Guidance for the installation and installation design of valve-regulated lead-acid (VRLA) batteries is provided in this recommended practice. This recommended practice is intended for all standby stationary installations. However, specific…
Vented lead-acid (VLA), valve-regulated lead-acid (VRLA), nickel-cadmium (Ni-Cd - both fully vented and partially-recombinant types), and Li-ion stationary battery installations are discussed in this guide, written to serve as a…
The neutral grounding of single- and three-phase ac electric-utility primary distribution systems with nominal voltages in the range of 2.4 kV – 34.5 kV is addressed. Classes of distribution-systems grounding…
Electric power system reliability remains an important societal issue. Transmission disturbances draw national attention and scrutiny, but service interruptions at the distribution level are the primary concern of end-use customers…
This recommended practice is intended to serve in the preparation of standards that are principally concerned with the thermal endurance of electrical insulating materials and simple combinations of such materials,…
Direction and methods for qualifying permanent connections used for substation grounding are provided in this standard. This standard particularly addresses the connection used within the grid system, the connection used…
This standard defines and describes the technical requirements, tests, inspection rules, marking, package, transportation, and storage of wedge-shaped groove clamps, which are used in connections and branches of aerial conductors…
This guide applies to silicone-immersed transformers in which the silicone fluid was the fluid supplied when the transformer was originally manufactured. This guide also addresses the following: a) The theory…
Specifications that should be provided to characterize instrumentation used to measure the steady state root mean square (rms) value of magnetic and electric fields with sinusoidal frequency content in the…
