WHAT IS THREE-PHASE POWER? 2 3. Three-phase power is a common method of alternating-current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electric grids worldwide to transfer power.
Power Measurement In a Three-Phase System (on photo: Traditional power meter) For temporary measurements, a single wattmeter can be used. However, for permanent measurements, a three-phase wattmeter having two elements is used which indicates both balanced and unbalanced loads. You can write a book review and share your experiences. Other readers will always be interested in your opinion of the books you've read. Whether you've loved the book or not, if you give your honest and detailed thoughts then people will find new .
Various methods are used for measurement of three phase power in three phase circuits on the basis of number of wattmeters used. We have three methods to discuss: Let us discuss one by one each method in detail. Here, it is applied to three phase four wire systems, current coil of all the three wattmeters marked as 1, 2 and 3 are connected to.

Programmed instruction is a systematically planned, empirically established and effectively controlled instructional technique Author: Harshvardhan Singh. Three-Phase Electrical Power addresses all aspects of three-phase power circuits.
The book treats the transmission of electrical power from the common sources where it is generated to locations where it is consumed. At typical facilities where electrical power is used, the book covers the important topics of grounding, currents, power, demand 3/5(1).
Programmed instruction for library use is an example of how new theories of behavior and learning were incorporated into bibliographic instruction. Programmed instruction was based on the theories of psychologist B.F. Skinner, and began to be used for library instruction in the early s.
In essence, it was a self-teaching method. nuts-and-bolts of programmed instruction and not its relation to the science, but a brief discussion is necessary with respect to one of the critical components of programmed instruction-the frame.
A frame is the basic analytic unit with which programmers work. Programs, for example, are. A three-phase system can be connected to a load such that the amount of copper connections required (and thus the transmission losses) are one half of what they would otherwise be.
Consider three single-phase systems each supplying W to a load (Figure 3). The total load is 3 x W = Size: 1MB. In the s and s, PLATO (Programmed Logic for Automated Teaching Operations) was the first computer system which was used for programmed instruction (Lockee et al.
Programmed. The goal of early developers of programmed instruction was to design the instructional activities to minimize the probability of an incorrect response (Beck, ). However, much has Programmed Instruction Three-Phase Power and Its Measurement 16 book made of the distinction between what some have called Crowder’s () multiple-choice branching versus Skinner’s linear-type program.
The power of discrimination and making immediate and effective responses is developed through such instruction. Programmed instruction material helps teachers to devote more time for creative work since they can be fed from jobs like drill and practice routines.
A programme is not a human being and hence can be used atany time of the day. o Direct Instruction (Demonstrations & Presentations) o Anxiety Reduction o Programmed Instruction o Simulations The following list provides definitions for a variety of different methods, including most of those listed above (Cruikshank, Bainer & Metcalf, ).
Every method has advantages and Size: KB. The instructions provided by teaching machine or programmed text book is referred to as programmed instruction. According to J E Espich and Bill Williams, “programmed instruction is a planned sequence of experiences, leading to proficiency, in terms of stimulus- response relationship that have proven to be effective.
Fig. Three phase power measurement circuit under unbalance condition Connect the circuit as shown in Fig. Replace the ganged rheostat by three separate rheostats of 26 Ω, A and connect in a star.
Adjust the three rheostats at the maximum values. Switch on the supply and set the autotransformer to V. a technique in which the teacher deletes words or other structures from a passage and leaves blanks in their places.
The students then fill in the blanks by using the surrounding context to determine the missing material. It can be used as a method of instruction a means of testing or a method of estimating reading ability. Series programmable power sources.

Go back to Three phase power measurements ↑ Wye and Delta comparison. The Wye configuration is used to distribute power to everyday single-phase appliances found in the home and office.
Single- phase loads are connected to one leg of the wye between line and neutral. When doing measurements on a three-phase power installation, the power in all three phases must be measured simultaneous to become the total power.
For this there are three commonly used methods who are described in this article. One wattmeter method. Fig. 1: Connection diagram to measure the three-phase power with one wattmeter.

noun. Education. a progressively monitored, step-by-step teaching method, employing small units of information or learning material and frequent testing, whereby the student must complete or pass one stage before moving on to the next.
Historically, this mode has its roots in programmed instruction. However, when properly deployed it is far more flexible than any book- or material- based programmed instruction.
For one thing, in tutor mode, the material can be presented interactively, and dynamic graphics and other sophisticated teaching aids can be integrally used.Programmed learning (or programmed instruction) is a research-based system which helps learners work method is guided by research done by a variety of applied psychologists and educators.
The learning material is in a kind of textbook or teaching machine or medium presents the material in a logical and tested sequence. The text is in .programmed instruction, method of presenting new subject matter to students in a graded sequence of controlled steps.
Students work through the programmed material by themselves at their own speed and after each step test their comprehension by answering an examination question or filling in a diagram.
