The minimum megohm reading for motor windings is typically considered to be 1 megohm per kilovolt of operating voltage, with a general guideline suggesting a minimum of 1 megohm for low-voltage applications. However, for many applications, a reading of 2 megohms or higher is preferred to ensure reliable insulation. If the reading falls below these thresholds, it may indicate insulation degradation, warranting further investigation or maintenance.

Can 3 pH induction motor rotates if its 1 winding get shorted?
If one winding of a three-phase induction motor gets shorted, the motor may still operate, but its performance will be significantly affected. The shorted winding can cause an imbalance in the magnetic field, leading to reduced torque and efficiency. In some cases, the motor may overheat or get damaged due to the increased current in the remaining windings. Therefore, while it might rotate, it is not advisable to operate a motor with a shorted winding.
Why winding temperature not measuring directly?
Winding temperature is often not measured directly due to the challenges associated with placing sensors within the winding itself, which can be intrusive and affect performance. Instead, indirect methods, such as measuring the temperature of the housing or using thermal models, are employed to estimate winding temperature. This approach minimizes disruption and allows for easier monitoring while still providing accurate temperature assessments. Additionally, indirect measurements can help in assessing temperature changes over time without interrupting the operation of the equipment.
What wll happen if the starting winding in a split pase motor fail to energize?
The motor would not start rotating. The motor will just hum and the rotor will be stationary. If you can get the rotor to start turning the motor will still run on its run winding.I have a cement mixer that has a motor with a burnt out start winding. All I have to do is turn the barrel and the motor will start turning over. Without the start winding you have a choice of which way the motor will turn. If I turn the mixer barrel the opposite direction, the barrel will turn that way until I turn the unit off.
What will happen to the reading on the ammeter if one bulb blows out?
If one bulb in a series circuit blows out, the circuit becomes open, and the current stops flowing. As a result, the reading on the ammeter will drop to zero since there is no current passing through the circuit. In a parallel circuit, if one bulb blows out, the current may decrease slightly due to the change in total resistance, but the ammeter will still show a reading corresponding to the remaining bulbs in operation.
Why latching current is more than holding current in thyristor?
Holding current is a kind of Imin i.e., a minimum rating current which should not be decreased less than this limit so that SCR will be off(Maximum limit).Whereas latching current is again a limit which is Imini.e., a minimum current that should be there to make it on(Minimum limit).So obviously Holding current is more than latching current.If u still have the confusion go through the link below ALi RAZA

Why a two winding transformer is used instead of single winding transformer?
You need two windings because that is the purpose of the transformer - to convert one voltage into another. If there were only one winding, it would be an inductor, or a special case called an autotransformer, but that is still "sort of" two windings.AnswerThe major advantage of a two-winding transformer (a 'mutual transformer') over a single-winding transformer (an 'autotransformer') is that a two-winding transformer provides electrical isolation between the secondary and primary circuits. This is very important for safety reasons and there are many circumstances in which the use of an autotransformer is not permitted.
