IESCO Product Lines We Repair
Our engineers are trained on the full IESCO product range. Below are the major product families we service.
IESCO Protection Relays
Electromechanical and microprocessor-based overcurrent, earth fault, and distance protection relays for distribution networks. Common faults include worn contacts, relay chatter, calibration drift, and firmware corruption in digital variants.
IESCO Energy Meters
Three-phase and single-phase energy meters with pulse output and communication interfaces. Repair focuses on display failures, current transformer errors, calibration loss, and RS485/Modbus communication faults.
IESCO Substation Automation Controllers
Microcontroller-based automation units for remote monitoring, load shedding, and circuit breaker control. Common issues include memory corruption, analog input faults, relay output sticking, and modem connectivity loss.
IESCO Power Quality Monitors
Three-phase voltage and current analyzers with harmonic analysis and event recording. Failures include voltage reference drift, CT saturation, SD card corruption, and display module degradation.
IESCO Industrial Switchgear Control Boards
Panel-mounted control and synchronization boards for main and bus coupler switches. Repair addresses contact corrosion, logic board failures, field device interfacing errors, and mechanical linkage wear.
Why Choose Synchronics for IESCO Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on IESCO equipment.
Fast Turnaround
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 IESCO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in IESCO equipment arriving at our workshop.
- ✓IESCO relay contact wear and chatter — Continuous switching cycles, arcing, and mechanical fatigue in electromechanical relays cause contact erosion and increased contact resistance, leading to false trip signals or failure to trip.
- ✓IESCO energy meter display blackout or segment failure — LCD pixel failure, power supply dropout in meter auxiliary circuits, or internal battery depletion in backup-powered display modules cause total or partial meter readout loss.
- ✓IESCO RTU modem connectivity timeout — Modem firmware crashes, RS485 transceiver faults, worn telephone line interfaces, or corrupted stored scripts prevent data transmission to SCADA host in remote substation applications.
- ✓IESCO protection relay calibration drift beyond tolerance — Component aging, temperature extremes in outdoor substations, and mechanical wear in analog input circuits cause pickup voltage and timing settings to drift beyond ±2-5% tolerance bands.
- ✓IESCO switchgear control board logic fault during load transfer — Contactor relay coil burnout, blown logic gate ICs, corroded transformer terminals, or firmware bugs prevent proper sequencing during automatic bus coupler switching operations.
- ✓IESCO power quality monitor SD card data loss — Repeated power interruptions during write cycles, faulty SD card controller IC, or incompatible firmware versions cause file system corruption and loss of historical harmonic and transient event data.

Frequently Asked Questions — IESCO Repairs
Do you repair IESCO equipment anywhere in India?+
Yes. Synchronics repairs IESCO protection relays, energy meters, substation controllers, and power quality monitors across India. We offer PAN India door-to-door pickup service from major cities including Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all other industrial regions. All repairs are handled at our Vadodara, Gujarat facility with 180+ trained engineers.
What is the typical repair turnaround time for IESCO protection relays?+
Standard IESCO electromechanical relay repairs take 3-5 working days including contact replacement, mechanism cleaning, and calibration. Numeric relay repairs with firmware issues may take 5-7 days if reprogramming or parts ordering is required. We offer express service for critical substation applications — contact our technical team for same-facility turnaround estimates.
Can Synchronics repair IESCO RTU controllers that have lost RS485 communication with our SCADA system?+
Absolutely. IESCO RTU communication faults are our specialty. We diagnose modem hardware failures, repair or replace RS485 transceiver ICs, reconfigure serial communication parameters, reprogram stored dial-up scripts, and validate live connectivity to your SCADA host before returning the unit. We support all IESCO RTU modem types and protocols used in Indian substations.
Do you issue calibration certificates for repaired IESCO energy meters and protection relays?+
Yes. Synchronics issues detailed calibration certificates for all IESCO meters and relays we repair. Certificates include pre-repair and post-repair characteristic measurements, dated test results, and compliance notes. These certificates support audit and regulatory compliance requirements for Indian power utilities and large industrial consumers.
What should I do if my IESCO substation controller shows a 'watchdog timeout' error on startup?+
Watchdog timeout errors typically indicate firmware corruption, RAM failure, or internal clock circuit faults in IESCO controllers. Do not attempt repeated resets as this may corrupt data logs. Ship the unit to Synchronics immediately — we will perform firmware reflashing, diagnose and replace faulty memory or oscillator components, and test the controller under simulated operating conditions before return.
How do I send my IESCO 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 IESCO 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 IESCO 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 IESCO 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.
