Scanner Feature for the BITE2 and Power DB
If a scanner is used to scan a battery bar code the battery string name will be saved in the data file. A bar code can be created with a string name.  This is then scanned into the BITE2 receiver, using the bar code reader. When the data is transferred to Power DB the string will display the bar code, during the download.

Testing Batteries with 2mm Access Ports
Batteries can present an arc hazard due to their exposed terminals (posts). If a non-insulated tool should fall across these terminals the resulting arc flash can injure people in the vicinity as well as damage equipment. This is why insulated tools should be used when working on battery strings. This is also why some batteries have caps covering their posts. These caps are removed during testing.

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.

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).

Expanding the Diagnostic Impact of Power Factor Testing - Interpretation of Narrow Band Dielectric Frequency Response
The Narrow Band Dielectric Frequen-cy Response (NBDFR) test method consists of a series of power factor measurements ranging from 1 to 1000 hertz. This aggregate of the CHL (pri-mary to secondary) measurements constitutes the dielectric response of the test specimen. The subsequent evaluation consists of a geometric analysis of a plot where the mea-sured power factors and correspond-ing frequencies are graphed. As an insulation system ages, the response migrates towards the high frequency end of the plot. When the frequency corresponding to the lowest magni-tude within the response (the trough) is used as a reference point, the move-ment of the response may be quanti-fied; enabling the transformer may be classified in terms of condition.

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.
