Impedance-based fault location is widely used throughout the power transmission and distribution industry. In fact, for most numerical relays, one-ended…
The main objective of any protection system is to interrupt short-circuits as fast as possible. The means to achieve this…
Abstract: There are a lot of methods that can be used for short-circuit current calculation. One method was previously discussed here…
The selection of the short-circuit rating of power fuses and low voltage circuit breakers are treated differently than medium and…
Electrical reclosers are widely used in overhead electrical distribution systems to detect and interrupt momentary faults mostly due to vegetation,…
Short circuit analysis using ETAP software based on IEC 60909 standard. In the previous discussion, we have presented the step-by-step…
Circuit breaker short-circuit duty calculation is a very important step in our discussion on IEC 60909. We had just completed…
Short circuit calculation using ETAP can be done through the 'Short Circuit Analysis' module. This module allows the calculation of…
Circuit breaker sizing calculation for medium- and high-voltage circuit breakers basically involves two symmetrical current calculations, one for the first…
In this article, we will present a discussion on transformer differential protection calculation through an application example. So far we…
