Printing Industries Solution

Typical Challenges

• Recurrent tripping and malfunction of printing machine (city line/high line)
• Low power factor
• Increased losses due to high harmonic distortion and low power factor
• Interruption in operation of continuous printing machines

Root Cause Analysis

• High level of harmonic distortion generated by AC/DC drives at city line machine identified as main reason of tripping related issues
• Low power factor (true) due to high harmonic distortion and use of DC drives

Solution

• P2 Power Active Harmonic Filter at major nonlinear loads especially city line/high line (p2p-415- af3)
• P2 Power Hybrid Filter (p2p-415-hf3) - best suited when power factor is low

Benefits

• Total current harmonic distortion maintained within limits specified as per IEEE standard (iTDD <8%)
• True power factor maintained close to unity
• Significant savings through elimination of failures and power factor improvement
• Optimum capacity utilization of transformer
• Reduced harmonic and reactive losses
• Elimination of interruption in printing process such as paper break, low printing quality etc
