UHF PD Detector-Handheld Online PD Substation surveying system

Component failure in a substation has serious repercussions. It has the potential to cause injury, damage and unplanned outages, which result in significant disruption and cost. Predictive condition assessment aims to identify faults developing in electrical equipment so that they can be addressed before failure.Adiradh Energy offering UHF PD Detector is the ideal tool for quick, non-invasive surveys in MV and HV substations and should be part of the toolkit for all maintenance and service teams. Due to its high measurement bandwidth, the UHF method provides accurate local online partial discharge (PD) measurements on HV components such as cable end-terminations, surge arrestors, voltage transformers and isolators.Dual measurement channels allow two phases or two types of UHF sensors to be compared, which further increases the scope of use of the UHF Detector. MV switchgear surveys can also be carried out using the radio frequencies in combination with the wide selection of TEV and HFCT sensors.

PD substation surveying device

Handheld online PD substation surveying device-UHF partial discharge (PD) detector

The phase resolved PD pattern (PRPD) display helps to identify type of defect and, importantly, differentiate the noise from the PD signal. Noise can affect PD readings, leading to a false interpretation of the results and unnecessary component replacement. The noise handling capability of the Megger UFH PDD ensures a true reading of PD, eliminating false positives, so only failing component are identified for replacement.The handheld unit can either be operated using a keypad or using the large 6” colour touch-screen. It has a battery life of over 10 hours. Its mix of features and performance make the UHF detector the most  cost effective unit of its kind.

Overview of UHF PD Detector 

■  Non-invasive tool for online PD measurements in MV and HV substations
■  Large colour touch-screen for easy operation
■  Dual channel system for direct comparison between two sensors
■  Synchronises with power frequency via internal, mains or external sensor for PRPD pattern recognition

The standard UHF PD Detector comes with a di-pole antenna for UHF surveying. Inductive (HFCT) and capacitive (TEV) sen-sors for measuring MV cables and switchgears are available as optional extras. A UHF PD coupling sensor is also availa-ble, offering the most detailed and precise measurements for HV components like terminations. The sensor is applicable up to 400kV rated systems
