Coaxial cables are an interesting piece of the signal measurement paraphernalia . They can virtually be found on every instrumentation table in labs and yet we pretty much overlook their function. They can be simply seen as a piece of wire or as a transmission line, all ultimately depending on the frequency of the signals […]

HFCT from scratch!
In this blog, I want to share a very nice experience that came out after needing a sensor to capture a very fast and short current pulse at the HV lab. A high-frequency current transformer most likely pops up in everyone’s mind right away and certainly, there are plenty of them somewhere in the lab. […]
Acquisition of PD signals by oscilloscopes
In the last few years, I have come across with some works in which the acquisition of PD signals is done by oscilloscopes. The fact that caught my attention is that often the scope is set to record data continuously during tens of milliseconds (several cycles of power frequency). We can call this configuration “time-based […]
