Hello all,
I have a question regarding the IPB in connection with completely enclosed Generator switch gear. Might be a little confusing.
The IPB data shows the average temperature rise of 50K at the ambient temperature of 40°C. At the generator circuit breaker terminal, the contacts have an...
Hello Dennis,
Thanks alot for acknowledging my email and for your clear explanation.
Most of your assumptions are correct. The switch gear will be installed on a concrete slab. doesnt know the exact gap though but your assumption seems reasonable.
Your assumption of boy being ventilated is...
This is not transformer.. It is a switchgear that is placed outside and the 50°C is just a value that is assumed. But some areas in middle east has been recorded around 50-55°C of ambient temperature for some days.
Hello all.
I have posted this question in Thermodynamics forum and I am posting here again to get some opinions by electrical engineers who might have experience with similar situation as mine.
My question is to estimate the amount of temperature rise inside the enclosure due to solar loading...
Thanks alot for the responses.
I want to explain a little more clear about my calculations.
The switchgear is tested with 12.5kA of rated current at 40°C of ambient temperature. according to standards we are allowed to have a 65K of rise inside the switchgear cubicle. this value is mainly...
Hello all,
I have already gone through the threads in this forum related to Solar gain, Temperature rise. I have got enough Information but some how stuck with unrealistic values through my calculations. I hope some you you can help me in this.
My question is ,to estimate the amount of...
