TRABO Equipment We Repair — By Category
TRABO Product Lines We Repair
Our engineers are trained on the full TRABO product range. Below are the major product families we service.
TRABO Isolation Transformers
Single-phase and three-phase isolation transformers for EMI suppression, equipment protection, and phase-splitting applications. Common faults include primary-secondary winding insulation breakdown, core magnetization loss, and thermal damage from sustained overload or harmonic distortion.
TRABO Autotransformers
Step-up and step-down autotransformers for voltage regulation in CNC machines, industrial ovens, and laboratory equipment. Prone to tap selector wiper oxidation, winding short circuits under transient spikes, and core lamination separation at high frequencies.
TRABO Three-Phase Power Transformers
Heavy-duty distribution and machine-tool transformers for 3-phase industrial feeds. Repairs address oil cooling system failures, bushing tracking, copper loss overheating, and vector group mismatch causing phase shift errors in synchronous machine applications.
TRABO Phase Converter Systems
Rotary and static phase converters for single-phase to three-phase conversion in Indian plants lacking three-phase mains. Failures include capacitor bank degradation, winding overheating, and phase angle stability loss under variable load conditions.
TRABO Instrument Transformers (Current & Voltage)
CT and VT transformers for metering, protection relays, and power quality monitoring in Indian substations and factory distribution boards. Common failures: secondary winding saturation, insulation oil degradation, and ferroresonance under fault conditions.

Common TRABO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in TRABO equipment arriving at our workshop.
- ✓Primary to secondary winding insulation breakdown — TRABO transformer insulation degrades due to moisture ingress in humid Indian climates, age, or transient overvoltage spikes from switchgear operation. Moisture reduces dielectric strength, leading to creeping discharge and eventual high-voltage flashover between windings.
- ✓Core lamination hot-spot overheating — Eddy current losses increase when TRABO core laminations separate or corrode due to moisture, vibration, or mechanical stress. In industrial environments with high harmonic content, core heating intensifies, eventually causing oil decomposition and visible smoke.
- ✓Winding turn-to-turn short circuit — Physical damage during transport, vibration, or insulation abrasion between turns in TRABO coils causes internal shorts. In Indian factories with dust, vibration from adjacent machinery accelerates enamel coating wear. High-fault-current events can also trigger turn-to-turn failures.
- ✓Tap selector contact oxidation and poor connection — TRABO autotransformers with multiple voltage taps suffer corrosion of wiper contacts in dusty, humid Indian plants. Oxidation increases contact resistance, causing voltage drop, localized heating, and erratic voltage selection. Sulfur-bearing air pollutants accelerate corrosion.
- ✓Oil cooling system blockage and overtemperature — TRABO large power transformers rely on oil circulation for cooling. Sediment, sludge buildup, and clogged oil ducts restrict heat transfer. In Indian plants operating 24/7 in high-temperature environments, thermal stress accelerates oil oxidation and blockage, raising winding temperature to dangerous levels.
- ✓Bushing tracking and carbonization — TRABO transformer bushings exposed to high humidity, salt spray (coastal Indian plants), and pollution accumulate conductive paths on insulator surfaces. Partial discharge tracking leads to carbon traces, which eventually allow arc-over between bushing terminal and transformer tank ground.

Frequently Asked Questions — TRABO Repairs
Do you repair TRABO equipment anywhere in India?+
Yes, Synchronics repairs the full range of TRABO power transformers, isolation transformers, autotransformers, and phase converters across India. We offer PAN India pickup and delivery from major cities including Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Surat, and all tier-2 and tier-3 cities. All repairs are handled at our fully equipped facility in Vadodara, Gujarat with 180-plus trained engineers.
What TRABO transformer faults can Synchronics diagnose?+
Synchronics diagnoses winding insulation breakdown, core lamination separation, turn-to-turn shorts, tap selector oxidation, cooling system blockages, bushing tracking, and oil degradation. We use megohm testers, thermal imaging, power factor analysis, DC resistance measurement, and oil quality testing to pinpoint root causes. Once diagnosed, we provide a detailed repair report and quote.
How long does TRABO transformer repair typically take?+
Simple repairs like contact cleaning or oil replacement take 3-5 days. Winding insulation work and major oil service require 7-10 days. Complete winding rewind or core replacement can take 2-3 weeks depending on transformer size and complexity. Synchronics communicates timelines upfront and keeps customers updated throughout repair.
Can you repair TRABO isolation transformers used in CNC machine tool shops?+
Absolutely. TRABO isolation transformers are widely used in Indian CNC and precision machine shops for EMI suppression and equipment protection. We repair primary-secondary insulation faults, core heating issues, and winding shorts common in these applications. We test repaired transformers under load to ensure they meet CNC precision power requirements before shipment back to the shop.
Does Synchronics certify TRABO transformer repairs with test certificates?+
Yes. All TRABO repairs include full testing: megohm insulation resistance, winding continuity, ratio testing, thermal imaging, and oil analysis where applicable. Synchronics provides a detailed test certificate documenting pre-repair condition, repair actions, and post-repair performance. This ensures compliance with Indian electrical safety standards and gives customers confidence in reliability.
How do I send my TRABO 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 TRABO 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 TRABO 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 TRABO 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.
