What is a Constant Voltage Transformer - an introduction ... stabilisation can be achieved using a simple magnetic device which has no moving parts. This is a process of producing a constant ac voltage from a varying ac voltage supply and involves the use of saturable reactors. The latter may be incorporated in a special transformer magnetic saturation being produced in a part of the magnetic circuit.[email protected]
Furnace Transformers, Manufacturers, Exporters, Suppliers ... transformers are used to step down from voltages between 11 and 33 kV to levels of several hundred volts only. This results in massive secondary currents. As an example a 30 MVA unit at 150 V would result in a secondary current of 115 kilo Ampere. For these high secondary currents special bushings are required to connect to the bus-bars.Get Price
