Answer Posted / debasis sahoo
During installation of Transformer on a Pole mounting structure, following checks should be made:
Ensure that the base channel of transformer is at height complying to IEC Standards:
a) Height of top of HV bushing from ground for pole mounted transformer should be 4.572 meters minimum (15 Ft)
b) Height of top of HV bushing from ground for plinth mounted transformer should be 2.75 meters minimum (8 Ft)
Ensure that base channel is horizontally leveled
Avoid jerky movement of the transformer while lifting it upwards during installation
During installation ensure that the HV bushings of the transformer are on the DO unit (or HG fuse unit) side of the structure
After installation of transformer, also check that other allied equipments such as AB switch, Horn Gap fuse units, DO Fuse sets, Lightening arrestor etc. are fitted at appropriate positions as per the applicable drawing issued by the utility.
Use PVC unarmoured cable (3 ½ core) of appropriate size and length for LV side. Ensure that the lugs are appropriately crimped at the ends.
