Questions & Answers

What is the main function of an APFC Panel manufactured by Aark Electro Tech in Karur, Tamil Nadu?

The main function of our Automatic Power Factor Correction (APFC) Panel is to automatically switch capacitor banks on and off to maintain a power factor close to unity (1.00). This eliminates reactive power losses and avoids expensive penalty surcharges on electricity bills in places like Karur, Coimbatore, Trichy, Salem, Namakkal, and Chennai.

How does a poor power factor impact my factory billing in Tamil Nadu?

Electricity boards (like TNEB/TANGEDCO) charge commercial and industrial customers based on kVAh (Apparent Energy) consumption. A poor power factor draws excess current, causing active energy losses, utility fines, and increased transformer loading. Installing an APFC panel optimizes power usage and reduces kVAh billing immediately.

Why are detuned reactors highly recommended inside APFC panels?

Modern manufacturing plants in Coimbatore or Chennai use non-linear loads (like VFDs, CNC machines, and induction furnaces) that generate severe harmonics. Splicing standard capacitors into a harmonic-rich grid can trigger catastrophic resonant overvoltages. Our detuned reactors block these harmonics, keeping the grid safe.

What types of capacitors do you use in Aark APFC assemblies?

We only install premium quality, self-healing Metallized Polypropylene (MPP) or All-Polypropylene (APP) heavy-duty capacitors. Sourced from globally certified brands, they feature internal overpressure disconnector systems for ultimate safety.

Can you deliver and commission custom-designed APFC panels in Coimbatore, Namakkal, and Salem?

Absolutely! We engineer custom APFC panels matched perfectly to your factory load profiling. We manage direct deliveries, installation guidance, and on-site testing services across Karur, Trichy, Salem, Namakkal, Coimbatore, Chennai, and all neighboring districts.

What safety protections are built into your capacitor correction panels?

Our advanced microprocessor controllers feature dynamic safety trips, including under-voltage/over-voltage protection, over-temperature auto-shutdown, overcurrent protection, and harmonic overload alarm triggers to protect both capacitors and the grid.

How does Aark manage heat accumulation inside heavy-duty APFC panels?

Capacitors and reactors naturally generate thermal heat during continuous switching operations. To maintain safe internal operating temperatures, our enclosures feature dedicated ventilation louvers and heavy-duty, thermostat-controlled cooling fan systems.

Does the panel support manual operation in case of controller maintenance?

Yes, all our panels are equipped with Auto/Manual selector toggles and dedicated manual push buttons for every step. This allows site operators to transition and switch steps manually during inspection cycles, ensuring continuous power factor correction.

Do your APFC panels support remote SCADA and BMS integration?

Yes! Our smart APFC controllers support RS-485 Modbus RTU, allowing factory managers in Chennai or Coimbatore to integrate energy consumption metrics directly into SCADA, BMS, or centralized IoT dashboards.

How does Aark Electro Tech stand out compared to other panel manufacturers in South India?

Aark Electro Tech combines state-of-the-art CNC fiber laser sheet metal fabrication, CPRI type-tested designs, premium low-loss capacitors/reactors, and dedicated round-the-clock technical field service across Karur, Trichy, Coimbatore, Salem, Namakkal, and Chennai.
