A guide to conductor resistance testing of rotating machine stator with MTO106
Measuring the DC conductor resistance of a rotating machine stator can reveal a lot of information about the machine. It is always desirable to find out the existence of any resistance that is higher than the nameplate value which might be caused by poor joints, corrosion or mechanical deformation of the stator winding.

DC test of vacuum integrity in MV switchgear
Since the 1950’s vacuum has been used as insulation media in switchgears. Even though that technology has proven to be very reliable, over time air will leak into the vacuum chamber and degrade the insulation. Also, a good practice is to measure after transport or accidents. The accepted way to test the vacuum integrity has always been through a voltage withstand test. For field tests DC test is preferred due to the weight andsize of the instruments.

TTRU3 Phase Shifting Transformers
The TTRU3 is capable of performing turns ratio tests on any phase shifting transformer by allowing for phase shifts to be entered with respect to the secondary winding. But with all of the different ways phase shift is expressed, how do you know if the entered phase shift value is correct?

Railway Bonding
In the UK, we have two common power systems supplying locomotives. A 25 kV overhead line system and a 750 V third rail system. Both systems use the track as a return path for current flow (see figures 1 and 2).
