Our solutions are designed to optimize electrical systems by improving power factor, reducing harmonics, and enhancing overall system efficiency.


Product-Specific Questions
What are IPFC capacitors?
Intelligent Power Factor Correction (IPFC) capacitors are smart capacitor modules with integrated switching, protection, and control features. They are used in automatic power factor correction panels for dynamic load management.
What are static switches used for?
Static switches enable fast and contactless switching of capacitor banks or filters using thyristors or IGBTs. They are ideal for dynamic or rapidly changing loads like welding machines or elevators.
What is the purpose of HV capacitors?
High-voltage capacitors are used in utility and heavy industrial environments to improve power factor and stabilize voltage at medium- and high-voltage levels (typically 3.3 kV and above).
Why are reactors used in PFC systems?

Detuned reactors are used in PFC systems to:

  • Avoid resonance with harmonics

  • Protect capacitors

  • Reduce harmonic amplification


They are usually tuned to 189 Hz or 134 Hz (depending on the system).


What is an SVG (Static VAR Generator)?
An SVG is an advanced device that dynamically injects or absorbs reactive power in real-time. It provides superior compensation compared to traditional capacitor banks and is highly effective in harmonic-rich environments.
How do active filters work?
Active harmonic filters (AHF) detect and cancel harmonic currents in real time by injecting equal and opposite waveforms. They also improve power factor and reduce THD (Total Harmonic Distortion).
What is a hybrid filter?
A hybrid filter combines passive components (capacitors/reactors) with active filtering to provide cost-effective harmonic compensation and power factor correction in medium to high harmonic environments.
What are power factor improvement panels?

These are integrated systems that automatically switch capacitor banks (with or without reactors) to maintain a target power factor. They are available in:

  • APFC (Automatic Power Factor Correction) Panels

  • RTPFC (Real-Time PFC) Panels

  • Thyristor-Switched Panels

  • Intelligent Hybrid Panels


Installation and Maintenance

Always follow wiring and commissioning guides.


Do surge arresters need maintenance?
While they’re passive, arresters degrade over time. Annual inspections and surge counters help identify performance loss due to repeated surge exposure.
What’s the installation method?


  • Relays: DIN rail or flush-mounted inside panels

  • Arresters: DIN rail (LV), pole-mounted or base-mounted (MV/HV)


Proper grounding is essential for surge protection effectiveness.
