South Africa has Africa's most developed manufacturing, mining and automotive industries. Years of load-shedding have made backup power, solar and inverter systems mainstream, so demand for UPS and inverter transformers, chokes and harmonic reactors is strong.
VA Electricals designs and manufactures three-phase harmonic filter reactors at its works in Bhosari, Pune. Every unit is built to your voltages and rating and tested in-house, then packed for export to buyers in Johannesburg, Ekurhuleni, Pretoria and across South Africa.
Rated for 230 V single-phase / 400 V three-phase, 50 Hz systems, with reactor tuning and current rating matched to your capacitor bank and system.
A harmonic filter reactor reduces harmonic distortion caused by non-linear loads such as VFDs, UPS systems and rectifiers. Connected in series with capacitor banks, it detunes the circuit so capacitors are protected from harmonic resonance while power factor is corrected.
For facilities in South Africa with many VFDs, UPS systems or capacitor banks, harmonic filter reactors keep distortion under control and protect equipment from overheating.
Mitigate harmonics from VFDs and non-linear loads to improve power quality.

Tuning, current rating and dimensions to your panel design.
Platinum, gold and coal mines in Gauteng, North West and Mpumalanga run pumps, hoists and conveyors.
Typical use: Harmonic filter reactors for power quality and APFC panels.
Load-shedding has driven rapid growth in rooftop solar, battery and inverter systems.
Typical use: Harmonic control where inverters feed site distribution.
Vehicle plants in Gqeberha, Durban and Pretoria and their suppliers run large production lines.
Typical use: Harmonic filter reactors for power quality and APFC panels.
Panel builders in Johannesburg and Ekurhuleni supply mining, industrial and commercial projects.
Typical use: Detuned filter reactors in APFC and harmonic filter panels.
Johannesburg and Cape Town are Africa's largest data-centre markets.
Typical use: Harmonic filtering where UPS and IT loads distort the supply.
Municipal water utilities and mines run large pumping and dewatering systems.
Typical use: Filtering harmonics from large VFD-driven pump stations.
Many sites in South Africa run on a mix of grid power and diesel generators, with voltage swings and frequent changeovers. Tell us your supply conditions and we design with margin on voltage, temperature rise and duty, so equipment stays protected.

Of transformer design and manufacturing experience behind every unit.
ISO 9001:2015 quality system and CE conformity under the Low Voltage Directive.
Voltages, ratings, terminals and mounting made to match your design.
Production planned around your project schedule and export shipping dates.
Yes. VA Electricals manufactures three-phase harmonic filter reactors at its works in Pune, India and supplies buyers across South Africa, including Johannesburg, Ekurhuleni, Pretoria, Durban, Dube TradePort.
Yes. Units are built for the 230 V single-phase / 400 V three-phase, 50 Hz supply used in South Africa, with reactor tuning and current rating matched to your capacitor bank and system.
Without a reactor, capacitors can resonate with harmonics from VFDs and UPS loads, causing overheating and failures. A series reactor detunes the circuit, protecting capacitors while power factor is corrected.
VA Electricals operates an ISO 9001:2015 certified quality management system and holds MSME ZED Bronze certification. Its products carry CE conformity under the Low Voltage Directive 2014/35/EU, covering chokes and reactors up to 1000 A.
Shipped by sea from Nhava Sheva to Durban, with onward delivery and air freight for urgent needs.
Yes. Tell us about voltage fluctuations, generator use and ambient temperature. We build in margin on voltage, temperature rise and duty so units stay reliable on unstable supplies.
