Upskilling Operator GI : IL 1 Bay Trafo (ULTG Bima)

Summary

In this video, Mimin provides an overview of a Level 1 equipment inspection at a substation. The process involves checking crucial components like the circuit breaker mechanical cabinet, insulators, SF6 gas levels, and MCBs. Inspectors also check the current transformer, lightning arresters, disconnecting switch, MK cabinet, and power transformer, ensuring proper oil levels, fan performance, and leak prevention. The inspection also covers ensuring the cleanliness of the switchyard and addressing animal access concerns. This detailed inspection routine is vital for maintaining equipment safety and preventing failures in the substation.

Takeaways

• 😀 The video discusses the main substation operator's role in performing Level 1 equipment inspections.
• 😀 The Power Inspect application is used to carry out various inspection tasks.
• 😀 The first inspection task involves checking the circuit breaker mechanical cabinet for cleanliness and foreign objects.
• 😀 Inspecting the insulator and SF6 gas level is part of the equipment assessment process.
• 😀 The MCBs in each equipment cabinet must be checked to ensure they are in the 'on' position.
• 😀 Oil level and potential leaks in current transformers are inspected during the procedure.
• 😀 The lightning arrester's counter and leakage current are examined to ensure safety.
• 😀 Disconnecting switches are checked for knife insulator and driving mechanics condition.
• 😀 Each MCB in the MK cabinet should be verified to ensure it is on and free from animal access.
• 😀 Power transformer inspections involve checking oil temperature, fan performance, and oil level in the conservator.
• 😀 Ensuring there are no abnormal sounds or leaks in the power transformer, along with inspecting silicone gel valves and cable hole closures, is crucial for proper maintenance.

Q & A

What is the main focus of the inspection activity described in the script?

The main focus of the inspection activity is the level 1 equipment inspection of the Bay transformer, which involves various checks on components such as circuit breakers, insulators, and power transformers.

What application is used for the inspection process?

The Power Inspect application is used for conducting the inspection activities.

What are the key aspects to check in the circuit breaker mechanical cabinet during the inspection?

The key aspects to check include ensuring that the cabinet is clean, free from foreign objects, and that there are no ceilings obstructing the cabinet.

What are the checks performed on the insulator during the inspection?

The insulator is checked for its condition, and the SF6 gas level is also verified during the inspection.

What should be inspected in the equipment cabinets during the inspection?

Each MCB in the equipment cabinet should be in the 'on' position, and the oil level and any potential leaks on the current transformer should be checked.

What components are checked to ensure the lightning arrester is functioning properly?

The counter and leakage current on the lightning arrester are checked to ensure it is functioning correctly.

How is the disconnecting switch checked during the inspection?

The knife insulator and the driving mechanics of the disconnecting switch are inspected to ensure proper operation.

What is the purpose of inspecting the MK cabinet?

The MK cabinet is inspected to ensure that each MCB is on and that there is no animal access from open holes in the cabinet.

What are the key points to check on the power transformer?

Key points to check on the power transformer include the oil temperature, fan performance, oil level in the conservator, any abnormal sounds, leaks in each valve, and the condition of the silicone gel valve.

Why is cleanliness of the switchyard important during the inspection?

The cleanliness of the switchyard is important to ensure safety and proper functioning of the equipment, as dirt or debris can interfere with the operation and maintenance of the equipment.
