Electric power transmission and distribution systems are vital for modern life. And, since the electricity these systems provide is essential, then these systems are essential too. One of the less celebrated components of these systems is the humble surge arrester. These arresters serve the important job of keeping the electric supply smooth and steady. As such, these devices must be tested regularly as part of a maintenance program.This application note looks at what a surge arrestor is, the test procedures of insulation resistance testers, as well as present test results and recommendations.

This application note informs about testing of reclosers with ODEN/INGVAR (herafter only ODEN is mentioned, though the text is valid for both products).

This application note is about primary injection testing low voltage (LV) circuit breakers (CB) using the High Current Probe HCP2000 probe (AA-90165). Current source can be the primary test equipment ODEN or INGVAR

This application note is about primary injection testing of low voltage (LV) circuit breakers (CB) with the primary test equipment ODEN or INGVAR (hereafter only ODEN is mentioned, though the text is valid for both products), and the challenges that could arise for various CB installations.

The ground grid is intended to carry current into the earth to both protect equipment and assure personnel in the vicinity aren’t exposed to electric shock, as would result from excessive step or touch potentials.
