As the battery is discharged, or used, the acid concentration decreases and becomes weaker (dilute) until the battery cannot produce an electrical current. This makes it possible to tell the state of charge by seeing how weak the electrolyte is. A hydrometer is used to measure the strength of the electrolyte. Both negative and
Before designing or installing a battery system, the electrical designer or electrician should be very familiar with all of the hazards involved, as well as the minimum safety requirements of the NEC.
This section provides additional requirements for substations and for work performed in them. 1926.966 (b) Access and working space. The employer shall provide and maintain sufficient …
Battery discharge testing seems to be a controversial subject among battery users. It is admittedly the most expensive part of a battery maintenance program both in terms of labor and equipment costs. Yet it remains a fixture in the Institute of Electrical and Electronics Engineers Inc. (IEEE1) battery maintenance standards. The recent article ...

4. Precautions for outdoor installation of substation cabinets. The grounding conductor of the substation cabinet must be a copper conductor, and the cross-section must not be less than 30mm2. For some equipment that deliberately reduces the specifications of the grounding conductor, it is easy to be damaged by lightning strikes.
NERC standards make battery maintenance mandatory and its requirements are more stringent than those for other equipment. Very specific activities and maintenances schedules are described in PRC-005. Failing to comply with these requirements can reduce the life and performance of batteries, in addition to incurring fines.
