4. Automatic Transfer Switches (ATS) Service Provider shall perform preventative maintenance of ATS, including inspection and cleaning of contacts, lubrication of mechanical components, torque verification of electrical connections, and operational testing of manual transfer sequences under load. All work shall conform to NETA MTS and manufacturer specifications. Service Provider shall provide service report documenting findings, as found/left settings, and recommendations for any deficiencies detected.

5. High and Low Voltage Panels Panel Preventative Maintenance shall encompass a visual inspection for heat damage, corrosion, and loose connections.

Thermal scanning shall be performed to determine if any hotspots are present. Torque verification, breaker exercising, and trip testing shall be performed. Insulation resistance testing as well as interior cleaning shall also be performed.

Documentation of all results and finding shall be included in the service report.

6. Electrical Transformers Scheduled transformer PMs ensure reliable commercial power distribution, prevents cascading electrical faults, and allows the realization of equipment life spans. The program is intended to identify thermal degradation, mechanical wear, and insulation breakdown. This should minimize catastrophic failures and ensure continuous operation.

E. PM Checklists The Preventive Maintenance checks listed are a minimum list of required tasks that Gwinnett County demands to be performed. It is expected that Service Providers will add additional tasks, as necessary. This will ensure our equipment has minimal downtime and maximum service life, as well as keeping warranties, when present, intact.

At the beginning of each month the County’s Computer Maintenance Management software automatically generates the PMs for the given month, these will be sent to the Service Provider(s). All PMs must be performed in the stated month.

Departments may have slightly different processes. Failure to perform PM in assigned month may result in forfeiture of that PM. PM checklists can be found in section below.

F. Priority Matrix

PRIORITY DESCRIPTION REQUIRED ACTION

Critical Immediate safety or operational risk Notify DDR immediately; repair prior to returning equipment to service

Serious Potential Failure condition Repair within next scheduled outage

Moderate Degraded condition Monitor and schedule repair Minor Low-Risk or cosmetic condition Correct during next PM cycle
