Induction voltage regulator
The induction regulator is a CONTINUOUS ON-LOAD CONTROLLER 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 an asynchronous motor with a wound rotor, it has a rotor and a stator. The rotation of + or - 180 ° of the rotor allows the variation of electric voltage. There is no moving contact 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 set is an element allowing to transform an alternative tension into continuous tension. This one is constituted by one or several bridges of diodes which we also call " bridge of Graetz ".
In our applications, the rectifier set is generally placed in the downstream of a Varivolt ® (transformer with variable voltage in load), which allows us to obtain a variable continuous supply.
This supply is generally low-voltage but can reach intensities of continuous 30.000 A.
