The 500kva 33 0.415 kv distribution transformer Annual Maintenance Procedures:

For the annual inspection, component maintenance and cleaning are the key focus:

1.Use soft cotton to clean the 500kva 33 0.415 kv distribution transformer bushings.

2.Annual inspection of OLTC (On-Load Tap Changer) is crucial. Ensure moisture levels and dielectric properties are at the appropriate levels for efficient operation. (Observe oil condition and sample moisture content (PPM) and dielectric strength (BDV). Low BDV and high PPM levels indicate the need for oil replacement.)

3.Tighten all connections of control and relay circuits at least once a year. Additionally, check if the indicator heaters are at standard spacing and performing as required. Clean the marshalling box at least once a year. (The marshalling box should be cleaned. Indicator heaters should also be checked in conjunction with the space functions.)

4.Clean control switches, alarm devices, and relays along with their circuits using the specified cleaning agents.

5.Check the operation of your news release equipment.

6.Check the oil levels on indicators and ensure they contain the required oil volume for operation.

7.Measure the resistance rating of ground connections and risers. Do this by measuring ground resistance with a ground resistance tester.
