Typical application scenarios

The case of State Grid Zhejiang Electric Power Research Institute shows that the system equipped with SF6 circuit breaker needs to complete 5 consecutive dual-mode switching tests, and the actual recording shows that the frequency fluctuation is controlled within ±0.15Hz.


Standardized debugging process

  1. Pre-inspection: verification of equipment factory report
  2. Subsystem test: deployment of DSP harmonic monitoring platform
  3. 72h trial operation assessment
