Dear Sirs,
Two question, if it's possible.
1. Motor can be supplied or directly through network (380 V), or through the frequency
regulator.
We have not enough experience in latter case, but if we apply directly MCSA approach for this case, the number of faults is relatively low.
Do you have...
Dear Sirs,
can you help me in questions of the influence of input voltage distortion
(THD and odd and even harmonics) on SPMS operation? What levels of those
quantities is acceptable? What harmful consequences is due to high voltage harmonic level?
What literature (books, standards and...
We often see "pin holed" inner steel water pipes in buildings
(corrosion from the inner side of pipe).
If it is possible, some questions on this item.
1. Can the AC current on internal pipeline systems of buildings...
Who can explane, why the inner water pipes in building became "pin-holed"?
May it be due the AC electrical current flow on this pipes or exist another reasons?
What must be done in this situation?
Thanks in advance.
