what is power factor for any engineering equipment?? what
should be its value?

Answer Posted / raji g

We can simply say that the power factor is how the machine
effectively consume the active power.For example if the
motor runs at 0.8pf it consumes 80% of active power and 20%
of reactive power.

Theoretically speaking the power factor is defined as the
cosine value of angle which between the voltage and current

what is the voltage rating of chiller unit sensors

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.
