Approved for January 13, 2026 calendar
EXECUTIVE SUMMARY
GWP needs to hire a contract to perform oil testing due to the expertise and sophisticated equipment needed, as well as the critical nature of regularly monitoring the oil for transformers, load tap changers, regulators, and circuit breakers. Additionally, due to the aging equipment, it is important to have a capable contractor that can determine the current state of the equipment and to assist in determining the appropriate plans of action to remedy any issues to increase power system reliability.
RECOMMENDATION
Adopt Specification No. 4013 to furnish materials, equipment, and labor for testing transformer, load tap changer, regulator, and circuit breaker oil, and direct the City Clerk to advertise for bids.
ANALYSIS
GWP must continually monitor the condition of its oil-immersed electrical equipment to meet this commitment. Oil testing is a standard industry practice to effectively accomplish this task. Oil testing includes taking necessary oil samples from transformers, load tap changers, regulators, and oil circuit breakers, and analyzing these samples for Dissolved Gasses; Total Combustible Gases; Moisture Content; Interfacial Tension; Acidity; Color; Specific Gravity; Dielectric Breakdown Voltage; Polychlorinated Biphenyls (PCB), and other characteristics. A high degree of specific expertise is needed to perform this type of work.
Specification No. 4013 will enable a qualified contractor to continue performing these tasks as part of GWP’s overall annual maintenance program. 24f
