Generator Step-Up (GSU)

Generator step up is done by transformers directly connected to the generator output terminals. This is usually done via busbars in large generating stations. They normally have a high voltage in secondary and high current in primary.

Gassing (Battery)

The evolution of gas from one or more of the electrodes in a cell. Gassing commonly results from local action (self discharge) or from the electrolysis of water in the electrolyte during charging.

Fused Cutout

A device, normally installed overhead, that is used to fuse a line or electrical apparatus.

Fuse Melt Time
