I am looking for ideas to have a relatively inexpensive and simple hardware device that can be sent to the field to test an Ethernet port for proper TCP port connection rights.
Application is to pre-test and verify router, switch and firewall rules have been properly setup for a device, with...
Looking for advice and recommendations on properly allocating KW and KVAR losses across multiple transformers sharing a transmission line and then further allocate each transformer line loss share to its related resources/feeders under each transformer.
Assumptions -
1. Three transformers...
I’ve watch several Two-Wattmeter Method videos, including this series (3 parts starting with this one) and I have some questions to take the topic a bit farther and to better understand the vectors, specifically when CTs and PTs are in the mix. Furthermore, my confusion and frustration relates...
I used to use an HP41C calculator years ago. I am now studying to take PE and dusting off my RPN skills with a HP35S (NCEES approved). Can anyone tell me the pros/cons of using equations versus programs; when best to use either method? Also, does anyone have a good resource of POWER equations...
Need help with help with NGR rating for Option#1 re: EPRI Technical Brief_Effective Grounding and Inverter-Based Generation. How to properly calculate current through NGR when connected to neutral of Wye winding of Wye-g/delta(not a zig-zag) grounding transformer. What is valid impedance model...
I have a wind farm generation & tie-meter design where the meter location is at a wind farm and the point-of delivery for LBA and PPA settlements is several miles down a radial 345kV transmission line (at bus of transco). A few loss compensation questions have come up. Line loss only, no...
I am replacing a older Form 45S (Elite) meter with a Form 5S (SEL734/5) type meter in a 69kV substation using SEL's recommended Form 5 wiring method.
The application is measuring power on a wye-grounded side of transformer. The meter has two (2) dedicated CTs. There are three (3) PTs...
