APFC Panel

Shrinath Electric’s Automatic Power Factor Correction System is exclusive with its Custom Based Design, supported by the Load Study Conducted on-site with High-Speed Power Quality Analyzer with recording interval selected as appropriate to the study, counting on the loading pattern.

The system is essentially designed as a series RLC Circuit to suppress the transient inrush current while injecting reactive current. Its Components Selection is critical thanks to the inherent operating parameters of the Capacitors, which pulls high inrush current during switching and while opening out. The Electrical charges remain within the capacitor, thereby build up the Restriking Voltage. These characteristics of the Capacitors need careful study and selection of the right components to make sure an extended life for the entire system.

The choice of capacitor duty contactors with damping resistors protects from inrush current during switching. The coil-wound inductors provide additional protection from short-time high current peaks

The sequential cyclic switching of capaacitors with preset time delay for safe discharge of capacitors increases the lifetime of capacitors. It avoids problems rooting from voltage peaks while energizing the charged capacitors at sinusoidal peak instants of the availability voltage.

The selection of capacitor stages with appropriate stage ratios matching the load profile provides power factor correction with high resolution.

The State Electricity Board commonly utilizes automated Power Factor Control Panels to maintain the Power Factor. It’s essential to know the Power Factor because it’s a ratio of active to perceived power used when calculating electrical consumption. Everyone is aware of the rising cost of electricity. When a result, it becomes critical to cut electrical consumption to save money on utility bills by operating at a targeted power factor to avoid paying an undesired electricity penalty as the power factor drops over time.

When using an APFC Panel with a stage-based pre-programmable micro controller of varying make, the reactive load is detected directly using the VAR (Volt Ampere Reactive) sensing principle, which triggers the capacitor banks of appropriate capacity automatically in multiple stages. This keeps the PF at 0.99 Lag. By State Electricity Board or Corporation or private undertaking protocol, APFC Panels are widely employed to control industrial power consumption by stabilizing Power Factor.
There is a lot to learn about APFC Panels, from the basics like what they are and what they do, to how they perform in delivering electrical utility services. We are the most promising electrical panel manufacturer in Gujarat and APFC distribution panel manufacturer.

For the necessity of APFC Panels, we will investigate the design characteristics and controls used to achieve a balanced power factor.
