Skelly interview prep Flashcards
Factors to consider when sizing LV cables
Be able to withstand a short circuit:
Depends on fault current amount, insulation of the cable, the time duration of the fault
Current carrying capacity:
Must be able to deliver the expected load current
Voltage drop across cable:
Cable has some resistances and reactances causing a voltage drop, should remain within an acceptable limit to ensure connected equipment function properly (i.e motor)
Insulation material:
Air cables require UV and mechanical protection, also protection against heat and moisture
What is Ohms Law?
Current and voltage are directly proportional (linear graph) -> resistance is constant i.e resistor. An example of a non-ohmic component is a filament lamp evident from the I-V graph
What kind of activities you expect to do on a daily basis while working at Skelly
Provide the clients of the company with technical support through each phase of development from design to construction to operation. I also expect to liaise with stakeholders such as investors and contractors. Design electrical systems used in building projects such as alarms, implementing sensors across the rail building such as fire alarms, replacing legacy infrastructure such as gas pumps with more renewable ones like electrical ones
Why do you want to work for us? What do you know about the job?
Company values such as sustainability
High profile projects such as the battersea arts centre and cambridge central mosque
My skillset and knowledge from not only my electrical engineering degree but also my key interest in sustainability (solar simulation projects). Also my experience working and leading in a team environment can prove useful.
Describe the skills you learnt in your plumbing work experience
Learnt how waste management systems are designed in residential buildings and their requirements (p-traps)
Learnt how to solder copper piping to repair leaks (abrasive to sand down the connection, apply flux, heat the pipe, apply the solder around)
Turn off water supply through stop valves
Different materials used in waste systems such as ABS and PVC and how to properly prime PVC to ensure the glue properly adheres.
Liaised with clients to make sure they understood the scope of the project (how long it would take)
