Hospitality Industries Solution

Typical Challenges

• Flickering and failure of lighting fixtures
• Interrupted operation of lifts/elevators
• Overloading and burning of neutral conductor

Root Cause Analysis

• High harmonic distortion generated by large chiller units, lifts/elevators and lighting loads
• Fluctuating load profile and sudden reactive jerks of lifts/elevators
• Summation of triple-N harmonics in neutral conductor leading to high neutral current

Solution

• P2 Power Active Harmonic Filter at major non-linear loads (p2p-415-af3)
• P2 Power Active Harmonic Filter with Neutral Compensator (p2p-415-af4) - when neutral current is high
• P2 Power Hybrid Filter (p2p-415-hf3) - suitable when power factor is low

Benefits

• Total harmonic distortion maintained within limits specified as per IEEE standard (iTDD <8%, vTHD <5%) - free from any risk of harmonic penalty (if applicable)
• High true power factor; free from any risk of low pf penalty (if applicable)
• Significant savings through elimination of lighting failures and reduced losses
• Uninterrupted operation of lifts/elevators
• Reduced neutral current and overloading of neutral conductor
