Substation Maintenance Best Practices

Improving substation maintenance best practices for greater success

BY BUDO MILOVIC, DV-Power

Currently, substation maintenance—regular or emergency—operations and best practices must fit the utility’s goal of accomplishing more with less, in order to maximize assets and minimize outages. A caveat to this weighty goal is to accomplish more with less with a reduced workforce and under tight budgets. Field workers face this reality daily. Therefore, to overcome such challenges, maintenance crews have to be properly...
