I am looking for a transmission protection and Control training in Canada or US. Someone refered me to this course offred by Univirsitry of Wisconsin. Has anyone attended this course who can provide a feedback?

Thank you
One of our customers is upgrading their electrical system by replacing a 2.5MVA transformer to 5 MVA transformer ( 27.6kV primary). I am wondering if there is a CEC requirement to install a breaker on the primary side of the new transformer instead of a disconnect switch?
Thanks for all feedbacks
We are designing a 230kV substation and wondering if there are any code/standard requirements in Canada to provide certain horizontal distance from de-energized parts a 230kV substation equipment ( such as A-Frame) to the substation fence?
We are building a small substation ( including a transformer and a padmount switchgear) in adjacent to a wind farm substation and connecting the new substation ground grid to the existing grid. The existing grid has a measured grid resistance of .5 ohms. we are using Cymgrd to model our...
We are working on a project and need to define typical ( conservative ) impedance values for Delata-Wye and Wye-G, Wye-G, Delta transformers. Transformers are 18/25/30 Mva 230kV/34.5 kV. Where can I find these typical values?
I apprecite your responces.
CEC suggests specific arrangements for underground cable installations in section B4. I am working on a design which specifies 6C/phase cables in 6 conduits.
Our preferred arrangement to accommodate installation flexibility is to have all phase-A, B and C cables installed in one duct bank...
We are new to consulting industry and am wondering how the 30-60-9% submittals are being defined?
I am referring to issuing engineering drawings for customer review.
Thanks
Our customer is going to use a switchgear to perform a paralleling function of two separate sources. these are utility sources and there is no gen. involved.
They intend to use voltage sensors with 3% mag. tolerance and 1 deg. phase angle error.
There are no info on slip frequency data.
What are...
We are developing a review & approval process for engineering work within our company. I like to know what procedures other companies currently use. I appreciate your inputs.
We are working on a design project in Canada and part of it is to specify medium voltage cables. We are told that all cables must be rated to 125% of full load current of transformers. CYME simulation shows that cable ratings are OK; however this has created confusion as whether we must follow...
I am working on a cap bank application in a medium voltage system in Canada. Does the canadaian code ( or a local province code)require a disconnect switch infront of the breaker for maintenace reasons?
We have a Dyn5 ( 25kv /480V)2.5 MVA transformer and a switch on the HV side. We need to apply a reverse power relay on the system to trip the breaker incase power is reversed. There isn't any PT isntallaed on the HV side and it's not possible to do it either. If we accomodate installing CTs and...
I am moving to management/leadership role and I need to have more training on the subject matter. I live in Toronto, Canada and am looking for an institute (private/college/university) that offers these courses.
I appreciate any feedbacks on training institutes who offer these courses.
I ran a study using SKM software,results show Cat2 for data given at 80% of the maximum fault level as a worst case senario.( Incident energy was calculated 6.2 cal/cm2)
The tcc curve of the fuse does not clear the cat#2 PPE curve after 1 second,however the same fuse clears cat#3 curve for 2...
Beside using a current limiting fuse in series with standard E type fuse( K type can't be used) on primary side of a transformer ( 10MVA, 28KV), is there any other solution to limit the fault through current?
Thanks
