DRANETZ Product Lines We Repair
Our engineers are trained on the full DRANETZ product range. Below are the major product families we service.
Dranetz 4500 Portable Power Analyser
The 4500 is a compact three-phase power quality analyser used for field measurement of voltage, current, power factor, and harmonics. Common issues include sensor offset drift, LCD display fading, measurement accuracy degradation, and battery contact corrosion affecting real-time logging.
Dranetz 6000 Advanced Power Quality Monitor
Three-phase recorder with waveform capture, transient detection, and long-term monitoring capability. Typical faults include SD card compatibility issues, Ethernet port failure, clock battery depletion, and relay output card malfunction affecting data logging integrity.
Dranetz 7000 Electrical Safety Analyser
Portable tester combining power quality measurement with electrical safety testing (ground resistance, insulation, continuity). Repair includes probe calibration, measurement module replacement, safety certification re-validation, and firmware restoration.
Dranetz PWRview Data Logger
Compact single- or three-phase data logger for unattended power monitoring. Common failures are memory card interface faults, communication port degradation, time synchronisation errors, and transformer lead breakage in high-vibration factory environments.
Dranetz Harmonic Probe & Sensor Modules
Current and voltage sensors, transformer modules, and multiplier packs used with Dranetz analysers. Typical issues include sensor coil opens, calibration drift, mechanical connector corrosion, and electromagnetic shielding degradation affecting measurement stability.

Common DRANETZ Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DRANETZ equipment arriving at our workshop.
- ✓Display fading and backlight failure — Dranetz analysers often experience LCD degradation after 5-7 years of field use, especially in harsh ambient conditions common to Indian manufacturing plants. Backlight LED failure reduces readability and operator confidence in real-time measurements.
- ✓Measurement accuracy degradation and sensor offset drift — Dranetz current transformer (CT) and voltage probe sensors develop calibration drift over time due to thermal cycling and mechanical stress from frequent site-to-site transport. This causes voltage and power readings to drift 1-3%, failing compliance verification.
- ✓Data logger SD card and memory interface failure — Dranetz PWRview and 6000-series loggers often suffer card slot corrosion and controller board contact failures due to humidity ingress in Indian climate. This prevents data download and triggers 'Card Not Recognized' errors on startup.
- ✓Ethernet and serial communication port malfunction — Dranetz 6000 and 7000 series monitors used in networked power quality monitoring setups experience RJ45 jack damage, failed line drivers, and firmware USB communication errors when moving between legacy Windows systems and modern IT infrastructure.
- ✓Battery and clock circuit failure causing time loss — Dranetz analysers rely on button-cell backup batteries for real-time clock and configuration memory. After 3-5 years, these batteries deplete, causing the unit to lose timestamp and stored settings, rendering long-term logging unusable for trend analysis.
- ✓Probe connector corrosion and measurement lead breakage — Field-mounted Dranetz current and voltage probes corrode at BNC and 4mm banana connectors in humid Indian industrial environments. Mechanical stress and vibration from connected machinery cause internal probe wire breaks, resulting in open-circuit and no-signal faults.

We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major cities. All repairs are processed in our Vadodara, Gujarat facility with turnaround of 5-7 working days.
Does Synchronics recalibrate Dranetz analysers to international standards?+
Yes. Synchronics performs full re-calibration of Dranetz 4500, 6000, and 7000 series using NABL-accredited reference standards and traceable measurement equipment. We issue calibration certificates valid for audit, compliance, and regulatory reporting. Calibration interval is typically 12-24 months depending on field usage intensity.
What is the typical turnaround time for Dranetz power analyser repair?+
Standard repairs (sensor replacement, firmware update, connector repair) take 5-7 working days. Urgent calibration-only requests can be completed in 2-3 days. Major board-level repairs may extend to 10-14 days. We prioritize utilities and mission-critical power quality monitoring installations with expedited scheduling.
Can Synchronics repair Dranetz analysers with measurement accuracy issues below 0.5%?+
Yes. Our engineers use precision test benches to restore Dranetz measurement accuracy to factory specifications (typically 0.2-0.5% for voltage and current). We test across the full operating range, validate power factor and harmonic calculations, and provide measurement uncertainty certificates.
Do you supply replacement Dranetz probes, transformers, and sensor modules?+
Yes. Synchronics stocks OEM Dranetz current transformers (CP-4500, CP-6000), voltage probes (VM-7000), and signal conditioning modules. We also supply probe cables, connector assemblies, and battery packs. Lead time is typically 3-5 days for in-stock items; sourcing overseas spares takes 2-3 weeks.
How do I send my DRANETZ 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 DRANETZ 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 DRANETZ 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 DRANETZ 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.
