Tech/Engineering - Electronics / Elect Eng / Disturbance recorders; Transformers
Swedish term or phrase: andratonsblockering
Hello, and SOS:

I need help with a highly technical project.

The topic is störningsskrivare / disturbance recorders.

I have several words I need help with, so I will do a few posts to cover them all individually.

The fifth word is: andratonsblockering

Please find a sample sentence for context:
Andratonsblockeringar av jordströmsskydd.


Thank you so much in advance.

Explanation:
"second harmonic blocking method to provide security during energization"
https://pcmp.springeropen.com/articles/10.1186/s41601-019-01...

"The presence of second harmonics in the magnetizing inrush current can be used to identify transformer inrush currents."
https://cdn.selinc.com/assets/Literature/Publications/Applic...

"The rich second harmonic component in inrush current is most commonly used to identify the condition of transformer energization... With harmonic blocking, usually the second harmonic component is used (fourth harmonic is used by some relay manufacturers)."

"en av parametrarna som kontrolleras för att erhålla en tillfredställande elkvalitet är övertoner."
"one of the parameters that have to be controlled to get an acceptable power quality is harmonics."
