The art of protecting electrical systems, part 18: protecting wires and cables

Part 18 of our continuing series on protecting electrical systems begins a series of articles on protection of electrical systems components, starting with conductors.

The Art of Protecting Electrical Systems, Part 17: Computer Software and Electrical Design

Part 16 of this continuing series looked at computer programs used to assist in electrical system design and protection. Part 17 continues a look at how one computer program assists engineers in electrical system design.

The art of protecting electrical systems, part 16—software speeds electrical design

Part 16 in this continuing series looks at computer programs used to assist in electrical system design and protection.

The art of protecting electrical systems, part 13: calculating short-circuit current at secondary of transformers

In this 13th installment of an ongoing series, the authors present calculations for available fault currents at the secondaries of three-phase transformers having secondary voltages of 120/208 to 600 V.
