About Us
hello and welcome
Subodhan Engineers (Pune) Pvt. Ltd. has been engineering power quality solutions since 1993. Founded by technocrats with decades of experience in power factor correction, we design, manufacture and supply Capacitors, APFC/RTPFC Panels, Detuned Reactors, Active Harmonic Filters (AHF) and Static Var Generators (SVG) for industries across India.
We are an ISO 9001:2015 certified company, with our manufacturing facility equipped with modern production machinery and in-house testing infrastructure to ensure every product meets the highest standards of quality and reliability.
Built on a strong sense of self-respect and commitment to innovation, Subodhan continues to invest in R&D to deliver customised, dependable power quality solutions for greenfield and brownfield projects alike.
Quality Solutions
Power Quality Solutions
Subodhan offers complete power quality solutions under one roof — from site load studies and harmonic analysis to the supply of APFC panels, Hybrid AHF/SVG panels, and full turnkey power factor correction systems.
Our APFC panels are type-tested for IEC 61921 at CPRI, Bengaluru, and comply with IS/IEC 61439-1 & 2 (Low-voltage switchgear and controlgear assemblies). Our APP (All Polypropylene) capacitors are type-tested and conform to IS 13585 (Part 1):2012 / IEC 60931-1:1996, carrying the ISI mark. Our MPP (Metallized Polypropylene) capacitors are type-tested and conform to IS 13340 (Part 1 & 2):1993 / IEC 60831-1 & 2:1995, also carrying the ISI mark. Ourdetuned reactors , used in our APFC and RTPFC panel series to prevent capacitor–harmonic resonance, are type-tested and conform to IS 5553 / IEC 61558-2-20.
Our Products
Smart Power Solutions for Modern Industries
LV & MV Power Capacitors
- High-quality PP film with pure aluminium foil construction for superior thermal stability
- Engineered to withstand high voltage stress with minimal dielectric losses
- Conforms to IS 13585 / IEC 60931-1 , IS 13340 (Part 1 & 2):1993 / IEC 60831-1 & 2:1995 & IS 13925/ IEC 60871 carries ISI mark
- Extended service life with reduced reactive power losses under continuous duty
APFC / RTPFC Panels
- Automatic power factor correction — contactor-switched or Thyristor Switched Module (TSM)-based
- Type-tested as per IEC 61921 at CPRI, Bengaluru
- Optimised heat-dissipation design for reliable 24×7 operation
- Real-time PF correction that responds instantly to dynamic and fluctuating loads
Detuned Reactors
- Series-connected reactor limits current harmonics and prevents capacitor–harmonic resonance
- Protects capacitors from premature failure, extending operational life
- Purpose-built for industrial environments with harmonic-rich loads (VFDs, welding sets, rectifiers)
- Low-loss, robust construction for continuous industrial duty
TSM
- Provides rapid switching of capacitor banks for dynamic reactive power compensation and power factor correction.
- Uses power semiconductor thyristors (SCRs) for contactless switching, synchronized with the AC supply waveform.
- Consists of inverse-parallel connected thyristors, gate triggering and control circuits, heat sinks, and necessary protection components.
Active Harmonic Filters (AHF)
- Real-time, dynamic reduction of Total Harmonic Distortion (THD)
- Helps facilities meet IEEE-519 harmonic compliance guidelines
- Ideal for critical and rapidly varying loads — data centres, hospitals, process industries
- Extends equipment life and improves overall power quality at the source
Static Var Generators (SVG)
- Instantaneous compensation of rapid reactive power fluctuations
- Maintains power factor in real time, even under sudden load swings
- Fast response time suited to dynamic industrial applications (cranes, presses, arc furnaces)
- Available in compact wall-mount and rack-mounted configurations for flexible installation
Hybrid APFC / RTPFC Panels
- Combines passive capacitor banks with AHF/SVG technology in a single integrated solution
- Thyristor-switched for real-time, seamless power factor correction
- Simultaneously addresses both power factor and harmonic distortion — one panel, two problems solved
- Custom-engineered to match each site's specific load profile and harmonic signature
