A transformer protection relay does not replace upstream devices. It defines responsibility. By clearly assigning fault ...

What distinguishes a medium voltage circuit breaker from other types is not the enclosure or operating mechanism, but the method of arc extinction. The interruption medium governs arc energy, ...

Puzzled by choosing circuit protection devices? Follow these guidelines and your electrical system will fall into place. Is it sufficient to select protective devices based entirely on their ability ...

One of the most dangerous locations in a power distribution system with regard to incident energy is that first panelboard on the secondary of a transformer. With some thought in your design — even if ...

Circuit breakers such as E-T-A's model 2210-S can offer high-current protection using different interrupting capacities. Interrupting a short circuit�current flow limited only by the resistance of ...

Circuit breakers now sport advanced features that include remote control and operational status reporting. Engineers have long considered circuit protection a stable if somewhat unglamorous area.

My introduction to circuit protection came at the tender age of eight. Being a curious lad with an inventive – and apparently self-destructive – bent, I decided to make my mother a lamp. I put a hose ...

TO BE READ BY ALL ELECTROSCHEMATICS ENTHUSIASTS! Much needs to be said about this oft neglected subject. We would never even think of connecting the utility mains to our house without proper circuit ...
