Not long ago, the need to measure earth resistivity or the resistance of an earth electrode was for most engineers, a rare occurrence. With the advent of small generating schemes and in particular, ...

The Seaward Group has introduced the ERT-S electrical safety checker from its Seaward Electronic, Ltd. division. Designed specifically for earth resistance measurements, the ERT-S is a ...

The Fluke 1621 is an easy-to-use earth ground tester. For ground resistance testing, the 1621 is the first line of defense in detecting reliable ground connections. The unit features basic ground ...

Lightning protection is a critical aspect of establishments that operate sensitive electrical equipment, especially in the broadcast industry. Tied to this first line of protection against lightning ...

In the first part of this series on the highs and lows of resistance measurements, I discussed the basic principles for making two- and 4-wire resistance measurements for measuring resistances of less ...

WHEN the electrometer triode valve is used for the measurement of ionisation currents obtained in the ionisation spectrometer 1,2, a high resistance, consisting of a pencil line on amber, is commonly ...

Interpreting a data sheet for a static-control product requires a certain level of knowledge and experience. Often, you must wade through myriad specifications, test methods, and claims without fully ...
