Six Pulse Converter with Interphase Transformer: The basic connection of a Six Pulse Converter with Interphase Transformer is shown in Fig. 3.38. This is obtained by connecting two three pulse…
Six pulse midpoint converter: The converter transformer converts the existing three phase system to a six phase one, since it has six secondary windings. The Six pulse midpoint converter connections…
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…
Two pulse mid point converter: Two pulse mid point converter are, in general, single phase converters. The pulse number of the converter indicates the frequency of the ripple voltage superimposing…
Polarised Relay: This Polarised Relay is very frequently employed where operation is required in two directions. In a d.c. Polarised Relay contact A is closed when current in the operating…
Different Types of Relays Elements: The Important Different Types of Relays Elements or also called Electromagnetic Types are Induction Disc Relay Induction-cup Relays Moving Coil Relays Hinged Armature Relays Polarized…
Influence of Static Protective Relays: Influence of Static Protective Relays on the associated equipment like current transformers, voltage transformers, etc,. Let us discuss one by one. Current Transformers: Burdens on…
Surge Voltage and its Distribution and Control: The design of power apparatus particularly at high voltages is governed by their transient behavior. The transient high voltages or surge voltages originate…
