When measuring the Insulation resistance of a motor winding (winding to earth) using a megger meter, Applied voltage(1000V) was automatically reduced to 500V. and the measured insulation resistance values are also very low (in Kohm range) Can anyone give me a reason???

1879I have a relay contact rated at 220v dc which is supplied with a 24vdc from the panel,for it to trip the dampers(24vdc).What if the application of the relay changes so that it should work at its rated 220vdc then will it work at 24vdc supply given or any other consideration needs to be taken .....
2103A resistance, inductance & capacitance are connected in series between points A & B.The voltage drops across the resistance,inductance&capacitance are found to be 40V,70V&100V respectively. What is the total voltage between between points A&B (Vab)? a)210V b)70V c)50V d)230V
