in most industies hormonics present up to some level. what
is limit ? and there effect?
Answer Posted / ashim kumar das
In an industry harmonics are measured as TOTAL HARMONIC
DISTORITION (THD), which permissible limit in most of the
industries is 3%.
No doubt harmonic create losses, moreover puncture of
Capacitor banks,unwanted heating of motor are also the main
disadvantages of harmonics.

A 400 V, 50 Hz, Δ connected synchronous generator has a field reactance of 0.1 Ω and armature resistance of 0.015 Ω. At full load, the machine supplies 1200 A at 0.8 pf lagging. Under full-load conditions, the friction and windage losses are 40 KW and the core losses are 30 KW. What is the machine’s overall efficiency? Ignore any field circuit losses.
