I am looking to solve for the source sequence impedance of an x utility. This is what I've done so far.
Parameters:
3-phase utility contribution = 7708 A
1-phase utility contribution = 7708 A
Base/Rated MVA = 100 MVA
Base Rated Voltage(L-L) = 117875 V
X/R...
Good morning all!
Not really sure where to stick this topic in the forum categories. Sorry for any inconvenience. I am curious as to how scripting is performed on Doble's new Protection Suite relay testing program. Please advise.
Although the metric unit of energy is the joule, heat is commonly also measured in units called calories (there are about 4.19 joules in a calorie), or in larger units called Calories (note the capital C). A Calorie is 1000 calories, and should always be called a kilocalorie.
During the site outage we performed metering checks on a GE489 relay. The software we used to download AsFound (AF) settings was EnerVista. After everything checked out, we downloaded the settings (AsLeft) and compared them. We found no changes.
On a separate occasion we compare the setting...
Hello all!
I want to start this threat because of significant and potential problems caused by compatibility between Dell Latitude and GE Relays. I experienced multiple occasions where clients call back asking why we change settings on their relays, when in fact we compare the settings in...
