BIS Repair Services India
BIS (Bureau of Indian Standards) is India's national standards body established post-independence to formulate, adopt and implement Indian Standards across all sectors except electrical and atomic energy. As the custodian of standardization in India, BIS sets quality benchmarks for industrial electronics, safety protocols, and performance metrics that manufacturers and equipment suppliers must comply with. BIS certification is mandatory for numerous product categories in Indian industry.

Synchronics Electronics specializes in repairing and servicing industrial equipment that meets BIS compliance standards. While BIS itself does not manufacture industrial electronics like drives or PLCs, our expertise lies in maintaining, troubleshooting, and repairing equipment certified under BIS standards — from electrical safety components to control systems. We ensure your repaired equipment re-enters service meeting all applicable BIS quality requirements and safety certifications mandated for Indian industrial operations.

BIS Equipment We Repair — By Category
BIS Product Lines We Repair
Our engineers are trained on the full BIS product range. Below are the major product families we service.
BIS-Certified Power Distribution Equipment
Switchgear, circuit breakers, and distribution panels certified under IS 8623 and IS 9303. Common issues include contact erosion, tripping failures, and insulation degradation in tropical Indian environments.
BIS-Compliant Safety Control Systems
Emergency stop devices, safety relays, and interlocking systems meeting IS 13149 (Safety of Machinery). Failures typically involve relay coil burnout, contact sticking, and logic circuit faults in harsh factory conditions.
BIS-Certified Cable and Wiring Systems
Industrial cables, connectors, and terminations meeting IS 694 and IS 1554 specifications. Common defects include insulation breakdown, copper oxidation, and loose crimped terminals in high-humidity Indian plants.
BIS-Approved Control Transformers and Reactors
Single-phase and three-phase transformers meeting IS 2026 for industrial use. Typical failures include core saturation, winding insulation failure, and thermal runaway due to overloaded Indian grid conditions.
BIS-Standard Electrical Fuses and Overload Protection
HRC fuses, MCBs, and thermal overload relays certified under IS 8286 and IS 8828. Common issues: nuisance tripping, delayed response, and coordination failures in variable-load applications.

Common BIS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BIS equipment arriving at our workshop.
- ✓Contact pitting and arc damage in BIS-certified switchgear — Extended exposure to high-current switching cycles in Indian industrial environments. Moisture ingress and atmospheric pollution (dust, salt spray in coastal regions) accelerate contact erosion, causing increased contact resistance and voltage drop.
- ✓Insulation breakdown in power cables and bus ducts — Moisture absorption, mechanical damage, and thermal stress in high-ambient-temperature plants (common in Indian summers exceeding 45°C). Rodent damage and chemical contamination in chemical/pharma plants deteriorate insulation quickly.
- ✓Relay coil burnout and stuck contacts in safety control systems — Voltage surges from Indian grid instability, inadequate suppression diodes, and thermal stress from continuous operation in non-air-conditioned control rooms. Humidity causes moisture corrosion of coil windings and contact surfaces.
- ✓Thermal runaway and core saturation in control transformers — Overloading due to inadequate load distribution, harmonics from variable frequency drives (VFDs), and poor cooling in confined Indian panel designs. Loose laminations due to vibration exacerbate heat buildup.
- ✓Nuisance tripping of MCBs and thermal overload relays — Inrush current spikes from motor starting, harmonic distortion from non-linear loads, and ambient temperature variations in Indian seasonal climates affecting bimetallic strips and electronic trip units.
- ✓HRC fuse non-operation and slow response times — Corrosion of fuse element and contacts due to moisture and salt-laden air in coastal Indian plants. Dust accumulation reduces heat dissipation, causing elevated fuse temperature and delayed melting during overload events.

Frequently Asked Questions — BIS Repairs
Do you repair BIS-certified equipment and maintain compliance?+
Yes. Synchronics repairs all BIS-compliant industrial equipment — switchgear, safety controls, transformers, cables, fuses, and protection devices. Every repair is tested and validated against applicable IS codes (IS 8623, IS 13149, IS 2026, IS 1554, etc.) to ensure your equipment retains BIS certification. We maintain complete repair documentation for compliance audits and regulatory inspections across Indian manufacturing facilities.
What is your turnaround time for BIS-certified switchgear repair in India?+
Standard turnaround is 10-14 days for switchgear repairs from receipt in Vadodara. We prioritize emergency repairs on high-voltage equipment for critical production lines — expedited service available within 5-7 days. Synchronics operates pan-India pickup from major cities (Mumbai, Delhi, Bangalore, Chennai, Pune, Hyderabad) with courier return. Lead time depends on parts availability and damage complexity; we provide upfront estimates after initial inspection.
How do you ensure repaired equipment meets current BIS standards?+
Synchronics employs certified test engineers who validate all repairs against the latest IS codes applicable to your equipment category. We use calibrated instruments (megohm meters, current clamps, thermal imagers) traceable to NPL India standards. Each repair includes functional testing, safety verification, and calibration records — essential for Indian industrial compliance audits, ESM audits, and statutory inspections by boiler/machinery inspectorates.
Can you repair equipment with BIS certification expired or pending renewal?+
Absolutely. Synchronics restores equipment to full BIS compliance even if certifications have lapsed. We conduct comprehensive testing per all applicable IS standards, document repairs with before/after readings, and provide test certificates that support your facility's re-certification process with BIS or your notified body. Many Indian plants rely on our repair and certification support during scheduled maintenance shutdowns.
What regions in India do you serve for BIS equipment repairs?+
Synchronics provides pan-India service with door pickup from all major industrial hubs: Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all tier-2 cities. All repairs are processed in our ISO-certified facility in Vadodara, Gujarat. We handle domestic courier logistics, reducing downtime for your BIS-compliant equipment. Same-facility repair ensures quality consistency and faster turnaround across Indian industrial sectors.
How do I send my BIS 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 BIS 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 BIS 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 BIS 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.
