What is the difference between PT for metering and PT for protection ?
Answer Posted / maqbul
Metering PT used for measuring purpose and it is design to operate on knee point of flux v/s I curve..
Metering PT has less volume of core...
While protecting PT is used for protection purpose and it is design to operate on ankle point of flux v/s I curve.
Protecting PT has more volume of core..

L.A. (Lightening Arrester) is located at a place from where transmission line enters the transmitting substation. So L.A. (Lightening Arrester) is the first equipments which has to encounter with lightening, high voltage surges and switching surges. It has to absorb energy of lightening, high voltage surges, and switching surges. L.A. (Lightening Arrester) is made up of layers of semiconductors. If these layers can not tolerate energy released by lightening, high voltage surges, and switching surges the L.A. (Lightening Arrester) blasts.
