The Enhanced PT Cabinet is an integrated solution that builds on the LOPS core technology and adds full PT cabinet functionality. It delivers nanosecond-level overvoltage monitoring, megajoule-level energy absorption, and peak-clipping suppression, while also providing voltage conversion, power distribution, and resonance suppression — all in a single, space-saving cabinet
Main Functions:
Electrical Isolation:Provides electrical isolation between primary and secondary systems, ensuring the safety of secondary equipment and personnel.
Voltage Conversion & Measurement:
Supplies voltage signals for relay protection and metering cabinets.
Power Distribution:
Provides operating power for secondary systems and auxiliary equipment.
Resonance Suppression:
Equipped with both primary-side and secondary-side resonance suppression devices.
Overvoltage Suppression:
Utilizes overvoltage peak-clipping technology to clamp busbar residual voltage to below 1.8 × rated voltage, eliminating system overvoltage protection blind spots.
Energy Absorption & Discharge:
Megajoule-level energy absorption capacity, flexible energy discharge technology, and grounding overvoltage suppression technology ensure strong energy handling capability, preventing the explosion issues of conventional arresters caused by ground counterattack overvoltages.
Overvoltage Monitoring:
Nanosecond-level system status monitoring with 10 MHz ultra-high sampling frequency, capable of recording waveforms of all overvoltage events, including lightning overvoltages.
