About the Safety and Maintenance Points of 75 kVA Pole Mounted Transformer

Regular inspection is required during the use of the transformer:

  1. Inspect the oil level and bushing condition every week, and deal with oil leakage points in time.
  2. Test the grounding resistance every quarter, and strengthen inspection before the rainy season.
  3. Conduct oil sample testing every year. If the breakdown voltage is lower than 30 kV, the oil must be replaced.
  4. If abnormal humming is heard, cut off power immediately for inspection. It may be caused by internal looseness.

FAQ

What is the difference between single-phase and three-phase Pole Mounted Transformer?

Single-phase is suitable for small loads such as households; three-phase handles heavy-load industrial/commercial facilities.

Can Pole Mounted Transformer be used in rural areas?

Yes, and it is very suitable for rural electrification projects with limited ground space.

How often should Pole Mounted Transformer be maintained?

Oil inspection, insulation testing, and structural inspection should be carried out at least once a year or according to local regulations.

What is the service life of Pole Mounted Transformer?

If properly maintained, most units can be used for 25–40 years, depending on environmental conditions and load cycle.

What is the difference between Pole Mounted Transformer and ground-mounted transformer?

Pole-mounted transformers are suspended on utility poles and used in overhead power systems; while pad-mounted transformers are installed on the ground, enclosed, and more suitable for underground power systems.
