TSP(Momentary Voltage Hunting and Blackout & Solution Concept)

TSP is protect your machine and electrical tool from Sag and moment voltage hunting, blackout, power cut and power failure

1. TSP application (The second power))

1) Nature’s factors : Lightning strikes, mountain fire, snow storms, line faults, overgrown vegetation, flash over, animals,..

2) Artificial factors : Power line system troubles (disorder), utility networks troubles, overload operation,..

3) Normal duration time : within 0.5 sec(80~90%) à 1sec compensation is enough

2. Power trouble influence àtime & cost loss

1) Control system shut down (Unexpected)

2) Data loss

3) System rebooting

4) Abnormal errors increasing on the electronic systems

5) Transformer noise & overheat

6) Motor down & noise,….

3. Sag management in the semiconductor & display lines

1) 0.5~1.0 sec defense system

Procurement suggestions

Momentary voltage blackout and hunting protection devices (e.g., constant voltage transformers or active filters) offer an alternative to UPS for sensitive industrial loads like PLCs or servo drives. These systems correct sags, swells, and harmonics without battery dependency. Ideal for facilities with frequent sub-cycle disturbances but stable long-term power. Choose suppliers providing IEEE 1159-compliant disturbance logs and ride-through validation. Avoid passive solutions that don’t address phase imbalance or frequency drift—verify response time (<2 ms) and efficiency (>95%) under full load. (for reference only)
