Harmonic is a wave with a frequency that is a positive integer multiple of the fundamental frequency, the frequency of the original periodic signal. The original signal is also called the 1st harmonic. ZDDQ AHF is the expert for harmonic filtering in power system. Main for: Ultra-fast reactive power compensation(Inductive and capacitive); Load balancing between phases and unloaded neutral wir...

As we often say "safety responsibility is as big as the sky" and "safety responsibility is heavier than Mount Tai"! Safe production is everyone's responsibility. Regardless of the nature of the accident, as long as careful analysis, you will find that it is caused by non-implementation of safety regulations and illegal operations. Safety work has only a beginning and no end. The above picture was ...

Static Synchronous compensator (STATCOM) is a fast-acting device capable of providing or absorbing reactive current and thereby regulating the voltage at the point of connection to a power grid. It is categorised under Flexible AC transmission system (FACTS) devices. The technology is based on VSCs with semi-conductor valves in a modular two-level configuration. ZDDQ Statcom have installed in many...

ZDDQ Active Harmonic Filter Active harmonic filter is connected in parallel with non-linear loads, and uses one set of CT to detect the load current. It calculates each order harmonic current by FFT algorithms in its DSP microchips, and then generates a compensating current with the same amplitude but opposite phase angles to the detected harmonic current, which cancels out the original load harmo...
