F. Description of operation of AC leakage fault detection device (WSD-350): https://youtu.be/1BkGMI20g44
* Purpose: When a circuit breaker trips in case of a cable leakage in a street light, quickly finds it and installs a temporary cable to temporarily supply street light lighting.
Replace the underground cable with a gap.

3. Earth leakage breaker field
A. Active ingredient operation type operation and unnecessary operation prevention type (in case of instantaneous leakage current) operation test of single-phase IGR earth leakage breaker
: https://youtu.be/Dqy8PJy3PNA
- Including a description of the technology roadmap in the field of leakage analysis and interruption.
- The instantaneous leakage current proves that it is a leakage component of the pure capacitance component, and an IGR earth leakage circuit breaker is used.
- Communication company repeater, LED traffic signal controller, and earth leakage breaker for rural village refrigerator tripped due to instantaneous capacitive leakage current generated during lightning strike, but IGR
Solved after using a ground leakage breaker.
B. Operation test of 3-phase IOP earth leakage breaker to prevent unnecessary operation: https://youtu.be/vNROwh8-pac
C. Mutual cooperative operation test between single-phase and three-phase earth leakage breaker : https://youtu.be/Ox9nxZqnfEM
* Conclusion: A single-phase earth leakage breaker must trip earlier than a 3-phase earth leakage breaker for protection coordination
become inappropriate)
* Protection coordination is perfect only when a combination of a single-phase IGR earth leakage breaker and a 3-phase IOP earth leakage breaker is used.
