Isolation: It means saparation between equipment and main
supply.When we want to maintain a particular equipment it
should be isolate with mains supply.Other wise we can not
maintain it.

Insulation: It means an isulating material is provided on
the (live) cables or equipment according to their voltage
rating to avoid short ckt b/w live parts and earth faults
b/w live part and ground. This for our safety as well as
equpment safety.if it is not provided may cause so many
electrical hazards or limit the usage of cables in various
places.

Insolation - Sudden prostration due to exposure to the sun
or excessive heat.(eg. sunstroke, thermic fever)

Isolation - setting something apart from others. Seperation.
(eg. electrical Isolator)

Answer / alok & kapil

Insolation is a measure of solar radiation energy received
on a given surface area in a given time. The name comes
from a portmanteau of the words incident solar radiation.
It is commonly expressed as average irradiance in watts per
square meter (W/m2) or kilowatt-hours per square meter per
day (kW·h/(m2·day)) (or hours/day). In the case of
photovoltaics it is commonly measured as kWh/(kWp·y)
(kilowatt hours per year per kilowatt peak rating).

isolation- isolation means to isolate or sepsrate two live
electrical parts .

Three set (each phase contain 2 cable of 400 mmsq CU XLPE AWA) of single core cables are connected to 11 KV motor of 14 MW & the switch gear supplay is taken from 11kv feeder & this supplay taken from 275 KV substation. Problem is one pair cable(L3- 2 cable ) getting very hot & gland melted and damaged in switch gear side. the other two cable haven't any more hot(ambient temp only & L3 haveing 95- 100 Degree C. The same problem happened in 275 KV substation switch gear side also where the supply taken for 11 kv switch gear. But here L2 phese cable had problem. Why it is happening like this?. The cable having temperature different at different location from gland side inthe case of 11KV feeder of 275 kv substation. why ?
