Types of Magnetic Leakage Flux in Induction Motor: The Magnetic Leakage Flux in Induction Motor is that flux which links only the stator or only the rotor windings. Because of the presence of air-gap in…
Centrifugal Pump Load: Centrifugal Pump Load are used as boiler feed pumps and for pumping water in water pipe lines. The former must be adapted to the variable output of the steam generator. In the…
High Voltage Laboratory Rating: The High Voltage Laboratory Rating and size of test equipment chosen in the h.v. laboratories depends on the test facilities to be provided. Normally, the design of the laboratories for 230…
Key Diagram of Substation 66/11KV: Fig. 25.10 shows the key diagram of a typical 66/11 kV sub-station. The Key Diagram of Substation can be explained as under: 1. There are two 66 kV incoming lines…
Three phase Fully Controlled Rectifier Control of DC Separately Excited Motor: Three phase Fully Controlled Rectifier Control (6 pulse) fed separately excited dc motor drive is shown in Fig. 5.32(a). Thyristors are fired in the…
Common Collector Characteristics of BJT: In the Common Collector Characteristics of BJT circuit arrangement of Fig. 4-31, the collector terminal is common to both input CB voltage and output CE voltage. Using this circuit, the…
What is Transistor Transistor Logic (TTL) Circuit? Texas instruments introduced transistor transistor logic (TTL), a widely used family of digital devices in 1964. It is fast, inexpensive and easy to use. Transistor Transistor Logic family…
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 the main considerations are of…
Voltage Divider Bias Circuit: For the self-bias circuit, it was seen that increasing the resistance of RS brings ID(max)Â and ID(min)Â closer together, but that increased RS values result in lower ID levels. As will be demonstrated,…
Types of Motor Enclosures: In order to protect machines against the ingress of dirt and dust or larger foreign bodies like spanners, vermin etc. into it, it is desirable that some suitable enclosure be provided.…
