High Voltage AC Test Sets

High Voltage AC Test Sets

High Voltage AC Tests Sets is designed to provide a short-time or continuous high ac Voltage. The frequency is normally 50 or 60Hz, but can be higher in special cases. A typical feature is that the excitation of the low voltage winding (excitation winding) is continuously variable up to the required value and right up to the rated voltage of the Test transformer. A further feature of a Test transformer is that it is able to withstand short-circuit conditions over an arc on a great number of occasions. The time period in which a Test transformer is excited is normally short. It often amounts to one minute, sometimes up to 15 minutes. .
