One very important component of a power transformer is the on-load tap changer (OLTC). The principal of the Dynamic Resistance Measurement (DRM) was developed to analyse the switching process of OLTCs ...

Dynamic Resistance Measurement (DRM) is a new method which can be performed as a supplementary measurement in order to analyze the switching process of an on-load tap changer (OLTC) on power ...

Designed for use in conjunction with the company’s circuit breaker analyzers, the new LTC135 accessory power supply from Megger allows transformer load tap changers to be tested easily and ...

Michael Krüger examines new diagnostic tools for power transformers. Due to ever-increasing pressure to reduce costs, the power industry is forced to keep old power facilities in operation as long as ...

This compact and intelligent instrument can perform many routine and advanced tests such as winding resistance (WR), dynamic resistance measurement (DRM), turns ratio (TR), frequency response of stray ...

Arlington, VA-based JEDEC Solid State Technology Association, a developer of standards for the microelectronics industry, on Monday announced the publication of JEP173: Dynamic On-Resistance Test ...

You might think the probes in the picture are just funny looking alligator clips. But if you watch [tomtektest’s] recent video, you’ll learn they are really Kelvin probes. Kelvin probes are a special ...

Designers often use a current shunt to measure low current being sourced out of their power supply since many of today’s power supplies do not offer adequate accuracy from their built-in measurement ...

The simplest model of a battery comprises an ideal voltage source that connects in series with a resistance whose value—often a few milliohms—depends on the battery’s electrochemical condition and ...
