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.

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.
