Operations of maintenance in distribution transformers:

Tightening transformer terminals.
Check the transformer's isolations.
Checking protective instruments and proper function (testing) system protection (Buccholz - Thermometer).
Tightening the terminal and shell transformers.

Measurement of earthing.
Check and test the system of ventilation of the area.
Check terminal box.
Check and change the dehumidifier (silica gel) instrument.
