Auto Transformer Starter - Working Principle, Advantages and Disadvantages: In auto transformer starter method the reduced voltage is obtained by taking tappings at suitable points from a three phase auto-transformer,…
Tap Changing Auto Transformer: Fig. 15.6 shows diagrammatically Tap Changing Auto Transformer. Here, a mid-tapped auto-transformer or reactor is used. One of the lines is connected to its mid-tapping. One…
Autotransformer | Definition | Use of Auto transformer: So far two-winding transformers have been discussed wherein the windings are electrically isolated. When the primary and secondary windings are electrically connected…
Three Phase Auto Recloser vs Single Phase Auto Reclose: Three Phase Auto Recloser is one in which the three phases of the transÂmission line are opened after fault incidence, independent…
Types of Auto Reclosing: Types of Auto Reclosing can be broadly classified in two categories: Medium voltage auto-reclose where continuity of supply is the principal aim. High voltage auto-reclose where…
Armature Voltage Control using Transformer: Variable voltage for the dc motor control can also be obtained by either using an auto-transformer or a Armature Voltage Control using Transformer with tappings…
Delayed Automatic Gain Control: Delayed Automatic Gain Control: Simple AGC is clearly an improvement on no AGC at all, in that the gain of the receiver is reduced for strong…
