10KVA/400V Induced Withstand Voltage Test Device
Darui Electric recommends:
10KVA/400V Induced Withstand Voltage 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 test voltage higher than the rated voltage is applied across the windings of the transformer under test using a power frequency source, 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 higher than the rated voltage without saturating the iron core, the method of increasing the power supply frequency (f) can be adopted, and a power source with a frequency greater than the power frequency must be used.
Product Overview:
10KVA/400V Induced Withstand Voltage 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 perform induced high voltage tests on the longitudinal insulation of transformers and the main insulation of semi-insulated transformers.
Operating Environment:
1. Power supply conditions: three-phase 380V/50Hz
2. Ambient temperature: -15℃ to 40℃
3. Altitude: not exceeding 1000 meters
