I coincide with the opinion that the thumb rule of KV+1 for
is not suitable for cables . For cables there shall be a
minimum value which shall be more than the value derived as
per the kv+1.The IR value varies with the operating
temperature. The value shall be high at at ambient
temperature and low at higher temperatures. However megaar
instrument 1 kv upto 1 kv rating and 2.5 kv to 5 kv upto
and including 33 kv
