VOLTAGE COMPENSATOR

 

The voltage compensator is designed to compensate voltage dips in an ac electric power system. The compensator contains a controller attached to manage a relevant sequence injection inverter. The supply voltage with/on a respective phase is managed by the controller to generate control signals. The voltage compensator is equipped with a series injection inverter, current sharing static switch, an energy storage division and a system controller.
There are kinds of voltage compensators available with different characteristics and uses for various industrial applications. Automatic voltage compensator includes a digital voltmeter to assess the line voltage in sequence and related circuitry to recompense the welding current in response to the measured line voltage to hold the welding current continuous and independent of line voltage variations.
A UPFC based voltage compensator (Unified Power Flow Controller) is devised to provide and control fast-acting active and reactive power compensation simultaneously on high-voltage electricity transmission networks.
Line voltage compensator is used for resistance spot welding machines of diverse configurations and provides maximum time for triggering times and compensates the fluctuations that affect the welding process.
Voltage dip compensator compensates the voltage during voltage dip to apprehend the power load interruptions. The 'mystery tripping' is prevented by using tap changer high competence transformer with commendable switch processor for 3 seconds time support.
Low voltage compensator is a device which assists to defeat the problem of low input voltages to electronic equipments when being operated from badly regulated supplies by taking the input energy and converting it as ultrasonic frequencies to a direct current voltage which is subsequently added in series with the input in order to obtain a constant output voltage.
