DEVICE FOR TESTING INSULATION heightened tension

摘要

The invention relates to the field of electric power and can be used for testing high DC voltage and the AC power frequency sinusoidal voltage of 50 Hz high voltage electrical insulation. An apparatus for testing the insulation of high voltage, consisting of a circuit breaker autotransformer adjustable throttle on the low voltage test resonant transformer, rectifier, buttons, shunting the rectifier, a current limiting resistor, the test object. A feature of the device is that the primary circuit is additionally introduced capacitor. Moreover, a capacitor may be included either sequentially, or in parallel with the controlled inductor and the primary winding of the resonant transformer. This solution allows the device to operate with electrical insulation which has both large and small capacity. In addition, decreases in response time of the system settings.
