Product / Solution: Active Harmonic Filters

Location:

The Problem: PHA India received a notice from TNEB to control the harmonics being generated within the limits set. Large part of the harmonics was generated by the welding process at its facility.

Fuji Electric Solution: After a full inspection and study the team recommended installation of a 400Amp AHF to control harmonics. In the pre installation phase it was found that the current variation was very high between 30 to 100%. This was due to all machines being connected with 2 phase. Due to the load current variation and the unbalance current the AHF was not able to keep the harmonics within limit. Based on this feedback, the R&D team of Consul Neowatt developed ad new firmware for welding applications.

Result: Installation of the 400Amp AHF with new firmware was able to bring the total harmonics within the limit set by TNEB.
