Low Power Factor
Low power factor is primarily caused by inductive loads such as motors and transformers, resulting in higher demand charges and power factor penalties. Static VAR Generators provide fast and continuous power factor correction, eliminating penalties and improving system efficiency.
Capacitor bank failures
Capacitor bank failures commonly occur due to harmonic distortion and over-voltage conditions, leading to frequent fuse blowing and downtime. Active Harmonic Filters eliminate harmonics, protecting capacitor banks and increasing their service life.
HIGH THD (%) – Current & Voltage Distortion
High total harmonic distortion (THD) is caused by non-linear loads such as VFDs, UPS systems, and SMPS-based equipment. High THD results in equipment overheating, losses, and malfunction. Active Harmonic Filters reduce THD to acceptable limits and ensure a clean power supply.
Harmonics from vfds
Data centres operate with a large number of servers, UPS systems, and SMPS-based loads that generate very high current harmonics and total harmonic distortion (THD). These harmonics cause overheating of transformers, cables, and panels, leading to energy losses and reduced system reliability. Active Harmonic Filters control harmonic distortion, improve power quality, and ensure high efficiency and maximum uptime for data centre operations.
High Neutral Current
Shopping malls use HVAC systems, escalators, elevators, lighting, and IT loads, many of which are driven by VFDs. These systems result in low power factor, harmonic distortion, and power factor penalties imposed by utilities. Static VAR Generators dynamically improve power factor, while Active Harmonic Filters reduce harmonics, helping malls lower electricity bills and maintain a reliable electrical system.
Transformer Overheating
Transformer overheating occurs due to harmonics, unbalanced loads, and excessive losses, reducing transformer life and reliability. A combination of Active Harmonic Filters and SVGs protects transformers by reducing thermal stress and improving load balance.
Power Factor Penalty
Power factor penalties are imposed by utilities when power factor falls below specified limits, increasing electricity costs. SVGs maintain power factor within required limits at all times, eliminating penalties and reducing energy bills.
