Yesterday I surveyed the three phase line supplying three 500 kva transformer.
I'm starting from the tapping pole until last. The reason is to find out what is the main
cause of the tripping in as I noticed in every curve road the construction of the
poles at the top button where the pin insulator installed very near to the steel crossarm
resulting single or double line fault occur specially in rainy season.
therefore we come up a solution to install bogshoe after the angle pin and insulator
to have an extension distance between the primary line wire to steel crossarm.
