Can someone please recommend a PF meter that will work on 11 KV delta feeders (about 6400 v per phase)? Some of our generators are reading a low power factor (80-85%). But because the generators are switched around to feed different feeders, it would make sense to correct our PF at the feeders...

We have several motors labelled only "240v 60hz 3-phase" These motor are made in USA - an industrial floor standing band saw, band sander, dimpling machine, etc. and name plate doesn't say if thats delta or wye. I assume the motors are actually 240v delta, since thats a standard voltage in USA...

We have a problem with relays tripping at our power plant. We believe it may be due to transients but need to make accurate measurements to be sure. Our current SCADA software (Siemens WinCC) measures 16 points at our power plant, every 500 milliseconds. I asked the SCADA "expert" why we cant...

My company wants to purchase some EE design software. Does anyone have any experience or recommendation about ETAP or SKM or any other design software? Is ETAP getting to be the most popular? We want something that can connect at our power plant and record and analyze transients there causing...

Has anyone tried a cast resin transformer? Like these Link And what is their advantage over previous types of transformers?

Coal plants have used supercritical heaters for along time, and now even "ultra-supercritical" coal power plants are in operation. Nuclear power plants are stuck at the theoretical stage for supercritical power? Whats the bottleneck?

how do i use a HP crystal detector such as the 470 [also called the 8470] these have an input side which is type N or apc-7, and their output side is BNC. But the HP scalar network analyzers and power meters [like the HP 435 or 436] all have an input which is 7-pin DIN. so can't i use these...

I did a keyword search and unfortunately Wiltron stuff isnt common here. But im looking for these Wiltron [or compatible] things: 1. my wiltron 401 power meter has a BNC input. I have BNC to N and BNC to sma adapters. I need a power detector that works in the 2-4 ghz range, 2. my wiltron 610...

I want to make my own attenuator - would this work or what should I change? /-------100 ohm resistor-------ground / input----/ \ \ \-------1 ohm resistor--------output i will make each lead length = wavelength/2 is it do-able like this? :)
