Answer / Rohit Kumar Singh

The selection of a lightning arrester requires considering several parameters such as voltage level, insulation level, short-circuit current, peak surge current, and impulse voltage. Other factors include environmental conditions, installation height, and the type of protection required (direct or indirect). Additionally, compliance with relevant standards like IEC 60335, IEC 60090, and IEEE Std 1100 should be ensured.

I need to compare the energy consumption of an industrial machine before and after improving. Shall I compare the apparent power or the active power? I know usually factories use compensated capacitors (or other similar components) to compensate the reactive power, so if I use the apparent power, it's not the real power consumed.
