An electrical meter shows an average monthly reading as follows kva 415 units per month kwh 120 units per month can this be correct we are paying a huge amount for the kva usage?

The meter shows the load has a very poor Power Factor of about 30%. It appears this service has a very large capacity -- most of it not used. Taking one or more (like for X-Ray or similar machine) Transformers out of service may help improve PF.
