Similar to feeder taps, covered in the last issue, transformer secondary conductors can be every bit as confusing. Let's take a closer look at 240.21(C) to help clear up any misconceptions. As with ...

Note: All Code references are based on the 2014 NEC. The NEC has separate sections for transformer feeder protection and transformer protection. Article 240 lists requirements for transformer feeder ...

Certain electromagnetic devices such as differential transformers are effective at translating the displacement of a magnetic armature into an AC voltage, which is a linear function of the ...

• LVDTs produce a linear electrical output directly proportional to the position of a movable ferrous core of nickel-iron alloy. • Two secondary windings in the LVDT produce identical output voltages ...
