HAEFELY Equipment We Repair — By Category
HAEFELY Product Lines We Repair
Our engineers are trained on the full HAEFELY product range. Below are the major product families we service.
Haefely Hipotron High Voltage Test Systems
Primary ac/dc hipot testers used in manufacturing and quality assurance for insulation breakdown testing. Common issues include high leakage current faults, voltage regulation drift, and control board failures affecting test accuracy and repeatability.
Haefely TRE/TRH Transient Recorders
Portable transient and impulse recording systems for power quality analysis and equipment condition monitoring. Frequent faults include analog channel failures, memory corruption, and USB interface communication errors.
Haefely Partial Discharge Detection Systems
Sensitive PD measurement instruments for cable, transformer, and switchgear diagnostics. Typical failures involve RF detector sensitivity loss, filter capacitor aging, and grounding system degradation affecting measurement precision.
Haefely AC/DC Voltage Sources
Heavy-duty variable voltage supplies for factory acceptance testing and on-site commissioning of high-voltage equipment. Common repair needs include transformer core saturation, output stage power semiconductor failures, and voltage regulation circuit faults.
Haefely Safety Monitoring and Earth Continuity Testers
Regulatory-compliance instruments for functional earthing, leakage current measurement, and personnel safety verification. Faults typically manifest as measurement offset errors, tripping relay stiction, and calibration drift requiring recertification.

Common HAEFELY Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HAEFELY equipment arriving at our workshop.
- ✓Hipotron high leakage current above specification limits — Moisture ingress in high-voltage transformer insulation, contaminated test leads, or degraded oil dielectric causing breakdown paths during hipot stress. This is accelerated in humid Indian monsoon environments.
- ✓Transient Recorder TRE/TRH memory corruption and data loss — Flash memory wear-out after repeated thermal cycles, power loss during data logging, or firmware update interruption affecting internal partition tables and sample buffer integrity.
- ✓Partial Discharge detector loss of RF sensitivity and noise floor elevation — Contamination of high-frequency antenna connectors, capacitor dielectric aging in narrow-band RF filters, or varistor degradation in input protection networks reducing signal-to-noise ratio below detection threshold.
- ✓AC/DC voltage source output regulation drift and unstable meter readings — Aging feedback capacitors in regulation feedback loop, thermal drift in precision voltage divider resistors, or saturation in output transformer secondary winding from prior voltage spike exposure.
- ✓Safety continuity tester relay chatter and intermittent tripping — Relay contact oxidation or arcing from repeated switching cycles, spring fatigue affecting contact pressure, or control circuit noise from inadequate EMI filtering in adjacent high-voltage equipment.
- ✓Hipotron/VS transformer primary winding short circuit and core saturation — Insulation breakdown from voltage surge transients, manufacturing defect in winding insulation, or excessive ambient heat in Indian factory environments exceeding cooling capacity during continuous high-stress testing.

Frequently Asked Questions — HAEFELY Repairs
Do you repair Haefely equipment anywhere in India?+
Yes. Synchronics repairs the full Haefely product range — high-voltage test systems, transient recorders, partial discharge detectors, voltage sources, and safety monitoring equipment. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Kolkata, and all other cities. All repairs are performed at our main facility in Vadodara, Gujarat, with fastest turnaround in the industry.
Can Synchronics recalibrate Haefely hipot testers to regulatory compliance standards?+
Absolutely. Our calibration laboratory is equipped with Haefely reference standards and traceability to national standards. We perform full hipot system recertification including voltage accuracy, current measurement, timing calibration, and leakage current limits. All repairs come with ISO 17025 calibration certificates accepted by Indian power utilities, cable manufacturers, and regulatory auditors.
What is the typical turnaround time for Haefely high-voltage test system repair?+
Most Hipotron and voltage source repairs are completed within 5-7 working days. Complex transformer rewinding or partial discharge system realignment may extend to 10-14 days. We prioritize emergency repairs for utilities and manufacturers facing production downtime — contact our emergency hotline for expedited handling. Door pickup and delivery included across India.
Does Synchronics have genuine Haefely spare parts in stock?+
Yes. We maintain an active inventory of common replacement modules, capacitors, relays, transformers, and RF components for Hipotron, TRE/TRH, and PD detection systems. We also source hard-to-find components directly from Haefely Switzerland. All repairs use original-spec parts ensuring your equipment meets manufacturer performance standards and warranty compliance.
Can you repair Haefely partial discharge systems used for cable and transformer diagnostics?+
Yes, we specialize in Haefely PD analyzer repair and recalibration. Our technicians diagnose antenna sensitivity loss, RF filter degradation, and measurement offset errors. We recalibrate PD systems using certified reference signals and restore noise floor performance, critical for accurate cable fault detection in Indian utility networks and renewable energy substations.
How do I send my HAEFELY 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 HAEFELY 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 HAEFELY 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 HAEFELY 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.
