IEEE and its members inspire a global community through IEEE’s highly cited publications, conferences, technology standards, and professional and educational activities. When IR is tracked over time, resistance values must be temperature compensated and the temperature must be above the dew point 34-2013 comparisons of results to make sense. These can only be obtained from the manufacturer of the motor. From this formula, ieee is very clear that the insulation properties drop precipitously as the temperature rises, and iees all know what happens to over-heated motors.

You can change your cookie settings through your browser. Regardless of the cleanliness of the winding surface, if the winding temperature is at or below the dew point of the ambient air, a film of moisture may form on the insulation surface, which can lower insulation resistance or polarization index. See Annex A for the use of other values. Valid Buy this standard.

Safety considerations Insulation resistance testing involves the application of high direct voltages to machine windings. After 1 minute with a random wound DUT, or minutes with a form wound DUT, this is typically the only current remaining unless the insulation is weak ieee dama There may be an increase in the surface leakage current on machines where a stress-control coating has been applied to the end-windings.

What’s new in the IEEE 43 insulation resistance testing standard? | EASA

Insulation Resistance IR is maybe the most common motor test. Enter your account email address request ieee password reset: No items in cart. Note that these tests can be done to voltages lower than the normal DC Hipot ieee voltages to find out if there is ieee current.

This current is usually zero if the motor is new or undamaged. 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.

Land Use and Development.

For large machines with high capacitance, the inrush current can be high. The association is chartered under this name and it is the full legal name. The IEEE Brand Identity Toolkit explains the basic usage rules for all corporate identity elements and how to utilize them to create a powerful and consistent communications pieces.

IEEE is the world’s largest professional association dedicated to advancing technological innovation and excellence for the benefit of humanity. After the applied direct voltage is removed, a suitable discharge circuit should be provided see Clause 4.

What’s new in the IEEE 43 insulation resistance testing standard?

This time interval is based on the R resistiveL inductiveC geometric capacitiveand absorptive characteristics of the circuit during charging time of the application of the voltage and discharging elapsed time since the removal of eiee voltage source and subsequent grounding of the winding under test. The governance structure includes boards for operational areas as well as bodies representing members in the 45 Societies and technical Councils and ten worldwide geographic regions.

The quotient of the insulation resistance at time t 2 divided by the insulation resistance at time t 1. Who knows, maybe no better ifee all?

It is recommended that subsequent ac high-potential testing not be conducted until the winding is fully discharged. The ground insulation certainly can be weak with conduction 43-2103 flowing through ieeee insulation to ground, but this is often dwarfed by the surface currents. Get a Quote Careers Exhibitions. Clause 1 and Clause See information below on minimum megohm levels.

The dc voltage tests procedures for the measurement of the ieee resistance and polarization index of insulated stator, and rotor windings and how to interpret the results are described in this recommended practice.

Who knows, maybe no better at all? There were no books found for the applied search filters. Land Use and Development.

The safety measures described are by no means exclusive.

The discharge current manifests itself in two components:. The insulation resistance of a rotating machine winding is a function of the type and condition of the insulating materials used, as well as their application technique.

Iewe will often go directly to a Hipot ieee 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.
