DOBLE LEMKE Product Lines We Repair
Our engineers are trained on the full DOBLE LEMKE product range. Below are the major product families we service.
Oil Analysis & Monitoring Systems
Portable and laboratory-based transformer oil diagnostic instruments measuring moisture, dissolved gas, acid number, and breakdown voltage. Common issues include sensor drift, moisture ingress into optical paths, and calibration loss after extended field use.
Transformer Condition Assessment Tools
Handheld and bench-top equipment for measuring insulation resistance, dielectric loss (tan delta), frequency response analysis, and winding resistance. Repairs often involve sensor calibration, connector corrosion, and internal measurement circuit faults.
Dissolved Gas Analysis (DGA) Modules
Specialized chromatography-based systems detecting hydrogen, methane, ethylene, ethane, and other fault gases in transformer oil. Prone to thermal drift in column ovens, detector response degradation, and gas line contamination in humid Indian climates.
Predictive Health Monitoring Software & Interfaces
Windows-based data acquisition and trending software for remote transformer health monitoring, alarm generation, and historical record management. Issues include database corruption, sensor communication loss, and firmware version incompatibility.
Portable Field Test Kits
Lightweight, ruggedized diagnostic bundles for on-site transformer assessment combining oil sampling, quick test capability, and parameter logging. Susceptible to impact damage, humidity ingress, and battery management faults in field deployment.
Calibration & Reference Standards
Precision reference materials, calibration gases, and verification liquids ensuring measurement accuracy. Degradation and expiry are common; Synchronics provides replacement sourcing and recalibration validation.

Common DOBLE LEMKE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DOBLE LEMKE equipment arriving at our workshop.
- ✓Oil analysis sensor drift and accuracy loss — Doble Lemke optical and electrochemical sensors degrade due to prolonged exposure to humid Indian climate, dust contamination in field environments, and inadequate sensor protection during transport. Measurement inaccuracy exceeds +/- 5% from factory baseline.
- ✓DGA thermal column overshoot and detector instability — Temperature control circuits in Doble Lemke chromatography columns drift due to aged heating elements, faulty PID loop tuning, and thermal sensor contact degradation in high-temperature zone. Column temperature variation exceeds +/- 2 degrees Celsius, causing peak resolution failure and gas identification errors.
- ✓Moisture sensor reading oscillation and zero drift — Doble Lemke capacitive moisture probes suffer corrosion and electrochemical drift when exposed to high-humidity Indian workshop and field conditions. Connector pin oxidation at sensor terminations causes intermittent signal dropout and floating baseline readings.
- ✓Tan delta measurement unit phase shift and magnitude error — Doble Lemke high-voltage test bridges accumulate phase errors due to component aging in coupling capacitors and precision resistor networks. Cable shield aging and HV connector contamination introduce leakage currents that distort loss angle measurement, especially critical for transformer insulation assessment above 50 kV.
- ✓Frequency response analysis (FRA) noise floor elevation and signal loss — Doble Lemke FRA modules experience RF amplifier degradation and mixer non-linearity due to temperature cycling in Indian climatic extremes. Shield integrity loss in coaxial connections and aging operational amplifiers cause signal-to-noise ratio degradation and low-frequency response masking.
- ✓Software interface database corruption and communication timeout — Doble Lemke Health Suite and monitoring gateways experience database index failure and memory leak under continuous operation in large utility deployments. Network communication timeouts occur due to aging Ethernet interface modules and protocol stack instability under heavy data logging loads.

Frequently Asked Questions — DOBLE LEMKE Repairs
Do you repair Doble Lemke equipment anywhere in India?+
Yes. Synchronics repairs the full Doble Lemke product range — oil analysis systems, transformer condition monitoring equipment, DGA modules, portable field kits, and diagnostic software interfaces. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other cities. Single facility in Vadodara, Gujarat with direct access to Doble Lemke technical specifications and spare part sourcing.
Why is my Doble Lemke dissolved gas analyzer showing inconsistent DGA results between field tests?+
DGA inconsistency typically indicates thermal column drift, detector baseline shift, or sample contamination during collection. Synchronics performs full chromatography system validation — column temperature calibration, FID detector sensitivity restoration, and gas line purge validation. We run multi-component test gas mixtures and certify measurement repeatability. Common root cause is aged heating element in thermal control zone; we replace and re-validate column performance per factory specification.
Can Synchronics calibrate Doble Lemke moisture sensors and oil analysis probes to factory standards?+
Yes. Synchronics maintains certified calibration reference standards for all Doble Lemke sensor types — moisture probes, acid number electrodes, breakdown voltage electrodes, and optical gas sensors. We perform point-by-point calibration across manufacturer specifications, issue NIST-traceable certificates, and validate zero-point stability and repeatability. Turnaround is 7-10 business days for sensor restoration; we source genuine Doble Lemke replacement cartridges when calibration cannot restore accuracy.
Our Doble Lemke Health Suite software shows communication timeout errors with field monitoring gateways — what is the typical repair approach?+
Communication timeout in Doble Lemke monitoring systems is usually caused by aging Ethernet interface modules, firmware version mismatch, or database index corruption. Synchronics performs gateway hardware diagnostics, replaces faulty network interface cards, applies latest firmware patches from Doble Lemke, and repairs corrupted sensor configuration databases. We validate stable bi-directional communication, perform extended 72-hour stability testing, and restore full remote monitoring functionality for utilities tracking transformer fleet health.
What is the typical repair cost and turnaround time for Doble Lemke oil analysis equipment at Synchronics?+
Repair costs vary by equipment type and fault severity. Oil analysis systems typically cost Rs. 15,000 to Rs. 45,000 depending on sensor replacement needs and calibration complexity. DGA modules and FRA units range Rs. 25,000 to Rs. 60,000. Standard turnaround is 10-14 business days from receipt. We provide free diagnostic assessment and written quotation before repair. Emergency expedited repairs available for critical utility and industrial applications — 48-hour turnaround at 25% premium. All repairs include 12-month parts warranty and certified test documentation.
How do I send my DOBLE LEMKE 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 DOBLE LEMKE 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 DOBLE LEMKE 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 DOBLE LEMKE 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.
