Discover our ranges to ensure voltage correction in an automated way, IPOWER regulators are the guarantee of perfect protection of your electrical equipment against problems such as voltage variations or overloads Electrical.
Available for rated powers from 1200 VA to 600 KVA in single-phase or three-phase, conventional or wall models, our products are also effective in the event of a voltage drop as they maintain output tension in a consistent manner. regardless of the load or voltage of entry.
The automatic voltage regulator is used to
Working Principle of Voltage Regulator
It works on the principle of detection of errors. The output voltage of an AC generator obtained through a potential transformer and then it is rectified, filtered and compared with a reference. The difference between the actual voltage and the reference voltage is known as the error voltage. This error voltage is amplified by an amplifier and then supplied to the main exciter or pilot exciter.
Application of the Automatic Voltage Regulator
The main functions of an AVR are as follows:
It controls the voltage of the system and has the operation of the machine nearer to the steady state stability.
It divides the reactive load between the alternators operating in parallel.
The automatic voltage regulators reduce the overvoltages which occur because of the sudden loss of load on the system.
It increases the excitation of the system under fault conditions so that the maximum synchronising power exists at the time of clearance of the fault.
