Optimizing Transformer Parameters for Efficient Substation Performance | Tims

AI Thread Summary
The discussion revolves around determining sensible parameters for a $100 million transformer in a substation, including nominal capacity, average repair cost, unsupplied energy cost, and average repair time. Suggestions for nominal capacity include 10^5 KW, while average repair costs are debated, with some proposing $1 million as more realistic. Participants recommend researching typical costs for 500/230 kV transformers and provided a link to a relevant document. There is also a suggestion to contact a knowledgeable user for further insights. Overall, the conversation focuses on establishing realistic parameters for transformer performance and costs in substations.

Hi All,

I am required to assume some parameters for my research,
For a new transformer worth $100 million for a substation, what likely could be sensible for these

parameters?

Nominal Capacity? (Example 10^5 KW)
Average Repair Cost? ($1 million ?)
Unsupplied energy cost? ($3 kWh ?)
Average Repair time? (1 year?)

Thanks,
Tims

Google substation costs for a typical 500/230 kV transformer and

Would $1 million (CAD) be more realistic than $100 million? Would this configuration produce a capacity of 10^5 KW?
 
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'
I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
