WebAs a result of grounding the phase B output of the PT, the WattNode meter will only report voltage, current, power, and energy for two phases: phase A and phase C. Blondel’s theorem explains that the sum results ( PowerSum …
Web6 feb. 2006 · A megger is testing insulation integrity, usually in Megohms. Continuity in ohms, often less than 10. Not all meggers have this feature. You may have to use a multimeter. L7- L8- L9 Continuity (Resistance between any two wires in this group will be twice the resistance between L1- L4, L2- L5, or L3- L6.) L1- Gnd Megohms. WebUse a motor with a 1.25 or 1.35 service factor instead of a 1.00 or 1.15 service factor. Provide additional cooling by forcing air over the motor. Figure 4. Over cycling is the process of turning the electric motor on and off repeatedly, increasing the temperature of the motor, and destroying the motor insulation.
Web17 jan. 2013 · I. Between phase and neutral. II. Between phase to earth. III. Between neutral to earth. With the other ends of the circuit conductor open the value should be infinity for all the test. If the value is zero there is short circuit or the insulation of the wire is damaged and the wire is changed accordingly. FOR CABLES:- WebSet your multimeter to Ohms. Start by completely disconnecting the spindle motor from all power sources. Check each wire, including T1, T2, T3 and the ground wire. If the reading is infinite, your motor should be fine. If you get a zero reading or any continuity reading, you have either a motor problem or a cable problem.
