A current single line, an updated arc flash and coordination study, a recent power quality and harmonics study are all parts of ensuring a safe and reliable electrical system. Regular maintenance and testing per NFPA 70B and NETA MTS standards help ensure proper and effective operation, while having an engineered design and both long- and short-term planning are critical for future longevity.

Since the earth doesn’t come with a convenient electrical terminal to facilitate that connection we have to improvise. Ground electrodes can come in the form of ground rods, plates, underground water pipes, metal in-ground support structures, grids, pipe electrodes, ground rings, and similar structures as allowed by the National Electric Code.

Transformers and Oil Analysis

The insulating oil in a transformer is intended to serve two primary functions. First, as an electrical insulation to withstand the high voltages present inside the transformer. Secondly, to serve as a heat transfer medium to dissipate the heat generated within the transformer windings.

So, Is It A Switchboard Or Switchgear?
