Note: All Code references are based on the 2014 NEC. The NEC has separate sections for transformer feeder protection and transformer protection. Article 240 lists requirements for transformer feeder ...

The latest version of RelaySimTest (V3.20) enables users to extend the benefits of system-based testing to transformer protection 1. Instead of adopting the usual approach of simply testing the ...

The addition of flexural stiffeners on the transformer cover plates was explored as a means to stiffen the base of the bushings and mitigate their seismic vulnerability. Numerical and experimental ...

Omicron's CT Analyzer provides fast and cost-effective testing and verification of current transformers for protection and metering applications. It automatically determines all relevant current ...

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 ...

Most switching power-supply controllers provide non-latching fault protection. Satisfying a requirement for a latchoff response to a fault often requires the addition of excessive and redundant ...
