LT System Maintenance

LT (Low Tension) system maintenance is essential for ensuring the safe, reliable, and efficient operation of low-voltage electrical distribution systems. Regular maintenance helps prevent power failures, equipment damage, and electrical hazards while extending the life of LT panels and connected equipment.

At GGS Engineering Service, we provide comprehensive LT system maintenance services designed to keep your electrical infrastructure stable, compliant, and dependable.

LT System Maintenance

Scope of LT System Maintenance Services

Routine Inspection

Periodic inspection of LT panels, switchboards, breakers, busbars, cables, and connections to identify overheating, wear, corrosion, loose joints, or abnormal conditions.

Cleaning & Housekeeping

Cleaning of LT panels and components to remove dust, moisture, and contaminants that can cause insulation failure and overheating.

Tightening of Electrical Connections

Checking and tightening of terminations, joints, and busbar connections to prevent arcing, voltage drops, and power losses.

Testing of Protective Devices

Functional testing of MCBs, MCCBs, relays, contactors, and protection devices to ensure correct operation and coordination.

Insulation Resistance & Continuity Testing

Measurement of insulation resistance and continuity to detect leakage currents, insulation degradation, and potential short circuits.

Thermal Scanning (Infrared Thermography)

Thermal imaging of LT panels and connections to identify hotspots and early-stage faults without interrupting operations.

Troubleshooting & Corrective Actions

Identification and rectification of electrical faults such as tripping issues, load imbalance, and component failures.
