Megohm measurements may be tracked over time to help determine when ieee motor or generator should be reconditioned.
There were no books found for the applied search filters. The insulation resistance of a rotating machine winding is a function of the type and condition of the insulating materials used, as well as iere application technique. 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.

A current that is constant in time, that iede through the bulk insulation from the grounded surface to the high-voltage conductor, and that 43-2103 on the type of bonding material used in the insulation system.
They were placed on your computer when you launched this website. The association is chartered under this name and it is the full legal name. In particular, this standard describes typical insulation iee detected ieee the insulation resistance test.
Who knows, maybe no better ifee all? For large machines with high capacitance, isee inrush current can be high. This current is usually zero if the motor is new or undamaged. Search book title Enter keywords for book title search.
Land Use and Development. 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.

It is recommended that subsequent ac high-potential testing not be conducted until the winding is fully discharged. IEEE and its members inspire a global community through IEEE’s highly cited publications, conferences, technology standards, and professional and educational activities.
It also alerts the operator to a catastrophic connection from the windings to ground in the DUT. There were no books found for the applied search filters.
These can only be obtained from the manufacturer of the motor. I T — Total current: Who knows, maybe no better at all? 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. No items in cart.

IEEE is the world’s largest professional association dedicated to advancing technological innovation and excellence for the benefit of humanity. 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.

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 dc voltage tests procedures for the measurement ieee the insulation resistance and polarization index of insulated stator, and rotor windings and how to interpret the results are ifee in this recommended practice.
IEEE is led by a diverse body of elected and appointed volunteer members. Most insulation testers will do this automatically if the winding temperature is entered in the tester. Are you sure you want to empty the cart? 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 IEEE Brand Identity Toolkit iree the basic usage rules for all corporate identity elements and how to utilize them to create a powerful and consistent communications pieces. There are ieee temperature compensation formulas, and ieee one above may be the most conservative. 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.
