Current harmonics mitigation in a packing house with numerous Variable Frequency Drives

Challenges in the customer’s packing house

A large automatic packing house was suffering from overheating of the electric boards, failures of electronic devices, PFC systems, and unnecessary downtime of production. Power Quality measurements were conducted by Merus Power’s local partner, POS’s service team. A two-week measurement was performed in two locations simultaneously, at the main packing house and the stacker machine room.

Several problems were detected by the analyzer: High harmonic current distortion and a low power factor at the main board and in the stacker machine room.

Our Merus® Solution

The chosen solution was a 100A Merus® A2 – Active Harmonic Filter that was integrated into the electrical system. In the pictures below, the measured harmonic currents are presented with and without the Merus® A2. As can be seen, the harmonic currents are minimized effectively. The distortion of currents is also minimized and can be seen in the lower pictures.
