Harmonics are current and voltage waveform distortions in power supply that generate heat in the power delivery equipment and can cause severe damage.
Harmonics can cause excessive tripping of circuit breakers, transformer failures and also impact the Power Factor.
Harmonic Filters are LCR combination circuits that are capable of removing unwanted harmonic currents.Passive Harmonic Filters are designed to provide an alternate path for the harmonic currents and thus keep the main supply lines close to the fundamental frequency. Harmonic Current will pass through the filter which can be grounded.
What EMIS Offers
EMIS Passive harmonic filters are designed and manufactured to provide an economical solution in harmonic mitigation in Power Systems by maintaining THID 5% in compliance with current and voltage requirements of IEEE 519.
They are effective in suppressing harmonic currents and decreasing voltage distortion occurring in the sensitive parts of the Power system.
