5.1 Current Transformer (CT)
In power systems, current transformers are widely preferred to sense the current for control purposes. They offer several advantages compared to other types of current sensors. Firstly, they provide electrical isolation between control [r]

machines and partly to the lack of effective ways to measure power quality param- eters. However, in the last 50 years or so, the industrial age led to the need for products to be economically competitive, which meant that electrical machines were becoming smaller and m[r]

is called Lock-out/Tag-out.
A lock-out/tag-out procedure works like this: all individuals working on a secured circuit have their own personal padlock or combination lock which they set on the control lever of a disconnect device prior to working on the system. Additionally, they m[r]

The chapter starts with definitions of charge, current, voltage, and power, and with the introduction of the basic laws of electrical circuit analysis: Kirchhoff’s laws. Next, the basic circuit elements are introduced, first in their ideal form, then includi[r]

As noted previously, indoor environments pose signifi cant challenges for repeatable measurements. The nature and level of external interference is often completely beyond the control of the person carrying out the test, and can vary signifi cantly from one measu[r]

This book includes the coverage of basics of MATLAB and application of MATLAB software to solve problems in electrical circuits, control systems, numerical methods, optimization, direct [r]

The toughness of a steel increases with decreasing hardness. However, when certain impurities such as arsenic, phosphorus, antimony, and tin are present, a toughness minimum termed "temper embrittlement" may occur in the temperature range 350[r]

ULSD is stored in the same tanks and uses the same fueling systems previously used for regular diesel fuel. Currently, ULSD is available everywhere for highway use.
When switching to ULSD some fleets have changed fuel filters after two or three tanks of fuel because they have be[r]

As with many construction projects, it is often easier to build in a hierarchical fashion. Initially, we use the very basic building blocks to build slightly larger building blocks, and then from these larger building blocks, we build yet larger building blocks, and so on. Similarly[r]
