VFD is adjustable speed drives.if u vary the pot value,it
can change frequency from 0 to 50 hz,limit amp value.as you
wish.you give information put on VFD,whether its rotate
clockwise and anticlockwise rotation of motor.speed =120f/p.
VFD----convert-ac to dc then dc to ac. then connect motor.
SS-----it has thyristor, connect with motor.its reduced
starting current.but its soft start &soft stop.

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.
