Insulation Resistance IR is maybe the most common motor test.
IEEE is the world’s largest professional association dedicated to advancing technological innovation and excellence for the benefit of humanity. The ground insulation certainly can be weak with conduction current flowing through the ieer to ground, but this is often dwarfed by the surface currents.
The dc voltage tests procedures for the measurement of the insulation resistance and polarization index of insulated stator, and rotor windings and how to interpret the results are described in this recommended practice. Print 1 2 3 4 5 page sstarting from page current page.
The strategic plan of IEEE is driven by an envisioned future iieee realizes the full potential of the role IEEE plays in advancing technology for humanity. Note that the effects of moisture contamination on a healthy winding should ieeee preclude obtaining acceptable readings.
After the applied direct voltage is removed, a suitable discharge circuit should be provided see Clause 4. Remember me for one month. All others, please contact us at info madcad. Valid Buy this standard.
Note that these tests can be done to voltages lower than the normal DC Hipot ieee voltages to find 432-013 if there is ieee current. Get a Quote Careers Exhibitions. Land Use and Development.

There were no books found for the applied search filters. A reversible current of comparatively high magnitude and short duration, which decays exponentially with time of voltage application, and which depends on the internal resistance of the measuring instrument and the geometric capacitance of the winding.

The surface leakage current may be significantly higher on large turbine generator rotors and dc machines, which have relatively exposed creepage surfaces.

iees Most insulation testers will do this automatically if the winding temperature is entered in the tester. C, and taken at a specified time t from start of voltage application.
See Annex A for the use of other values. Usually, for clean and dry rotating machine insulation, the insulation resistance between about 30 s and a few minutes is primarily determined by the absorption current.

The association is chartered under this name and it is the full legal name. This current is usually zero if the motor is new or undamaged. It is recommended that subsequent ac high-potential testing not be conducted until the winding is fully discharged.
