Capacitive voltage transformer (CVT) in calibration the test must be conducted under the condition of 50Hz frequency complex geographical condition on site at the same time the traditional experiment device is difficult to meet the requirements of on-site handling testing series resonance booster device is first used in domestic field tunable resonance device has been widely used in domestic 500 kv and below the field calibration of capacitor voltage transformer. Product Characteristics 1 Due to full compensation of resonant reactive power the power of power supply and equipment is less than 1/10 of the required capacity of the subject (1/Q>10). Small size and light weight with the same capacity large output capacity of the device and small power capacity required cheap convenient and safe to use; 2 Series resonance is actually a current filtering circuit so that the current passing through the subject is basically the fundamental current and the waveform distortion rate (THD) of the output voltage is very small which is superior to all existing ac voltage withstand equipment. 3 The short circuit current of the sample after flashover or breakdown is only less than 1/10 (1/Q) of the test current before short circuit which can effectively prevent the expansion of damage to the fault point after breakdown; 4 After flashover the arc will be automatically extinguished immediately. The long (number of seconds) process of restoring resonant state voltage after arc quenching is a steady-state establishment process and there is no danger of voltage overshoot and no danger of restoring overvoltage in microsecond millisecond transient process.

Product Introduction With the continuous update and expansion of modern technology higher requirements are put forward for the reliability of power system and high-voltage equipment. Accidents or damage of electrical equipment are usually closely related to insulation defects. Large capacity of electrical equipment high voltage structure diversification and sealing electrical equipment should be put forward a new higher requirements. With the increasing use of large-capacity equipment the insulation performance cannot be detected by ordinary megohm meter. Power test procedures for a number of power equipment such as: cable motor generator transformer transformer high voltage switch lightning arrester and other requirements to do a series of insulation performance tests the first is to do insulation resistance test. When testing the insulation resistance of large-capacity power equipment the insulation resistance value is related to the pressurizing time. The longer the pressurizing time is the higher the insulation resistance value is. This phenomenon is called insulation absorption phenomenon. In order to understand the insulation performance of the subject it is necessary to conduct the absorption ratio and polarization index test first so as to provide safety guarantee for the next leakage dielectric loss partial discharge and insulation performance test. According to the electric power standardization regulations our company specially introduces BC2010 Insulation Resistance Tester with large capacity high anti-interference and stable performance which can conduct Insulation absorption ratio and polarization index tests on electric power equipment providing accurate judgment in the early stage for series Insulation tests.
