CABUR Equipment We Repair — By Category
CABUR Product Lines We Repair
Our engineers are trained on the full CABUR product range. Below are the major product families we service.
VARSET Automatic Power Factor Correction
VARSET series provides thyristor-switched capacitor bank technology for automatic reactive power compensation. Common issues include thyristor module failures, capacitor element breakdown, and microprocessor control board faults that cause banks to stop responding to load changes.
VARDYNO Detuned Harmonic Filters
VARDYNO detuned harmonic filter units combine capacitor banks with detuning reactors to suppress 5th, 7th, and 11th harmonics in rectifier and variable frequency drive loads. Failures occur in reactor windings, capacitor element fatigue, and thermal protection cutouts.
VARBOX Compact PFC Units
VARBOX is a compact fixed or switched capacitor enclosure for space-constrained installations in Indian textile mills and food processing plants. Issues include relay contact pitting, contactor failure, fuse blowing under transient conditions, and capacitor case leakage.
VARHARM Active Harmonic Filters
VARHARM active harmonic mitigation systems use PWM inverter technology to suppress broadband harmonics and balance phase currents in cement kiln drives and steel rolling mill VFD loads. Inverter IGBT failures, gate driver board faults, and DSP controller crashes are typical repair needs.
STATIC VAR GENERATOR (SVG)
Heavy-duty SVG systems for large Indian manufacturing plants requiring dynamic reactive power and harmonic compensation. Faults include power semiconductor failure, phase-locked loop instability, current transformer saturation, and protection relay misfunction.

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common CABUR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CABUR equipment arriving at our workshop.
- ✓VARSET capacitor bank does not respond to reactive load — Thyristor gate driver circuit failure in the switching module, or microprocessor watchdog timeout preventing bank contactor engagement during load transients. Common in plants with high harmonic distortion.
- ✓VARDYNO harmonic filter tripping on overload — Detuning reactor winding insulation degradation under sustained high harmonic current, or capacitor element dry-out from extended thermal stress in summer-loaded Indian cement plants. Filter tuning frequency drifts out of specification.
- ✓VARBOX fixed capacitor bank low voltage output after installation — Incorrect tap configuration on primary-side voltage transformer, loose capacitor terminal lugs, or internal fuse pre-blown from manufacturing defect. Plant electricians may have misidentified voltage class during commissioning.
- ✓VARHARM active filter saturated current output — PWM inverter IGBT hard fault or gate driver IC failure causing half-bridge collapse. Phase-locked loop loses grid synchronization when grid voltage sag or harmonic distortion exceeds 15% THD typical in Indian automotive welding shops.
- ✓SVG system unable to regulate reactive power under load step change — Current transformer CT primary saturation or secondary winding short-circuit preventing accurate load current feedback. Inner control loop bandwidth insufficient for plant sudden load swings from crane duty cycle or furnace on-off cycles.
- ✓CABUR capacitor bank case bulging or electrolyte weeping — Long-term aluminum electrolytic or polypropylene film capacitor degradation caused by sustained ripple current, inadequate plant cooling ventilation, or ambient temperature exceeding 45°C common in Indian textile dyeing facilities. Pressure relief valve activation preceded by capacity loss.

Frequently Asked Questions — CABUR Repairs
Do you repair CABUR equipment anywhere in India?+
Yes. Synchronics repairs the full CABUR product range — capacitor banks, harmonic filters, active power quality systems, and control modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, Nagpur, and all other cities. All repairs are performed at our main facility in Vadodara, Gujarat with 29-year track record and CABUR technical certifications.
What is the typical turnaround time for CABUR capacitor bank repair?+
Standard VARSET, VARDYNO, and VARBOX repairs take 5-7 working days including dielectric testing, capacitor element capacity verification, and control board firmware validation. Urgent PAN India express service (48-72 hours) available for critical plant outages. We maintain stock of common CABUR capacitor cells and thyristor modules to minimize lead time.
How do you test CABUR power factor capacitors before returning them?+
Synchronics tests every CABUR capacitor unit using precision ESR meters, leakage current testers, and dielectric breakdown equipment calibrated to CABUR factory specifications. We perform high-voltage AC hipot testing at 2x rated voltage, measure capacitance within 5% tolerance, and validate thermal cycling stability before release.
Can Synchronics repair CABUR VARHARM active harmonic filter IGBT modules?+
Yes. We are equipped to test, replace, and verify VARHARM inverter IGBT modules including gate driver circuits and snubber networks. All replacement semiconductors are sourced from verified Italian and European distributors and fitted with thermal interface compound. Completed units undergo full grid synchronization testing under simulated plant load conditions.
Do you provide on-site CABUR maintenance and preventive care in Indian manufacturing plants?+
Yes. Synchronics offers CABUR PFC and harmonic filter preventive maintenance contracts across India — including quarterly capacitor cell ESR trending, thermal imaging of reactors, control board battery replacement, and firmware updates. We work with major textile mills, steel plants, and cement factories on annual maintenance budgets to extend CABUR equipment life and reduce reactive power billing.
How do I send my CABUR unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a CABUR drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on CABUR repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your CABUR unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
