Spectroscopic Investigation of Metal Content in Prestrike Arc During Making Operation in a Low-Current Model Switch [PDF]
, 2020 Energy dissipation during prestrike arc is the critical factor for electrical contacts erosion and welding in medium voltage load break switches. Using air-filled devices as an alternative to SF₆ makes the switch environmentally friendly, but leads to a ...

An Experimental Study of Short-Circuit Current Making Operation of Air Medium-Voltage Load Break Switches [PDF]
, 2022 Replacing SF 6 , the most potent greenhouse gas, with an alternative gas is a challenge faced by medium-voltage load break switches (MV-LBS). Air is a possible alternative, but there are some challenges regarding low dielectric strength leading to high ...

A critical review on soil ionisation modelling for grounding electrodes [PDF]
, 2016 Grounding electrode resistance non-linearly changes under impulse conditions due to soil ionisation phenomenon. Several models have been proposed to model soil ionisation for grounding electrodes applications.

Morlet Wavelet UDWT Denoising and EMD based Bearing Fault Diagnosis [PDF]
Electronics, 2013 Bearing Faults in rotating machinery occur as low energy impulses in their vibration signal and are lost in the noise. This signal has to be properly denoised before analyzing for effective condition monitoring.
