Description

Dual Independent Breakers
- Simulate two breakers simultaneously with dual-trip/dual-close logic for complex grid scenarios[Primary Keyword: Dual-Trip Dual-Close Simulator].
Phase & Timing Flexibility
- Seven-phase selection (A/B/C/AB/BC/CA/ABC) and adjustable timing (10–90ms trip, 20–180ms close, 10ms/20ms steps)[Long-Tail: 7-Phase Trip Selection].
Robust I/O Configuration
- Isolated DC output (110V/220V, 200W) powers relays, while NO/NC contacts (5A DC/3A AC) mimic real-world auxiliary signals[Secondary: Substation Testing Device].
Versatile Compatibility
- Operates via 100–250V DC input with selectable coil resistances (100Ω/200Ω/400Ω), adapting to diverse relay types[Primary: Relay Protection Testing Equipment].
