COMET Equipment We Repair — By Category
COMET Product Lines We Repair
Our engineers are trained on the full COMET product range. Below are the major product families we service.
COMET Capacitor Banks
Three-phase power factor correction capacitors used in motor circuits and distribution panels. Common issues include dielectric breakdown, blown fuses within capacitor units, and internal short circuits causing nuisance trips in switchgear.
COMET Harmonic Filter Units
Tuned LC filter assemblies designed to suppress harmonic distortion in variable frequency drive systems and non-linear loads. Faults include inductor saturation, capacitor unit failures, and resonance frequency drift due to aging.
COMET Detuned Filters
Passive filter banks preventing nuisance tripping caused by soft-starter and VFD harmonic injection. Issues arise from capacitor aging, inductor winding faults, and impedance mismatch under high ambient temperatures.
COMET Control and Protection Modules
Electronic controllers managing capacitor bank switching, voltage regulation, and fault detection. Common failures include relay coil burnout, capacitive sensor drift, and DSP firmware corruption under thermal stress.
COMET RF and Vacuum Capacitors
Specialized high-frequency capacitors for broadcast, medical X-ray, and industrial heating applications. Prone to vacuum seal leakage, electrode arc-over under overvoltage transients, and ceramic insulation micro-cracks.

Common COMET Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COMET equipment arriving at our workshop.
- ✓Capacitor dielectric breakdown and unit rupture — Overvoltage transients from grid surges or improper DC bus charging in power factor correction circuits exceed rated voltage margins. Thermal aging of film insulation accelerates breakdown, especially in high-ambient Indian textile and steel plants operating 24/7.
- ✓Harmonic filter resonance and unexpected impedance rise — Grid impedance changes from nearby utility upgrades or additional VFD installations shift filter tuning frequency away from target harmonic order. COMET filter inductor core saturation under heavy load further degrades filtering performance.
- ✓Control module relay and contactor malfunction — COMET capacitor bank switching relays suffer contact erosion from repeated inrush current switching, especially in plants with frequent power cycling. Dust ingress in relay contacts causes intermittent contact resistance and nuisance false-trips.
- ✓Voltage regulation error and over-reactive compensation — COMET VR-SOFT and VARLOGIC control modules experience sensor calibration drift as temperature sensors age in hot Indian industrial environments. DSP firmware bugs cause improper capacitor step-switching logic leading to voltage overshoot.
- ✓Blown fuses and internal capacitor unit open-circuit — Manufacturing defects in COMET capacitor internal fuse elements combined with momentary overload events cause premature fuse rupture. Plant single-phase load imbalances force capacitor units to carry disproportionate current.
- ✓RF capacitor vacuum seal leakage and performance degradation — Extended thermal cycling in broadcast transmitter and medical X-ray room installations causes micro-cracks in vacuum seal ceramics. Vibration from machinery and weak braze joints accelerate hermeticity loss.

Frequently Asked Questions — COMET Repairs
Do you repair COMET capacitor banks and harmonic filters anywhere in India?+
Yes. Synchronics is an authorized COMET repair center for the entire Indian subcontinent. We repair COMET power factor correction systems, harmonic filter units, and RF capacitors from our Vadodara facility. We offer same-day courier pickup from Delhi, Mumbai, Pune, Ahmedabad, Chennai, Hyderabad, Kolkata, and all tier-2 industrial cities. Standard turnaround is 7-10 working days with full warranty.
What is the difference between COMET detuned filters and standard harmonic filter designs?+
COMET detuned filters (HFD series) are specifically designed to prevent nuisance tripping when soft-starters or small VFDs are installed on the same busbar as the capacitor bank. Unlike standard tuned filters, COMET HFD units use an additional series reactor that shifts the resonant frequency away from 5th and 7th harmonic frequencies generated by drive electronics. Synchronics tests both filter types and recommends the correct topology based on your plant's load profile.
How do you diagnose COMET control module (VARLOGIC) failures?+
Our technicians use dual approach: analog multimeter testing of relay coil continuity and voltage sensor output, plus DSP firmware diagnostic mode access using RS-485 communication. We load COMET's proprietary diagnostic software to read error memory codes (e.g., 'E-07 Voltage Out of Range') and identify whether the fault is sensor-related or firmware-based. For repairable faults we recalibrate sensors; for firmware corruption we reprogram EEPROM.
What warranty and support do you offer on repaired COMET equipment?+
All Synchronics COMET repairs carry 24-month comprehensive warranty covering parts and labor. We maintain emergency hotline support for critical industrial failures. If a repaired COMET capacitor bank fails within warranty, we replace it free and cover reinstallation labor. For spare parts, we stock common COMET MKP capacitor units and relay modules to minimize downtime.
Can Synchronics perform on-site COMET system commissioning and testing after repair?+
Yes. We offer on-site services across Indian industrial regions. Our field engineers bring power quality analyzers to measure harmonic distortion (THD), reactive power compensation, and voltage stability before and after repair. We verify three-phase load balance, perform capacitor bank switching transient checks, and provide compliance documentation for utilities and plant management. Premium service available for mission-critical power factor correction systems.
How do I send my COMET 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 COMET 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 COMET 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 COMET 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.
