Q & A

What is the primary role of equipment maintenance in the electricity supply system?

The primary role of equipment maintenance is to support the quality and reliability of electricity supply to consumers by ensuring that equipment continues to operate according to its design functions and characteristics.

What safety gear should be worn before performing inspections in the substation?

Before performing inspections, personnel should wear complete Personal Protective Equipment (PPE), including wearpacks, safety shoes, gloves, and helmets.

What is the purpose of a Level 1 substation inspection?

The purpose of a Level 1 substation inspection is to check the condition of the equipment, including relays, control panels, and other components, ensuring they are functioning normally and meeting safety standards.

What is checked during a Level 1 inspection of the relay in the transmission PAN?

During a Level 1 inspection of the relay, the functionality of the overcurrent and distance relays is checked, including indicators like LED event alarms to ensure they are operating correctly.

Why is the condition of the PMT drive mechanics important during inspections?

The condition of the PMT drive mechanics, particularly the spring indicator, is important to ensure that it is in a normal or charge condition for proper operation.

What should be checked regarding the control cabinet during a Level 1 inspection?

The control cabinet should be checked to ensure the door seal is intact, the cabinet is clean, not corroded, and the heater is working properly. Additionally, there should be no unusual odors, such as the smell of burning.

What is the significance of inspecting the SF6 arc damping media?

Inspecting the SF6 arc damping media is crucial to ensure that it is in the normal condition range, as indicated by the SF6 indicator, to maintain the proper functioning of the substation equipment.

What does a Level 1 weekly inspection of the PMT involve?

A Level 1 weekly inspection of the PMT involves checking the condition of the PMT counter, the physical condition of the insulator, and ensuring that the structure and foundation of the PMT are in good condition, without cracks, corrosion, or bends.

How is the oil level checked during a Level 1 inspection of the CT?

During a Level 1 inspection of the CT, the oil level is checked to ensure it is at the maximum normal condition. If the oil level is found to be low, further inspections are carried out to check for leaks or seepage.

What is the purpose of a quarterly inspection of the lightning arrester?

The quarterly inspection of the lightning arrester involves checking its physical condition, ensuring proper grounding, and listening for any abnormal Corona sound to confirm its proper functionality.
