We will be implementing this protocol at our substation and I would like to know what are some of the pitfalls to avoid.
Currently we use GE and SEL relays but we may move to Siemans and Abb since they seem to be the most versed in using 61850. We will be installing a redundant secure ethernet...
Why do the voltage vectors rotate 180 deg. when the ground is moved from the neutral to say phase 2. This is for wye connected phases??? Can't seem to wrap my head around this one. Thanks.
Looking for if any relay testing requirements for power generation companies. Not sure if they are covered by NPCC or NERC. My initial thought is they are not.
Thanks in advance for any info.
Can anyone explain why you would ground the middle phase on the secondary of a CCVT metering circuit. I have come across this in substations where generators are located and also old substations where there is no generator. Thanks for any response in advance. The CCVT feeds metering and...
We are investigating the installation of FACTs technology to stabilize the grid and we are looking into DVAR, Statcom, and TScs. Anyone have any expericence with any of these types of MVar control systems? I'm sure we would all like to hear from you so we can benefit from your experience...
