GE MULTILIN Equipment We Repair — By Category
GE MULTILIN Product Lines We Repair
Our engineers are trained on the full GE MULTILIN product range. Below are the major product families we service.
D90 Plus Transformer Protection Relay
Microprocessor-based numerical relay for transformer protection with differential, overcurrent, and cooling control functions. Common faults include firmware corruption, analog input module failures, and CT secondary circuit saturation issues caused by Indian grid transients.
D60 Overcurrent & Feeder Protection Relay
Compact digital relay for distribution feeder protection with directional functions and harmonic filtering. Synchronics frequently repairs D60 units with damaged surge suppression modules and loss of communication to RTU/SCADA systems.
SRTP Surge Protective Device
Transient voltage surge suppression relay protecting control circuits and instruments from lightning and switching surges. High failure rates observed in Indian industrial sites lacking proper earthing; Synchronics restores surge modules and replaces degraded varistors.
UR Series Distribution Protection Relay
Unified relay platform combining overcurrent, earth-fault, and voltage monitoring in compact format. Synchronics addresses LCD display defects, battery backup circuit failures, and sensor interface losses in UR series units.
MULTILIN Power Quality Monitor
Three-phase power quality analyzer measuring harmonics, voltage imbalance, and frequency deviation. Common repairs include sensor calibration drift, Ethernet port failures, and SD card reader malfunctions in Indian environments with poor power quality.
SRTP-6 Distance Protection Relay
Numerical distance relay for transmission line protection with quadrilateral and polygonal characteristic capability. Synchronics repairs analog input conditioning boards and resolves GPS time synchronization issues critical for pilot protection schemes.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common GE MULTILIN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GE MULTILIN equipment arriving at our workshop.
- ✓D90 relay analog input module failure — Overvoltage transients from CT saturation or lightning strikes degrade precision analog-to-digital converter circuits in Indian power systems with poor transient immunity. This causes erratic current measurements and nuisance tripping.
- ✓Communication loss between relay and RTU — Ethernet or serial port connector corrosion, RJ45 interface damage, and optical isolation chip failure in MULTILIN relays exposed to high humidity, salt air, or industrial dust. Indian coastal and humid climates accelerate connector degradation.
- ✓Firmware corruption or relay lockout state — Unexpected power loss during firmware upload, corrupted SD card in power quality monitors, or security key expiration in licensed GE MULTILIN software. Common in Indian facilities with unstable grid voltage.
- ✓CT burden and magnetizing inrush false trips — GE MULTILIN relays incorrectly configured for high CT burden or saturating secondary circuits during transformer inrush. Indian power systems often use older, high-burden CTs causing relay miscoordination.
- ✓Power supply module degradation and brownout sensitivity — Electrolytic capacitor aging in GE MULTILIN DC power supply modules under high ambient temperature (>40°C) and frequent voltage fluctuations. Indian industrial sites with poor utility power experience accelerated PSU failure.
- ✓LCD display failure and parameter visibility loss — Segment driver IC degradation, backlight LED failure, or LCD panel delamination in GE MULTILIN relays exposed to temperature extremes and vibration-induced mechanical stress in heavy equipment environments.
