I believe I posted this in the wrong forum previously. I've been trying to get cost estimates for a transformer. Specifications for the transformer are as follows: outdoor rated (NEMA appropriate enclosure), 630kVA, 50Hz, 11kV(delta)-415V/240V(wye), pad-mounted, oil-filled.
Shipping or...
Does anybody have a good source to determine the cost to purchase a 6030kVA/11kV-415V/50Hz, outdoor rated transformer? I don't have access to my RS means. Thanks in advance.
I am working on a project to expand the electrical distribution from a power plant to add a feeder for some loads. I went to the existing electrical distribution to determine configurations and voltages. What I observed on the nameplate of the transformer was something I haven't come across...
I've recently taken over a position for someone who has left. We are required to do random inspections on electrial panels installed and maintained by a contractor. I've been reading through past reports and saw a discrepancy that was noted for a particular panel. It stated that unlocked...
We have a contractor submitting a cable that he is requesting our approval on. The load is rated for 300A so he submitted submitted a 300mm^2 (1 run, all phases and neutral in one cable). The voltage is 380V. This cable is to be buried directly in earth and concrete-encased in a electrical...
We tested a small, 3-phase, dry type, 20kVA transformer that is delta to wye and 1000V/416/240V. We took a multimeter and measured from from Phase A to ground and phase B to ground on the low side and measured 416V. When we measured from phase C to ground we measured 0V. This told me that...
I am currently in Iraq doing some QA/QC on some electrical work being done for the Iraqi army. While determining the total load of the camp, the contractor is utilizing what's known as a diversity factor (DF) for each building and secondary distribution panel. I did some research and kind of...
I need to do a power quality analysis on a 120/208V panel box and main breaker. I'm trying to determine the amount of harmonics on UPS dedicated loads and commercial power loads in the building and do a load assessment on the commercial powered loads.. Due to the critical purpose this building...
Now I just finished reading this thread: 238-4843. If I read correctly is it to be understood that even though a generator may be rated at 1000kVA (we'll use 4160V) can not be run at 1000kW at a pf of 1? I thought that PF basically showed you how much of your current was being used for work...
I have a TTR in our shop and I would like to give a class on how to use it. I know in my mind how it works but I would like to be able to give a class in a more understandable way. Something pretty basic. I know you have some that measure exciting current and phase angle difference from HV...
