What is C.T, why it is used and what care should be taken
for that while connecting?
Answer Posted / iamsazz
It is current transformer. It mainly gives low amper in O/P
with respect to I/P. Output is in proportional to Input. By
this can measure high current flowing in line (say 10,000
A) using CT. The secondary should always be shorted for
protection before connecting to circuit unless it will
burst and caught fire.

A commercial Building is designed with 14th floor levels with indoor substation of three phase transformer with rated capacity of 1000 Kva.The transformer delivered 65% of its rated capacity at 0.67 power factor lagging.Because of low power factor, the power customer was penalized and certain cost was charged accordingly based on every point percentage lower than 85%.This situation may repeatedly happen on the succeding energy bills of power customer.The power customer is desired to improve its historical power factor of 0.67 lagging and no further penalty be impose by the local power company on the next bill.
