Brief: Discover the ZXJB Single Phase Relay Protection Tester, a cutting-edge device designed for precise relay testing with 0.1ms resolution. Ideal for measuring start values, return values, and action times, this tester ensures accuracy and efficiency in electrical testing applications.
Related Product Features:
  • Measures start value, return value, and their factors of current and voltage type relays.
  • Tests time relays with an error margin of less than 0.2ms for precise action time measurement.
  • Evaluates intermediate relays for start value, return value, holding value, and operation time.
  • Performs reclosing relay tests including capacitance charge, charge time, and reclosing time.
  • Conducts differential relay tests such as DC excitation, braking, and volt-ampere characteristic tests.
  • Features adjustable AC and DC current and voltage outputs with high accuracy (±0.5%).
  • Includes fixed voltage outputs (DC 24V/1A, 48V/1A, 110V/1A, 220V/1A) for versatile testing.
  • Equipped with a digital millisecond meter offering 0.1ms resolution for precise timing.
Faqs:
  • What is the accuracy of the AC current measurement?
