Hello everyone,
During relay testing, we apply voltage to the secondary of the capacitive voltage transformer (CVT). Some colleagues disconnect the secondary terminals going to the field, believing that high voltage may appear on the primary side during the test. However, I think this is...
Hello everyone .
We have used relay test kits from brands like Kingsine, Omicron CMC356, Sverker, and Freja. Among them, Omicron was the most user-friendly. However, the Kingsine relay test kit also caught our attention as its computer interface seems quite practical.
According to the...
Hello everyone, I wonder if 2 90 degree cross measurements (traverses) are sufficient in the wind turbine field? According to BN 50522, spans (a = 1 m - 1.5 m - 2m - 3m - 4.5m - 6m - 9m - 13.5m) are recommended as amax = 13.5 m. Does anyone have a different comment or advice on this subject?

Hi all.
How many measurements do I need for soil resistivity? Some say 2 measurements are enough, while others say 5 measurements are needed (1 for each edge and cross section). What do you suggest? I've even seen 10 measurements. As you know, I'll take the average of these measurements. I want...
