Megger Circuit Diagram: Another common method of measuring resistances above 50 M Ω is the Megger Circuit Diagram (megaohmmeter) shown in Fig. 10.23(a). This instrument is used to measure very…
Two phase AC Servo Motor: For a low-power (a few hundred watts) control application, a balanced Two phase AC Servo Motor is ideally suited as it can be driven by…
Synchronous Generator Ratings and Loss Dissipation: The Synchronous Generator Ratings and Loss Dissipation is its operating voltage, frequency, speed and kVA/MVA output at a specified power factor. In case of…
DC Motor Losses and Efficiency: The Losses and Efficiency of a transformer have been studied in earlier lesson. As in the case of transformers, it is more accurate to determine…
Different types of losses in transformer: The transformer has no moving parts so that its efficiency is much higher than that of rotating machines. Different types of losses in transformer…
Real Transformer On Load Condition | Equivalent Circuit: Figure 3.11 shows a Real Transformer On Load Condition. Both the primary and secondary have finite resistances R1 and R2 which are…
Types of Rotating Electric Machine: The Types of Rotating Electric Machine are namely the dc machine, the polyphase synchronous machine (ac), and the polyphase induction machine (ac). Three materials are…
