So we have come back from the auction with our old “new” machine, placed it where we want it, now we look around for an electrical point to connect the machine. We see a space at the board closest to us and excited call the electrical holesaler(not a typo).
Is it the product causing the pollution they are talking about or is it that the product is limited to these environments, I don’t know? You check it out:
Wow, this could be a real bugger to find for the electrician… When the starting torque required is very close to the available rated starting torque of the motor… Aaahhh, YES OFFCOURSE, In star we drop by 0.58 percent and that relates to a third of the available torque and voila there the motor sits […]
Shooo, another relay revelation I never expected…operating temperature 52-55DegC just with the coil powered. “Our products are designed to safely work way above the rated values”, the manufacturer says.
I bet you did not know Lovato does DC contactors? No, not just that you can get a DC coil operated version – but the actual load can be a DC load!! Ok, but as with everything – it has to be used “in moderation” and it will work just fine. A few rules apply […]
Hi guys, How many people know how to reset a circuit breaker? Just push it up you say
Why did I not think of this… In another post I wanted to elaborate on the issue of a motor starting currents killing the generator so will it help to install a soft starter or might a star/delta starter be adequate? In the mean time I cannot resist sharing this trick: Since it is currently […]
Customer wants to install a current or rpm monitor for a motor is convinced it will not work with a star delta starter. The startup time is too long, by the time delta pulls in it would have tripped.
I connected but it does not work, what am I doing wrong?
Nice anecdote to explain power factor in electricity.
The relay requires an auxiliary supply to operate the electronics then we are going to connect the current “reading” phase to the current measuring input terminals. These might or might not be isolated from each other
We all know what happens to an electrical device if it was exposed to any energy source much higher than its own rating…the same applies to circuit breakers. Cascading / coordination does two things: It ensures that every device downstream in an electrical reticulation will never be exposed to any energy higher then its own […]
I walk into the workshop and I see someone testing a solid state relay, but he is using the digital meter to confirm if the output is switching. I walk up and ask what are you doing? I notice the solid state relay is a 3-30Vdc input control and the output is a 230Vac output, […]
This guy is upset…”5 of your sensors I installed and not one of them is working”. I still try and ask ..”What is the product number”…he says “No, I don’t know and I don’t care, I am coming there now, I am bringing this rubbish back now!”. “Uhhh” is all I can get in when […]
