AOIP Equipment We Repair — By Category
AOIP Product Lines We Repair
Our engineers are trained on the full AOIP product range. Below are the major product families we service.
AOIP Three-Phase Power Analysers
Portable and fixed-installation three-phase power quality analysers for measuring voltage, current, power factor, and harmonics. Common issues include sensor drift, LCD display failure, data logging memory corruption, and communication port faults affecting plant power audits.
AOIP Harmonic Distortion Meters
Precision instruments for measuring THD (Total Harmonic Distortion) and individual harmonic components in industrial power systems. Failures typically involve sensor malfunction, filtering circuit degradation, microprocessor lockups, and inaccurate frequency measurement.
AOIP Data Logging and Recording Systems
Long-term power monitoring systems with SD card storage and real-time cloud connectivity for continuous facility energy management. Repair needs include battery depletion, data corruption, SD card interface failure, and wireless module malfunction.
AOIP Portable Field Diagnostic Kits
Handheld electrical measurement instruments for on-site commissioning, troubleshooting, and preventive maintenance in Indian manufacturing plants. Common failures include probe/clamp sensor damage, analog input channel errors, and calibration drift after environmental stress.

Common AOIP Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AOIP equipment arriving at our workshop.
- ✓Three-phase voltage sensor drift and measurement error — Extended operation in high-temperature Indian industrial environments causes sensor calibration drift. Thermal compensation circuits in AOIP analysers can fail after 5-7 years of continuous power monitoring, leading to 2-5% measurement inaccuracy affecting power audits.
- ✓LCD display segment failure and partial display blackout — High ambient humidity in tropical Indian climates causes LCD polarizer delamination and segment electrode corrosion in AOIP analysers. Repeated thermal cycling in plant environments degrades the display connector, resulting in missing numeric displays and illegible graphs.
- ✓Data logging failure and SD card read/write errors — Corrupted SD card file system, defective card detect switch, or failing power supply to the storage controller in AOIP logging modules. Sudden power cuts common in Indian industrial sites corrupt the flash memory partition, causing immediate logging shutdown.
- ✓Harmonic distortion measurement errors and THD reading inaccuracy — Input filter degradation, ADC sampling clock drift, or digital signal processor firmware corruption in AOIP harmonic metres. Plant vibration and electromagnetic interference from heavy machinery cause harmonic measurement error to exceed acceptable ±3% tolerance.
- ✓Wireless connectivity loss and Ethernet port malfunction — Corroded RJ45 connectors, failed isolation transformers, or WiFi module damage in cloud-enabled AOIP systems due to humidity ingress. Industrial EMI from VFDs and motor starters disrupts wireless signal or damages the RF front-end.
- ✓Microprocessor reset loops and instrument lockup during measurement — Power supply noise, firmware memory corruption, or SPI bus contention in AOIP analysers' main controller boards. Defective reset supervisor ICs fail to hold the processor in valid operating state, causing frequent watchdog timer resets.

Frequently Asked Questions — AOIP Repairs
Do you repair AOIP equipment across all of India?+
Yes. Synchronics Electronics repairs the complete AOIP product range — three-phase analysers, harmonic metres, data logging systems, and portable field kits. We operate pan-India service with door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all tier-2 industrial cities. Repairs are completed at our ISO-certified facility in Vadodara, Gujarat, with full calibration and testing before return.
How do you ensure AOIP power analyser measurement accuracy after repair?+
We perform complete re-calibration against traceable NIST-equivalent standards and issue measurement uncertainty certificates. Our test benches validate voltage, current, power factor, harmonic distortion, and energy measurement accuracy across the instrument's full operating range. AOIP analysers are certified to ±0.5% accuracy before dispatch, meeting Indian utility grid and industrial audit requirements.
What is the typical repair turnaround time for AOIP instruments at Synchronics?+
Standard repairs complete within 5-7 working days from receipt at our Vadodara facility. Complex faults (microcontroller reprogramming, sensor replacement, data recovery) require 10-14 days. We offer priority expedited service for critical power monitoring instruments affecting production schedules — completed within 3 days. Door-to-door service time across India typically adds 2-3 days total.
Can Synchronics recover data from corrupted AOIP data loggers?+
Yes. Our specialists use specialized flash recovery tools to retrieve logged power quality data from corrupted SD cards and internal memory in AOIP logging systems. Success rate is 85-95% depending on corruption extent. We preserve your historical power trends and generate compliant reports for energy audits. After data recovery, we repair the underlying hardware fault (storage controller, power supply, firmware) to prevent recurrence.
Do you provide AOIP calibration certificates for compliance audits?+
Absolutely. Synchronics issues calibration certificates with full measurement uncertainty analysis, traceability to NIST standards, and ISO 9001 compliance documentation. Certificates specify voltage, current, power factor, harmonic distortion, and frequency accuracy validated on our test benches. These are accepted by Indian utilities, state electricity boards, and industrial auditors for compliance proof.
How do I send my AOIP 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 AOIP 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 AOIP 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 AOIP 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.
