Induction voltage regulator
The induction regulator is a CONTINUOUS ON-LOAD CONTROLLER of voltage or current. Its design is similar to that of an asynchronous motor with a wound rotor. It operates as a rotating field transformer in a power range of 30 kVA to 3 000 kVA.
Like a wound rotor asynchronous motor, it has a rotor and a stator. The rotor can be rotated by + or - 180° to vary the electrical voltage. There are no moving contacts and the simple design ensures high reliability.
High intensity transformer
The high-current transformer can go up to 80,000 Amperes and can be combined with a VARIVOLT for currents in excess of 10,000 amps.
Each column is made up of several alternating elementary transformers.
The high-current transformer can also be used on a test platform.
Specific studies on request.
Rectifier set
The rectifier unit is a component used to transform AC voltage into DC voltage. It consists of one or more diode bridges, also known as "Graetz bridges".
In our applications, the rectifier unit is generally placed downstream of a Varivolt® (transformer with variable voltage on load), which enables us to obtain a variable DC power supply.
This supply is generally low-voltage but can reach intensities of continuous 30.000 A.
