Frequently Asked Questions

What does electrical maintenance include?

Electrical maintenance covers inspection, testing, and servicing of power systems such as switchgear, transformers, distribution boards, and wiring. It also includes fault diagnosis, thermal scanning, and system optimisation.

What is the difference between LV and HV systems?

Low Voltage (LV) systems typically operate below 1,000V and are used in building distribution. High Voltage (HV) systems operate at higher voltages and are used for power transmission and large-scale infrastructure. Both require specialised maintenance to ensure safety and reliability.

Why is preventive electrical maintenance important?

Preventive maintenance helps identify potential faults before failure occurs, reducing the risk of downtime, equipment damage, and safety hazards such as electrical fires.

What is thermal scanning in electrical systems?

Thermal scanning (infrared thermography) detects heat abnormalities in electrical components, allowing early identification of overloaded circuits, loose connections, or failing equipment.

Do you maintain ELV systems as well?

Yes. We support Extra-Low Voltage (ELV) systems including fire alarms, communication networks, and building management systems to ensure full infrastructure reliability.

How often should electrical systems be inspected?

Inspection frequency depends on system criticality, but most facilities require scheduled maintenance at least annually, with more frequent checks for high-load or mission-critical environments.
