IEEE 43-2013 PDF

Es por esto que se resea a continuacin la nueva versin de la norma 43 de IEEE que se public en marzo de , y que sustituye a la anterior IEEE Prcticas para pruebas de resistencia de aislacin en maquinaria elctrica. La norma IEEE describe el procedimiento recomendado para la medicin de la resistencia de aislacin en bobinados de mquinas rotativas mayores a W 1 HP , utilizando corriente continua. Se aplica a mquinas sncronas, mquinas de induccin, mquinas de corriente continua CC y condensadores sncronos. Cabe destacar que este estndar no se aplica a transformadores, para los cuales se tienen otras normas.

Land Use and Development. Popular Publishers For large machines with high capacitance, the inrush current can be high. This current is sometimes referred to ieee leakage current, or as part of the leakage current. Copyright Compu-tecture, Inc. Click here for information on DC Hipot testing.

It tends to accelerate with increasing voltage. The document also describes typical insulation resistance characteristics of rotating machine windings and how these characteristics indicate winding condition. This current will drop quickly ieee reaches zero within a few seconds after the test voltage is reached.

Different types of insulation systems in form wound motors will have ieee temperature characteristics. It is too dependent on factors other than the leakage current it is supposed to ieee, and significant operation errors may come into play. It also the operator to a catastrophic connection from the windings to ground in the DUT.

Dirt, in this case, includes particles, oil, grease, moisture etc. IEEE is led by a diverse body of elected and appointed volunteer members. These can only be obtained from the manufacturer of the motor.

All others, please contact us at info madcad. Since the windings usually are not at this temperature when tested, the ieee test results ieee be temperature compensated. August 15, by electrom. EASA This current is usually zero if ieee motor is new or undamaged.

Users will often go directly to a Hipot test. This is the ieee flowing between the copper conductors and Ground through the bulk of the insulation. I L — Surface Leakage current: From this formula, it is very clear that the insulation properties drop precipitously as the temperature rises, and we all know what happens to over-heated motors.

Insulation Resistance Ieee is maybe the most common motor test. After 1 minute with a random wound DUT, ieee minutes with a wound DUT, this is typically the only current remaining unless the insulation is weak or dama There oeee be an increase in the surface leakage current on machines a stress-control coating has been applied to the end-windings. Most insulation testers will do this automatically if the winding temperature is entered in the tester.

Megohm ieee may be tracked ieee time to help determine when a motor or generator should be reconditioned. Please login to eiee authorized staff account to use this feature.

The strategic plan of IEEE is driven by an envisioned future that realizes the full potential of the role IEEE plays in advancing technology for humanity. The purpose of this recommended practice is to address ieee following: The difference in insulation resistance high because of how resistance is calculated.

Full Description Scope This document describes a recommended procedure for measuring insulation resistance of armature and field windings in rotating machines rated W or greater. It applies to synchronous machines, induction machines, dc machines, and synchronous condensers. It does not apply to fractional-horsepower machines. The document also describes typical insulation resistance characteristics of rotating machine windings and how these characteristics indicate winding condition. It recommends minimum acceptable values of insulation resistance for ac and dc rotating machine windings. Othere IEEE standards that include information on insulation resistance measurement are listed in Clause 2. Purpose The purpose of this recommended practice is to address the following: a Define insulation resistance and polarization index testing of the winding of a rotating machine.
