Power Problems
Dear Mr. Baker,
Greetings from the soggy soon to be frozen Eastern Wilderness,
We had a simular problem at the mine where I once worked.
They had gotten out so far underground that the line drop was greater than the marginal 6 volts ac they were used to using for 4160 volts 60 cycle 3 phase power.
They ended up installing a bank of regulating transformers on L1,
L2, and L3 to regulate the transmitted voltage. they did not have to worry about the continuity as it was independant and fed from
the switch gear at the work sites in the mine.
Maybe that is something to consider?

Use Regulating Transformers.......
Hello Izaharis: Thankyou very much for the helpful information from the real world out there, much appreciated.
A VERY GOOD TIP.

You are most welcome, I have found this forum to be very incitefull and informative. ■
Caution: Diesel Power
Portable Diesel Driven Screeners: Care must be taken to ensure CONSTANT power on portable units.
Diesel power if it fluctuates will of course cause the hydraulically driven screener or other devices to temporarily LOAD UP with a surge load and start to carry fines over inefficiently.
This of course applies to diesel driven anything, screeners, crushers, stackers.......
......................
line power: Believe it or not.......there are numerous times when FULL ELECTRIC LINE POWER into a quarry is NOT CONSTANT and this will in effect REEK HAVOC on your screening circuit and crusher circuits if the power is not constant.
Of course if the electric power is not constant, then the screener will slow down momentarily and this causes big problems which at first glance are NOT READILY identifiable. I had this happen with great DISCUSSION to this final conclusion with a big aggregate account. After all options were eliminated we actually called in the HYDRO ELECTRIC suppliers who identified the problem as theirs.....causing our equipment to look like it was not performing up to par.
Have any of our visitors had this problem.........we would like to hear about it.
THANKS.......BUZZING ALONG.............George ■
