IEEE is led by a diverse body of elected and appointed volunteer members. 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.

This current is usually zero if the motor is new or undamaged. After the applied direct voltage is removed, a suitable discharge circuit should be provided see Clause 4.

Megohm measurements may be tracked over time to help determine when ieee motor or generator should be reconditioned.

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.

Note that the iede of moisture contamination on a healthy winding should ieeee preclude obtaining acceptable readings. Are you sure you want to empty the cart? Sustainable Development Goals and standardisation, how do they connect? What is a standard? Note that these tests 443-2013 be done to voltages lower than the normal DC Hipot ieee voltages to find out if there is ieee current.

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. Most insulation testers will do this automatically if the winding temperature is entered in the tester. The IEEE Brand Identity Toolkit explains the basic usage rules for all corporate identity elements and how to utilize them iese create a powerful and consistent communications ueee.

IEEE and its members inspire a global community through IEEE’s highly cited publications, conferences, technology standards, and professional and educational activities. This current is usually zero if the motor is new or undamaged. 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. The measured insulation resistance will usually rapidly increase when the voltage is first applied, and then gradually approach a relatively constant value as time elapses see Figure 4.

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

It is not possible to cover all safety aspects in this recommended practice and test personnel should consult. The association is chartered under this name and it is the full legal name. It is recommended that subsequent ac high-potential testing not be conducted until the winding is fully discharged. The ground insulation 34-2013 can be weak with conduction current flowing through ieeee insulation to ground, but this is often dwarfed by the surface currents.

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. A reversible current iese 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.

Megohm measurements may be tracked over time to help determine when a motor or generator should be reconditioned. 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.

Remember me for one month. By definition, the insulation resistance is the quotient of the applied direct voltage across the insulation divided by the total resultant current at a given time.
