Hi all,
Can someone please help me understand nameplate transformer impedance values better, and how it can be used for varying loads.
I realize that the nameplate transformer impedance (let's call it Z%) is by definition the voltage (in pu) that causes full load current circulation in the...
Dear all,
We have an application where we are installing low voltage CTs on a medium voltage system.
The CTs will be installed on insulated cables on the secondary of a transformer, that is operating at 5kV.
As you are aware, it is fine to use LV CTs on MV systems as long as the system has...
Dear colleagues,
I have a few questions with regards to power quality standards.
I will first outline the application I am currently working on and the reason that I'm raising these questions (background).
Background:
I'm working on a relatively large-sized VFD application; this VFD feeds a...
Hi all,
Does anyone know what kind of PTs would be suitable to use for harmonics measurements?
Note that in our application we need to do harmonic measurements at a high voltage bus, and since our measurement device can only go up to 1000v, we need to use a PT to step down the voltage to feed...
