My question pertains to the codes for the United States, namely the NEC.
I currently have a project where I need to accomplish the following:
Generator - AC Distribution Panel - Load 1 / Load 2 / Load 3
Basically I am employing a 200kW, 600V, 3-phase, 4-Wire Generator in a substation for...
I work for a company that designs & builds power substations. Our substations typically have control buildings and one of the items inside are relay panels. We have a panel shop who manufactures our relay panels as well as install all devices on the panel such as relays, lockout relays, test...
Let me say first off thank you to all that have responded. Your input has been very helpful.
It took a couple of your threads but it suddenly clicked for me as to why the voltage regulation at the end is important.
You can't lose more voltage along the line than your LTC can bring back up...
I don't know anything about how the voltage is to be regulated.
This is a bid project and the customer is simply proposing several combinations of Transmission Line Sizes and MW on the line.
And from that, I was calculating the Voltage Drop.
My answer came out to be 10%, which seems high to...
I was recently asked and performed a percent voltage drop calculation for a transmission line.
I have never done this calculation before so prior to submitting my work to the customer, I wanted to see if my answer was acceptable.
The only problem is I can't find any literature that lists what...
I work for an engineering company that does substation design. I wanted to know if there is a rule of thumb when to used shielded cables for power & control cables. I've heard anytime the voltage is 230KV or above, shielded is required. Can anyone verify this. Thanks.
