UHF PD Diagnosis at high voltage cable terminations
High voltage terminations are essential components in high voltage cable systems. Great reliability is provided by high manufacturing quality and company type testing. However, onsite installations represent a considerable uncertainty for successful service of the system. UHF PD Diagnosis has proven to be a valuable and effective method for measuring high voltage assets because this online measurement is performed at frequencies which are not affected by environmental noise.

Testing wind turbine lightning protection
The most significant danger facing wind turbines is damage from lightning strikes. Lightning faults cause more loss in wind turbine availability and production than the average fault. The number of failures due to lightning strikes is known to increase with tower height and a growing number of studies speculate that rotating wind turbines may be more susceptible to lightning strikes than stationary structures.

The “ART” of earth electrode testing - Megger DET3TC with ICLAMP option
The testing of earth systems has relied for many years on the tried and tested “Fall of Potential” and other related methods. These methods give reliable results, but can be time consuming. This paper looks at Megger's Attached Rod Technique as a new solution to the issue of earth testing.

The batteries that radar UPS systems depend on need regular testing to ensure that the skies stay safe
Batteries play a crucial role in ensuring that air traffic control systems around the world can continue to operate reliably and safely, even if there is a failure of the mains supply at the radar stations on which they rely. It is imperative, therefore, that those batteries should be maintained in good condition, with potential problems detected and remedied before they can develop into outright failures.
