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 Transformer App note
The is capable of performing turns ratio tests on any phase shifting transformer by allow-ing for phase shifts to be entered with respect to the secondary winding. But with all of the differ-ent ways phase shift is expressed, how do you know if the entered phase shift value is correct?

Advances in Modern Instrument Controls: The Evolution of Insulation Tester Equipment
The original design of electrical test instrumentation was often focused on taking a measurement and little else. A lot of the operation and interpretation was left to the operator. This was fine for people who liked the challenge or had experience. But it could be tough on apprentices, new hires, and those who were simply handed the instrument with no training.Constant improvement in instrumentation has addressed these problems by adding to the capabilities of the instrument. Some are for convenience, some safety and some the advancement in technology over the years that helps standardize testing and provide more accurate results. A prime example is that of insulation testers. Let’s examine some of the key improvements in features and functions, and what they mean to the operator.
