California state utility regulations require a minimum of 3 inspections per year.

For Liberty Utilities there was nothing convenient in place to track these inspections. In addition, a lot of substation expertise had retired or left the company and there was no substation inspection program in place.

Liberty Utilities had just hired a new substation technician and was looking for a consistent substation inspection program.

The engineer tasked with the inspection program told the inspector to walk through the substations and look for problems.

Protection Zone Management provided Liberty Utilities with a comprehensive inspection program that not only provided detailed inspection questions for each piece of equipment, but also scheduled each equipment inspection on a cycle that met the State regulation.

PZM provided a scheduled and standardized inspection program that was needed due to the retirements and attrition that so often happens in smaller operations.

"PZM has been a great addition to our substation inspection program. It is especially nice to have the inspection cycles set-up in the program and take away the need to have to schedule the inspections manually and risk not meeting the State regulations." – Calvin Humphrey, Liberty Utility Substation Foreman.

Liberty Utilities continues to use PZM to document and schedule comprehensive substation inspections.

PZM has been a great addition to our substation inspection program.
