🔎 Selection Tips

 

  • Distribution network equipment (35kV and below) : Select 60kV series .
  • Mainstream equipment in substations (110kV) : 120kV series is selected.
  • Power transmission and transformation equipment (220kV) : 200kV series selected.
  • Ultra-high voltage equipment (330kV) : 300kV series should be selected.
  • Ultra-high voltage equipment (500kV) : 400kV series should be selected.

For surge arresters, prioritize low current (2/3mA); for cables/transformers, prioritize high current (5/10mA).

 

Core Product Advantages

 

  1. High voltage output, covering all scenarios : The rated voltage can reach up to 400kV, covering the testing needs of power equipment of all levels from 35kV to 500kV. One device can meet the on-site testing requirements from distribution network to UHV, without the need to switch between multiple devices.
  2. High-precision and stable output, reliable data without rework : voltage/current measurement accuracy ≤ ±1%, smooth voltage adjustment across the entire range, ripple coefficient ≤ 0.5%, good repeatability of test results, qualified data can be obtained in one test, without the need for repeated tests and wasting time.
  3. Multiple safety protections ensure safer on-site testing : Built-in overvoltage, overcurrent, zero-position start, grounding, and wire breakage protection, with nanosecond-level rapid shutdown, effectively prevents damage to equipment and samples, reduces on-site operational risks, and makes the testing process safer.
  4. One-click surge arrester testing significantly improves efficiency : Standard configuration includes a one-click switching function from 0.75UDC to 1mA, eliminating the need for manual calculations and repeated adjustments. The surge arrester testing process can be completed with a single click, directly increasing on-site testing efficiency by 80%.
  5. Portable and lightweight, easy for one person to move : It adopts an aluminum alloy chassis + insulated voltage multiplier cylinder structure, which is small in size and light in weight. With the portable case, it can easily handle on-site relocation and high-altitude operations without the need for multiple people to move it, saving labor costs.
  6. Multi-power supply compatibility, suitable for outdoor environments : Supports multiple power sources such as generators, inverters, and mains power, allowing for normal testing even in environments without stable mains power, such as the wild, mountains, and remote substations, without site limitations.
  7. Impact resistant and aging resistant, worry-free long-term use : Moisture-proof, dirt resistant, and high-voltage discharge resistant design, can withstand sudden discharge impact under rated voltage, low equipment failure rate, lower maintenance cost in the long term, and more durable.
