Description
Control transformers cover the range from 50 VA to 7.5 kVA, single- or three-phase, with vacuum varnish impregnation and a screen between the windings. Power transformers start at 7.5 kVA and go up to 500 kVA. They are made with separate windings or as autotransformers, and the class H varnish impregnation is done under vacuum. There are isolating, buck-boost and energy-saving models. Starting autotransformers are designed for motors of 10-350 hp at 380-440 V. The reactors are single- and three-phase, including line input and output reactors, interbridge reactors and smoothing chokes. Such transformers are also used in voltage stabilizers. The version is defined by the technical specification, and if necessary the unit is supplied with an enclosure with instruments and circuit breakers.
How to choose
The division is by power. Up to 7.5 kVA choose the control version, above 7.5 kVA and up to 500 kVA the power version. For matching voltage without galvanic isolation an autotransformer is suitable, and where isolation is needed it is replaced by the version with separate windings. If the voltage must be changed smoothly, see the Regavolt. To reduce consumption with an output of up to 12% and savings typically up to 10%, consider the PowerSave EST. High-voltage needs of 80-150 kV are covered by a separate range.
