Reliability Centered Maintenance Study on Voltage Regulators

This reliability centered maintenance (RCM) study was performed on voltage regulators at an electric utility by utilizing reliability analyses and predictive modeling to improve their maintenance program. The study determined reliability of voltage regulators and developed regression equations based on operating variables by analyzing the number and types of failures occurring on various classifications of voltage regulators under normal operations. The study produced practical findings and specific recommendations for creating new preventative and predictive maintenance procedures on single-phase voltage regulators.
