Three pulse midpoint converter: These are basically three-phase converters, and are very popular because a 3-phase supply is readily available. 3-phase converters have a greater power capability than single phase…
Electric Converter: Electric Converter - The speed of a dc motor can be varied by varying the armature voltage or the field current, for which a variable dc supply is…
Types of Protective Relays: Basically, Types of Protective Relays are analogue-binary signal converters with measuring functions. The variables such as current, voltage, phase angle or frequency and derived values obtained…
Static Relay: The term 'static relay' is generally referred to a relay incorporating solid state components like transistors, diodes, resistors, capacitors, etc. In this type of relay, the functions of…
DC Motor Speed Control: In the foregoing sections we discussed the torque-speed characteristics of dc motors, bringing out the effects of armature voltage variation and field current on them. The…
Basic Components of Electric Circuit: The Basic Components of Electric Circuit consists of three parts: (1) energy source, such as battery or generator, (2) the load or sink, such as…
AC Input: The, ac input modules that are commonly available work with 24, 48, 110 and 220 V. It is important to use the one that fits the needs based…
Detectors Types: The Detectors Types are as follows For low frequency, the most convenient detector is the vibration galvanometer. For ordinary laboratory work at frequencies up to a few 100 Hz,…
