Answer / joy
"Molded Case Circuit Breaker" (MCCB) is a circuit breaker
and trip device assembled in a mould case. The case
functions as both an outer wrapper and to retain in proper
position the breaker’s internal components. Theses cases are
made from various types of electrical insulating and fire
retardant plastic. MCCB can automatically cut off electric
power in case of overload and short circuit. It is meant for
higher rated current and is commonly used in Industrial
applications.

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. Q: Identify the appropriate solution you want to offer to Client?.Justify SCIENTIFICALLY and MATHEMATICALLY the principles behind the solution.
