There are many factors that determine what the leakage current will be. You could find out what the insulation winding resistance of the new motor should be and use the 660 volts and Ohm's law to calculate the current. If you measure this using a DC insulation tester however it probably will not yield an exact measurement since the test is not under normal operating conditions, but is a DC voltage test. To get the best measurement you really need to test the motor under operation and use a leakage clamp on the ground connection to see what the current really is since other factors come into play such as the insulation resistance, imbalance and frequency. An example of a tool would be the Fluke 1630 or Fluke 360.
mA (thousandths of an Amp.)
A ground leakage can damage electrical appliances. When there is a current leakage, it causes the appliance to draw more current through thecircuit, hence produces excess heat. This can damage the appliances.
Because the space charge region or depletion region is small in germanium compared to silicon hence leakage current is more in germanium than silicon
The GFCI is measuring leakage current to ground, so if no current is flowing it won't trip.
we call them ground fault breakers 10 milliamps thru you instead of the normal current path can kill you if you have a neon test lamp connect it to one of the hot leads and earth the other. if it lights the earth leak detector is faulty. if it opens the breaker its good most here in the usa have a test button
it takes the lowest resistance path back to the current source Answer: Earth leakage current flows down to earth through the consumer earth continuity conductor.
In low voltage and electronics Leakage Current is any current that flows when the ideal current
The current of the minority charges (collector region) is the source of the leakage current. At higher temperature, this leakage current increases due to increase in thermal energy.
leakage current itself
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
by measuring the insulation resistance then by usig the formula for finding leakage current leakage current =voltage applied /resistance measured by megger.
There are several formulas to find out leakage current, but one is the general electric current equation. This electric current equation is I=Qt.
A ground leakage can damage electrical appliances. When there is a current leakage, it causes the appliance to draw more current through thecircuit, hence produces excess heat. This can damage the appliances.
In low voltage and electronics Leakage Current is any current that flows when the ideal current is zero. In medium and high voltage applications it is the current that flows either through the body or over the surface of an insulator. Leakage current often arises when outdoor insulation is submitted to conductive fog (sea mist/spray, industrial smogs) or when a pollution layer containing soluble salts is formed on the insulator surface and then wetted, for example by dew or mist. These currents can reach several hundred mA and may lead to flashover of the insulation.
The maximum allowable leakage current for any electrical device is 0.5 mA. This is equivalent to 0.5% of the rated current. This is a safety requirement to ensure that any current leakage is minimal and will not cause any harm to the user or damage to the device.Maximum allowable leakage current: 0.5 mAEquivalent to 0.5% of the rated currentIt is important to adhere to the safety requirements to ensure the safety of users and the protection of the device.

Flow of current in the collector circuit produces heat at the collector base junction. This increases the temperature. More minority carriers are generated in base collector region, since more bands are broken,the leakage current increases. In other word, leakage current increase when temperature increase.
