with components like a control card, dimmer, comparator, transistors, etc. 

Main Components & their Functioning

Dimmer (Variable Transformer) – It is usually encircling in the shape. Silicon CRGO toroidal core is utilized for the base & copper wire with the explicit turn ratio according to the capacity. The basic principle of a dimmer is to augment or reduce the voltage which is fed to the buck-boost transformer. 50% of the production voltage is amplified or reduced by a dimmer only.

Let us take an instance: If the input voltage is 160V, the dimmer will augment it to 190V & rest of the 30V (since 220V is necessary to run any single-phase load) will be completed by Buck Boost Transformer.

Carbon Brush – This is a stirring part in a Three phase servo voltage stabilizer, it is fixed in the beam to make the contact with dimmer. If the input voltage difference is very recurrent, this carbon brush will remove early and the customer has to reinstate it very often. That is why servo stabilizer manufacturers should make use of the best quality carbon brush.

Servomotor (Synchronizing Motors) – Servomotor as the name suggests is the most important part of a servo stabilizer. The motor rotates the support linked to the dimmer in the clockwise or anti-clockwise direction according to the input voltage.

Buck Boost Transformer – In contrast to the dimmer it is in a rectangular shape. Bobin is fixed with EI CRGO core. When the transformer configuration is built, it is dipped in a varnish tank for an extra shield. This type of Insulating varnish also called transformer varnish is put on all the windings applied in buck-boost transformers to encapsulate them before the servo stabilizer is equipped for regress testing. Transformer varnish improves coil life and guards windings in the transformer from environmental experience that would otherwise get spoiled due to vibrations. This varnish can be applied as a great insulator for any coil of wire.

Contactor – The purpose of the contactor is to cut the productivity of any servo stabilizer if it exceeds a prearranged limit.

MCB, MCCB – The MCB is used to toggle on /off the servo stabilizer and provides short circuit fortification whereas MCCB is usually for overload shield.

Electronic Circuit – As the name suggests, it propels the signal to different parts of a servo stabilizer like motor, dimmer, etc., so it works according to that sign & does its part to correct the voltage.

These are the main components used in servo stabilizers though there are lots of other parts also like voltmeter, ampere meter, connectors, etc. Give us your email address to recognize the functioning of each part. Call our expert to know more.
