Existing problems

- A large number of harmonics are produced during high speed operation of elevator;

- Zero-sequence harmonics are superimposed on the neutral line, leading to the cable overheating, high voltage to ground and other problems, and even causing electrical fire and other accidents.


Solution

ZAPF-130/415-AM active power filtering device of SSE was applied


Control effect

Solved the cable heating, control signal being affected and other problems caused by too large neutral current, harmonics reactive power and so on, ensured the safety and stability of the elevator operation, and reduced the faults caused by the power quality problems.
