IHF - Industrial Tuned Harmonic Filters

Present industrial processes place high demands on electric power supply quality. The loads on the power system such as rectifiers, variable speed drives, welding machines, converters, and arc furnaces generate harmonic currents. The problems might occur due to extreme harmonic currents.

Voltage fluctuations and interruptions
Overloading and failure of unturned capacitors
Damage or malfunctioning electronic equipment
Overheating of motors, transformers and cables Tuned Harmonic Filters eliminate
these problems by reducing the harmonic content and also by generating reactive power

Power Factor Correction

Voltage improvement
Reduction of system losses
Lower utility bills
Increased system capacity

Harmonic Filtering

Avoidance of harmonic resonance
Reduction of voltage distortion
Lower maintenance
Fewer nuisance tripping of fuses, breakers and relays
Proper functioning of electrical equipment

PQ TECH has over 20 years experience in the domain of harmonic studies, equipment specification and design and manufacture of harmonic filters. PQ TECH has supplied harmonic filters to industry worldwide with installations on all continents. With reliable capacitor technology since 1956, PQ TECH can serve more exact harmonic frequency tuning ranges. This is very important for running of high pulse rectifier drives and both AC and DC arc furnaces.
