Energy Audit for St Mary Redcliffe Church, Bristol

3.2. Mains Supply
The Church has an incoming three phase mains electrical supply
and a supply voltage of 237v. (Note the second meter appears to
be for the phone mast). This voltage is higher than required and
could explain some of the reason for the higher incidents of
lighting replacement. The voltage can be reduced to around
220V quite safely and without affecting the performance of any
of the electrical equipment. Reducing the voltage will not only
produce an energy saving but will also help to protect any
lighting and sound equipment from problems associated with
high voltage which can shorten their life. A simple 100A 3 phase
unit can be obtained from SavaWatt controls (Campbell Hodgetts

3.3. Small Power
During the site visit it was noted that there are other small electrical usages, the most significant of
which is likely to be the organ blower however this does have inverter drives on the motors and
therefore no further recommendations are made in this regard.
