Lightning Arrester is a device used on Elctrical Power
Systems. It is used to protect the insulation of the
system.When a lighting surge travels along the power line
to the arrester, the current from the surge is diverted
through the arrestor in most cases to earth.
Wave Trap is a device used on Electrical power sysems. It
can descriminate the Power Frequency waves and power
communication waves and it reduce the noise and
interference from line.

HELLO EVERYONE, I RECENTLY HAVE FOUND ONE PROBLEM, I WAS TAKING NO LOAD TRIAL OF AN HT MOTOR 920 MOTOR , 1440 RPM , 6.6 KV, WITH AUTO TRANSFORMER. AT 450 V, LOAD WAS 40 AMP AND SPEED WAS 250 RPM. BUT AS WE INCREASE VOLTAGE FROM 450 TO 480V, LOAD BECOME 41 AND SPEED REDUCED TO SOME RPM . SO WHICH PHENOMENON ACTED HERE FOR REDUCING SPEED.?? AND IS IT HAPPENING ALWAYS OR IT IS RARE? I ALSO HAVE FACED SUCH PROBLEM WITH FEW LT MOTOR ALSO.
