HTJS-V Automatic Anti-interference Variable Frequency Dielectric Loss Tester 

Product Characteristics

• 
  

  1. Self-excitation method test for CVT, with one-time wiring, simultaneously measuring the capacitance and tgδ of C1 and C2.

  
  


• 
  

  2. Has the measurement function of external applied voltage and external CN.

  
  


• 
  

  3. The instrument has high measurement accuracy and can meet the requirements of oil dielectric loss measurement. Therefore, only a standard oil cup and special test leads are needed to achieve oil dielectric loss measurement.

  
  


• 
  

  4. Uses frequency conversion technology to eliminate the 50Hz power frequency interference on site, and can obtain reliable data even in strong electromagnetic interference environments.

  
  


• 
  

  5. Grounding protection function: when the instrument is not grounded or poorly grounded, it will not enter the normal program and will not output high voltage.

  
  


• 
  

  6. Overcurrent protection function: the instrument will not be damaged when the test object is short-circuited or broken down.

  
  


• 
  

  7. Built-in standard capacitor and high-voltage power supply, convenient for on-site testing and reducing on-site wiring.

  
  


• 
  

  8. The instrument adopts a large-screen LCD display, and the test process is intuitive and easy to operate through Chinese menu prompts.
  
   

  
  
  

  Product Introduction

  
  
  

  Dielectric loss insulation test can effectively detect overall moisture, deterioration, and local defects in the insulation of electrical equipment. It is widely used in electrical manufacturing, installation of electrical equipment, handover, and preventive tests.

  
  
  

  The anti-interference dielectric loss automatic tester adopts frequency conversion power supply technology, using single-chip microcomputer and electronic technology for automatic frequency conversion, analog/digital conversion, and data calculation, achieving strong anti-interference ability, fast test speed, high accuracy, and simple operation.

  
  
  

  The frequency conversion power supply uses a high-power switching power supply, outputs 45Hz and 55Hz pure sine waves, automatically boosts voltage, and can provide up to 10kV voltage; it automatically filters out 50Hz interference, suitable for on-site testing in substations and other environments with large electromagnetic interference.
