how we control automatic generator i'e with to supply (main supply and local generator) when the main supply was break to supply the local supply automatically to begin supplying power.I now this control circuit is the combination of contactor time delay contactor switch and overload relay .but my question is how we combine those component thank you
HOW TO WORK A VFD?SAY SIMPLE METHOD
I'm generating a pulse of 3V with frequency 80Hz (12.5ms time period) and pulse duration 0.125ms and feeding it to a transformer since i want the pulse to get amplified around 60V. At the output amplification s happening but the pulse is changed to a spike, can you tell me what could be the reason? (an ordinary transformer 220V-12V stepdown transformer is reverse connected ie. now it is 12V-220V stepup and voltage amplification happens)
