 (Power System Audit) A Power Engineering and Operations Review is a detailed analysis of all of the power systems at the site including the condition and capacity of all of the DC telecommunications power systems and the capacity and condition of the AC plant and associated feeders and circuit breakers. The review then looks at the condition and capacity of the engine/alternator including a check of performed maintenance routines. In addition, a detailed review of the AC and DC grounding systems is performed. 
  • A survey of the capacity of the DC plant, to include the rectifier and battery capacities.

 

  • Determination of the configuration to ensure functionality, distribution of the plant load, AC feed, the alarm system (local and downstream) and accuracy of the DC plant meters. 

 

  • A verification of local maintenance, to include records, maintenance performed, equipment issues, and a written plann to ensure that the plant meets reliability standards.

 

  • Power cycle all rectifiers (if the plant meets N+1 reliability) and verify local alarms as well as alarms to a remote alarm maintenance center (if available).

 

  • Check all batteries and inter cell connectors for corosion or leaks.

 

  • A discharge test of the batteries - provided the power cycle test passes - lasting at least 20 minutes and verifying the turn around voltage. This test will also look at the float current on each battery string and the individual cell voltage and string current of each battery and string on a 10 minute interval.

 

  • Survey/inspection of the DC grounding system to include isolated/integrated ground, ground leads, electrode, current leakage and environmental hazards.

 

  • Survey/inspection of the AC grounding system to ensure proper bonding and grounding of the AC system and isolation of the AC neutral.

 

  • Inspection of the AC switch gear to ensure that there are proper maintenance records, adequate access per the National Electric Code, and proper grounding inside the cabinet.

 

  • Verification of the engine/alternator status including adequate capacity, confirmation of proper maintenance.

 

  • An inspection of all fuel and coolant systems for leaks. An inspection of oil and filters, fuel leads, exhaust venting, to verify proper maintenance.
  • Determine the age and condition of the engine start battery.
