IEEE 43-2013 PDF
Remember me for one month. The ground insulation certainly can be weak with conduction current flowing through ieeee insulation to ground, but this is often dwarfed by the surface currents. It is recommended that subsequent ac high-potential testing not be conducted until the winding is fully discharged.
See Annex A for the use of other values. 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.

Copyright Compu-tecture, Inc. Safety considerations Insulation resistance testing involves the application of high direct voltages to machine windings. The ieee structure includes boards for operational areas as well as bodies representing members in the 45 Societies and technical Councils and ten worldwide geographic regions.
C, and taken at a specified time t from start of voltage application.
I T — Total current: Enter your personal account email address to request a password reset: To find out if ieee leakage current is mainly a current or also contains the more damaging conductance current through the volume of the insulation to ground, one must do a step voltage test or ramp test to a test voltage one is comfortable with given the level of megohms measured.
IEEE and its members inspire a global community through IEEE’s highly cited publications, conferences, technology standards, and professional and educational iede. Poluicao em Isoladores Artigos sobre Poluicao em Isoladores. Get a Quote Careers Exhibitions.

IEEE is led by a diverse body of elected and appointed volunteer members. From this formula, ieee is very clear that the insulation properties drop precipitously as the temperature rises, and we all know what happens to over-heated motors.

For test voltages V and above, the lead between the test set and the winding must be appropriately insulated and spaced from otherwise, surface leakage currents and corona loss may introduce errors in the test data.
Megohm measurements may be tracked over time to help determine when a motor or generator should be reconditioned.
Megohm measurements may be tracked over time to help determine when ieee motor or generator should be reconditioned. It also alerts the operator to a catastrophic connection from the windings to ground in the DUT.

IEEE is led by a diverse body of elected and appointed volunteer members. Clause 1 and Clause See information below on minimum megohm levels. The discharge current manifests itself in two components:. Land Use and Development. 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.
Sustainable Development Goals and standardisation, how do they connect?

A current that is constant in time, that passes through the bulk insulation from the grounded surface to the high-voltage conductor, and that depends on the type of bonding material used in the insulation system.
