120kv 5mA hipot test

DC Hipot tester/ XHZG Series DC High Voltage Generator
  Application    XHZG is the special equipment of DC voltage withstand test and leakage current test for the light arrestor, cable and HV equipment for the power department and industry or mine customers. The device is the updated replacement for which is developed based on PRC Energy Department's Standard and complied with the requirement of No-Gap Oxygen-Zn Light Arrestor(GB 11032-89).  The XHZG adopts new technology, new material and new parts with the features like: big power capacity, small volume, light weight and the protection functions like reliable over-voltage, over-current and 0-voltage position switch-off. It has 0.75 times voltage storage and time relay and can set timing sound alarm in the testing. The whole instrument is portable ,easy operation, safe and reliable which is quite suitable for the site test of power department.   Technical data  Power supply:  AC220V(1±10%)   50Hz(1±10%)  Indication accuracy of output voltage:        < 1 class  Indication accuracy of output current:        < 1 class  Wave coefficient:   ≤0.5%  Indication accuracy for 0.75 times output voltage:  < 1 class with lock storage  Comparative humidity:      no more than 85% when 25°c,no dew  Operation method:   interval application 30 minutes  Temperature:  -10°c~40°c  Altitude:  under 1500m  Features  1.Light and portable for site application The instrument is small volume and light weight and portable.   2.Seal-type,good mechanical strength and humidity-proof ,anti-dust.  The high voltage circuit, current-limit resistor and measuring resistor are all sealed in one metal shelter without the influence of environment humidity and dust. It can work in humid, tough wind and 20°c~40°c environment stable function and high mechanical strength.  3.High accuracy With two functions to measure the leakage current (load current) at high voltage end and low voltage end. Measuring leakage current at high voltage end adopts ball-type shielding digital display, no shift change with accuracy 1μA or 0.1μA clear indication, high accuracy and no worry of discharge impulse. The leakage current of instrument is less than 1μA Two levels for high voltage and measurement: with high stability high accuracy resistor the control box has HV output voltage and current plug which can connect with high accuracy meter to measure or calibrate.  4.Auto-protection and safe, convenient operation With adjustable valve value for over-voltage, over-current protection, 0-voltage position and earthing protection. The voltage adjustment button can't start if not at  0-voltage position and if earth -wire not well connected and no misaction. The high voltage generator is seal earthed with no high voltage tap disclosed easy operation and strong anti-interference.  5.High reliability Power frequency 220V is applied to transformer after self-coupling voltage adjustment, then output high voltage when rectified. Seldom malfunction happens due to the simple circuit. The high voltage generator has good sealing and high reliability.  Data sheet
