Harmonics are unwanted currents that overload wiring and transformers, creating heat (or Fire) and interefear with utility Load. It can also hamper operations and cause equipment failure.The increased use of nonlinear devices/eqipments has become a concern in most utility power system. Non linear Loads draw a current but unable to measure by normal electrical instruments.

Modern Computers, Chargers, UPS, Inverter and other IoT based devices convert utility AC power supply into Regulated DC power supply through IGBT,MosFET,Diode etc. Moreover Neutral carries Zero sequence current which is very harmful in Normal and earth fault conditions. Our Zero Sequence harmonics Filter (ZHF) is very useful for three phase circuit. We use protections in Phase & earth circuit. We neglect Neutral which has no protection. We cover up this gray area by our ZHF.

It is useful to filter Harmonics 3rd predominantly and also 5th,7th and % Total Harmonics distortion under certian conditions. It also protect the devices during fault conditions. It also minimises voltage & current unbalance. The unbalance current under normal conditions do not affect Zero sequence current, but under Fault conditions this current increases abruptly. It can damage DC components in the circuit, thus can also catch fire. We manufacture ZHF filter from 30 KVA to 300 KVA, 3 phase. It is a static device, hence no maintenance required. Also in comparison with other Harmonics suppression Filters, this is most economical concept. Causes of fire - All electrical equipments are protected for Phase current and Earth fault. Neutral current/fault not considered at the time of system design. In case of earth fault condition neutral either draw a heavy current or if  neutral is open phase shifted to Neutral catchs the fire. It is better to protect neutral by ZHF Filter to avoid fire.
