IEC 61557 requirements for test equipment provide the user with safer installation testers

The tougher IEC 61557 requirements for test equipment provide the user with safer, more reliable and easier to use installation testers that deliver results in accordance with IEC 60364 (and its national equivalents). The change has been officially in force from 1st January 2007. Installation testers verify the safety of electrical installations in domestic, commercial and industrial applications. They are used to carry out tests to ensure th... [more]

Who tests the testers?

Proper testing of electrical installations in buildings is essential to ensure their safety. However, if the tests are performed with inaccurate instruments, the result is, in some ways, worse than no testing at all – incorrect measurements may create a false sense of security by indicating that all is well when, in fact, there are serious deficiencies. Because of this, electrical contractors are required to regularly check the accuracy of the... [more]

New AC Leakage Current Clamp Meter for non-invasive insulation resistance checks

Leakage currents can be an indicator of the effectiveness of insulation on conductors. High levels of leakage current may be present in circuits where either the insulation resistance is low, or electronic equipment with filters is used. Leakage currents can cause disruptions to the normal operation of equipment and installations. Fluke has introduced the Fluke 360 AC Leakage Clamp Meter, a rugged, lightweight, pocket-sized current clamp desi... [more]

Megger offers new test lead options for safety and convenience
