To be competitive, some electrical contractors often supply low-voltage (LV) service entrance switchboards and switchgear that meet the minimum safety requirements of the National Electrical Code (NEC ...

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, allowing engineers to test protective relays under controlled conditions.

Medium-voltage motors are critical to a facility’s power system. Not only are they expensive, but their failure can have crippling, long-lasting impacts on a plant’s operation. As such, properly ...

Electrostatic discharge (ESD) protection is critical at advanced nodes to safeguard designs against effects intensified by shrinking transistor dimensions and oxide layer thicknesses. On the other ...

As the electric distribution system transforms into a smarter network, Commonwealth Edison Co.’s distribution automation team has embarked on a step-change journey that will transform distribution ...
