Hello ZapSib, My Country is listed in Schneider Electric support contact. Furthermore, Schneider Electric Bulgaria already know about this problem. Unfortunately they refused me a support. Next time I'll think about whether to use the Сцхнеидер relay protections.

Dear All, I have problem with Signals Time Stamp sent from MiCOM Px3x to Local SCADA under IEC61850. So, we have Redundant (Ring) network with Schneider Electric relay protections - MiCOM P132, MiCOM P632, MiCOM P132, MiCOM P139, MiCOM P445 connected to two RUGGEDCOM RSG2100 switches. The...

First you have to create a new element with specific name in the NEPLAN Libraries of type “Frequency dependence”. There you adjust the parameters of the element as a function of the frequency. After that, you return to your NEPLAN scheme and call the element that should be set. On its menu tab...

In my opinion this is inrush current in the primery side of transformer. This is 2-nd or 5-th harmonic, but it's important to know how many periods is this 2000Amps?

- fireproof concrete; - asbestos (worst part is that it is carcinogenic and banned it to how I know); - poleoretanova fireproof foam. Good luck!

You are right. I am also meditated on the subject, and soon I was facing the same dilemma. The question is what you want to measure and what information you need? You say you want to measure the harmonic components of the voltage, over voltage transient spikes ... Once you want to measure over...

Who is the differential relay manufacturer?

Dear Sirs, I'm also in the IEC world and I use always IEEE/ANSI numbers for relay protections and automation. There is a difference between IEEE/ANSI and IEC, you can see below.
