Overview zinc oxide arrester tester is a special instrument used to test the electrical performance of zinc oxide arrester. The instrument is suitable for live or power failure detection of zinc oxide arrester of various voltage levels so as to timely detect the internal insulation damp and valve aging and other dangerous defects. zinc oxide arrester tester is easy to operate and easy to use. The whole measuring process is controlled by single chip microcomputer. It can measure the total current resistive current and its harmonics power frequency reference voltage and its harmonics active power and phase difference. The instrument uses digital waveform analysis technology harmonic analysis and digital filtering software anti-interference methods to make the measurement results accurate and stable. Parameter: 1. Full current measurement range: 0-10mA effective value 50Hz/60Hz accuracy: (reading 5% + 5a) 2. Measurement accuracy of resistive current fundamental wave (secondary method without Interphase Interference): (reading 5% + 5a) 3. Current harmonic accuracy: (reading 10% + 10a) 4.

Product description Transformer Standard current transformer are also called precision current transformers, current transformer standards, standard CT and current transformer standards. Transformer standards are divided into current transformer standards and voltage transformer standards. Standard current transformers are used in the error test of transformers. Used as a current transformer calibration standard technical parameter 1. Temperature: 2. Relative humidity 3. Rated Primary Current:5-5000A 5A,1A 4.Rated secondary current:5 1A 5 Accuracy Class 0.05S 6. Allow long-term work under the rated current; More than120A across the core. Precautions: 1. The current of standard CT and tested CT must be the same in CT calibration. 2. Follow the given wiring diagram strictly. 3. Test whether the load box is accurate or not before calibrating the transformer. 4. Forbid secondary winding opening during the calibration. 5. Select demagnetization before calibration.The wiring diagram is shown in figure 5. Short out the secondary winding before cutting off the power when the demagnetization is finished. 6.Principle wiring diagram of CT with large current generator is similar to above diagram. They are the same except the output winding of large current generator and primary winding of transformer are the same one.
Product Introduction 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 Parameters Technical parameters Rated Capacity 80kVA rated voltage 160kV Adjustable inductance range 65~130H Rated frequency 50Hz Rated current 0.5A Adjustable gap range 0~300mm
