SF6 gas test selection scheme

SF6 Gas Relay Inspection

Cycle	Requirements
1) After major maintenance 2) When required	1) Follow the manufacturer's technical guidelines 2) The set value must meet the operational standards and the response should be accurate.

SF6 Moisture (Dew Point) Test

Cycle	Requirements
1) After major maintenance 2) When needed	Follow the manufacturer’s technical specifications

SF6 Gas Leak Test

Cycle	Requirements
1) After major maintenance 2) When necessary	Annual leakage rate ≤1% or as per the manufacturer's instructions

AC Voltage Withstand Test for Capacitive Voltage Divider of Coupling Capacitor and Capacitive Voltage Transformer

Cycle	Requirements
When necessary	The test voltage should be 75% of the factory test level

This detailed testing procedure ensures the safe and efficient operation of electrical equipment using SF6 gas. Regular inspections and tests are crucial to detect any faults or leaks early and prevent potential failures. It is recommended to follow the manufacturer's guidelines strictly and maintain proper documentation for all test results.

Fuse Cutout

The primary purpose of any fuse cutouts is to provide protection to the lines of your system and the various apparatus on those lines such as transformers and capacitor banks. Fuse cutouts provide reliable protection from low-level overloads that just melt the fuse link, intermediate faults, and very high faults, through maximum interrupting capacity.
