Reliability Assured

NERC Standard PRC-005 was created to assess the reliability of batteries used in the utility industry. NERC works to educate, train, and certify industry personnel for system awareness. This includes 4-, 6-, and 18-month maintenance requirements to be performed on VLA, VRLA, and NiCad batteries to remain compliant.

STANDARD PRC-005-2 PROTECTION SYSTEM MAINTENANCE

VENTED LEAD-ACID ( VLA ) BATTERIES

 

Maintenance Activities:

4 CALENDAR MONTHS

  • Verify station dc supply voltage
  • Inspect electrolyte level
  • Inspect for unintentional grounds

 

18 CALENDAR MONTHS

  • Verify float voltage of battery charger
  • Verify battery continuity
  • Verify battery terminal connection resistance
  • Verify battery intercell or unit-to-unit connection resistance
  • Inspect cell condition of all individual battery cells where cells are visible – or measure battery cell/unit internal ohmic values where the cells are not visible
  • Inspect physical condition of battery rack

 

18 CALENDAR MONTHS

Verify that the battery can perform as manufactured by evaluating cell/unit measurements indicative of battery performance (e.g. internal ohmic values or float current) against the battery baseline

OR

6 CALENDAR YEARS

Verify that the battery can perform as manufactured by conducting a performance or modified performance capacity test of the entire battery bank
