What are the causes of low power factor?
by

1 Answer

Answer :

The following are the causes of low power factor  otors are of induction type which have low lagging power factor.  These motors work at a power factor which is extremely small on light load 0.2 to 0.3 and rises to 0.8 to 0.9 at full load.   heating furnaces operate at low  lagging power factor.   during morning and evening and  low at other times. During low load period, supply voltage is increased which increases  the magnetization current. This results in the decreased power factor. 14) Define the term connected load factor.  It is the sum of the continuous rating in KW of all electrical devices installed at the  consumer’s premises and connected to the supply system.
