10KVA/400V Induced Overvoltage Withstand Test Device
Dare Electric recommends for you:
Product Overview:
10KVA/400V Induced Overvoltage Withstand Test Device manufacturer price, for power transformers, voltage transformers and other test objects, in addition to performing external power frequency high voltage tests on the main insulation of fully insulated transformers, it is also necessary to conduct induced high voltage tests on the longitudinal insulation of transformers and the main insulation of semi-insulated transformers.
10KVA/400V Induced Overvoltage Withstand Test Device manufacturer price, according to national test standards, the induced test voltage for power transformers and voltage transformers is approximately 2 to 3 times the maximum working phase voltage. As is well known, when a transformer operates at rated frequency and rated voltage, the iron core is close to saturation. If a power frequency power source is used to apply a test voltage greater than the rated voltage across the windings of the transformer under test, the no-load excitation current will increase sharply to an unacceptable level. From the relationship of induced electromotive force, it can be seen that in order to apply a test voltage greater than the rated voltage without saturating the iron core, the method of increasing the power frequency (f) can be adopted, and a power source with a frequency greater than the multiple of the power frequency must be used.
Operating Environment:
1. Power supply conditions: Three-phase 380V/50Hz
2. Ambient temperature: -15℃ to 40℃
