AC VOLTAGE STABILISERS & REGULATORS
1.0General
This specification covers the electrical aspects for a Magnetic InductionOil Immersed Three Phase AC Voltage Stabiliser that shall provide automatically stabilized and regulated power to sensitive electrical and electronic equipment.
As a Magnetic Induction based solution, theStabiliser shouldbe based around a rotor and stator design principle to increase or reduce the magnitude of the voltage in a series transformer winding, thereby delivering and maintaining a constant output voltage. The arrangement should be similar to a motor, except that the rotor does not rotate continuously. Its maximum rotation should be only 130 degrees. The magnetic coupling between the rotor (the shunt winding) and stator (series winding) should cause the magnitude of the voltage in the series winding to increase or decrease, depending on the angle or position of the rotor to the stator. For example, when the input voltage drops, the rotor will rotate clockwise to such an angle to make up for the drop in voltage, rotating anti-clockwise to correct for a high voltage.
The AC Voltage Stabiliser is to be an Ashley-Edison (UK) IVSI-H-3P-X468Seriesmodel, or approved equalof similar high quality and offering similar comprehensive features and warranty options.
