Avoiding corrosion in electrical systems | Consulting-Specifying Engineer
I like the use of 24hr project cameras. Makes sense.
Did you know that horse-power is roughly equal to KVA (kilo volt-amps) throughout most motor sizes? The actual motor KVA will vary based on motor efficiency and other variables but its close enough for a quick calculation. This can be quite helpful when trying to figure out how much power you need to supply a large quantity of motors. And someone needs an answer in say…..less than a minute. Just add up your HP, convert to KVA. (If you want to convert to 3 phase amps well just divide by line voltage and square root of 3). Try throwing some numbers around in your next project meeting and see if it works.
