Insulation resistance testers above 2.5 kV
Electrical insulation degrades over a period of time because of various stresses which are imposed upon it during its normal working life. The insulation has been designed to withstand these stresses for a period of years, which would be regarded as the working life of that insulation. This often runs into decades.

Case study: True dynamic resistance measurement
Pinpointing concealed problems inside a resistive-type OLTC before physical inspection - the application of true DRM.A maintenance team at the Electric Power Transmission Network in the City of Karbala performed routine electrical tests on a transformer including: winding resistance measurements (WRM), transformer turns ratio (TTR), short circuit impedance (SCI), excitation current, and line-frequency power factor (a.k.a. dissipation factor or tan delta). This case study looks into their investigations and their results.

Less is more for electrical test instruments
A 21st century trend in electrical instrumentation has leaned toward smaller, lighter and easier to manipulate testers through microcircuitry. Being portable and easy to manipulate can be beneficial enough, but there’s much more to it. Size reduction is not just for ease of manufacturing or an advertising gimmick. Multiple instruments can be combined into a single handheld tester, so that an entire job can be completed with a single piece of test equipment. The user can benefit from notable cost savings and job improvement. This article will examine how many of the functions found in multiple different instruments can be included in just one handheld tester.
