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.

Georgia Power makes the SMRT choice with Megger
Power utility companies operate nationally important critical infrastructure and thus face considerable regulatory compliance issues. Testing power system elements like relays and current transformers under these rules is a time consuming and costly operational expenditure. In a bid to streamline its testing operation, Georgia Power deployed new relay test sets from Megger. For their test engineers, the results speak for themselves.

Motor testing with MTO106
Winding resistance measurements are conducted for detecting various faults in transformers – including shorted turns, loose connections, broken strands, and malfunctioning tap changer mechanisms. Winding resistance test sets such as the MTO106 are also capable of testing electric rotating machinery – motors and generators. Winding resistance measurements detect problems in a motor that other tests may not find. These problems include partial or fully shorted coils, poor crimps/connections, imbalance between phases (improper turns on a phase), and incorrect coil (phasing) connections.
