DEVELOPING AND IMPLEMENTING AN EFFECTIVE ELECTRICAL MAINTENANCE PROGRAM Part I: Selection Of A Testing Firm Part II: Developing Specifications Part III: Anatomy Of a Shutdown; Implementing The Program |
Planning Meeting Upon
arrival to the site for the meeting we discovered that there were two
electrical contractors working at the facility and both would be involved
with the preventative maintenance. The facilities maintenance supervisor
wanted detailed specifications on what type of testing and maintenance would
be done. They wanted this specification to be done in accordance with the
manufacturers recommended procedures. They were given a brief overview of the
typical maintenance procedures and told that a walk through of the facility
would be required to determine what equipment was installed and the general
condition. The
facility had four substations, one high voltage switch lineup and one outdoor
high voltage switch which serves as the main. Each substation was a
combination of high voltage switches, dry and liquid filled transformers,
bolted pressure switches, electronic trip and molded case circuit breakers.
The four substations were installed throughout the large manufacturing and
warehouse facility, with the main switch and one of the substations located outdoors.
Because
there were two electrical contractors involved, the substations were split
between the two. Each contractor would get two substations with one doing
additional installation work and the other responsible for the electrical
shutdown and high voltage switch maintenance. Our responsibility would be for
all distribution transformers and low voltage switchboards in the four
substations. Everyone involved would be providing labor, the facility
maintenance personnel, electrical contractor(s) and Powertronic, Inc. The
facility viewed the maintenance shutdown as an opportunity to get their
personnel familiar with the inside of the equipment and save money on project
cost. This would truly be a team effort, each entity providing their
expertise. We
were given a week to provide detailed specifications and price working
towards a Thanksgiving weekend shutdown. After reviewing this information
another meeting would be planned to outline the actual shutdown requirements.
