How to maintain the pole-mounted power transformer?

Here are the key steps for maintaining pole - mounted transformers:

Regular Checks

Look at the pole transformer's shell for damage or oil leaks. Fix leaks quickly. Check the bushings for dirt, cracks, or damage. Clean or replace them if needed.

Check the grounding wires for rust or breaks. Tighten loose bolts to keep the ground safe.

Watch the oil level. Add oil if it's low. Also, check the temperature. If it's too high, find out why and fix it.

Sound and Smell

Listen to the pole distribution transformer. A strange sound means trouble. If you smell something burning, turn it off and check it.

Resistance Test

Test the insulation resistance regularly. Low resistance shows problems with insulation. Fix it right away.

Tap Changer

Make sure the tap changer is in the right place and working well. Check for overheating.

Protection

Before bad weather, check lightning protection devices. Also, check the grounding system. Repair any damaged parts.

Surroundings

Keep the area around the 3 phase pole transformer clean. Remove debris and branches. Check the protective fence for damage.

Always have professionals do the maintenance. This helps the pole transformer work safely and well.
