Answer / rizwan

cube root means x^(1/3)... so its a case of x^n
so if u want to take the cube root you use the block "pow".
which has u^v.
means the number and its power as 1/3
i.e
x^(1/3)
so your first input will be the number
and the second input will be its power.
hope you will find it useful.

To test Transformer we give HT side 440V to see wheather that it is producing 17.6V on LT to verify Voltage ratio is correct or not but when we give the 440V voltage to LT side then what will happen to HT voltage ?

I have a shop heater with a 1/3 hp capacitor start, induction motor driving the fan. Intermittently, the fan motor speeds up significantly for several seconds (15-60 sec) then slows to normal operating speed. The manufacturer suggested changing the capacitor which made no sense, but I did it to no avail. Could this possibly be caused by the centrifugal switch intermittently reconnecting the start winding?
