What is constructional differences and features single and three phase transformer?

The major difference is that the core, usually having three limbs if it is a 'core-type' core (or five, for a 'shell-type' core), must accommodate six windings: three primary phase windings and three secondary phase windings. Some three-phase transformers may have additional windings ('tertiary windings', for example) for various other purposes.


What happen if single phase supply give to two phase and one phase is earthed of three phase transformer?

Nothing good. This could lead to core saturation (core is sized for flux flowing from three phases 120 degrees out from eachother) which would cause large currents to flow into the transformer. Depending on the primary and secondary connection type (Wye or delta), voltage readings would be strange. To give real specific answers, more information is needed (core type, autotransformer, three winding, voltage of primary and secondary, winding connections, phase relationship (such as Ydn), etc.).


How the voltage is induced in a single phase transformer?

The changing magnetic flux in the iron core of the transformer induces a voltage in the windings.


What will happen if apply two phase supply to a three phase transformer?

A three phase transformer is simply three transformers so, supplying one phase to a set of three transformers will result in only one phase output. Any loads connected to that transformer that are expecting three phase power will malfunction, and could fail.AnswerA three-phase transformer is NOT 'three separate single-phase transformers', as suggested in the original answer. It is a single transformer with three primary and secondary phase-windings wound around a common three-limb ('core') or five-limb ('shell') core. If a single-phase supply was applied to one of the three primary windings, then single phase voltages would appear across each of the three secondary windings and the remaining two primary windings. These voltages would not be out of phase with each other.


What is the formula of 2 phase power?

The formula which are needed for making of a single phase transformeri.e o/p voltage,watt,current,turn,core size,coil number,bobin size etc

Processes of copar as a strategy for community development?

The processes of COPAR as a strategy for community development are the following: # Pre-Entry Phase # Entry Phase # Organization Buildingg & Capability Building Phase # Sustenance & Strengthening Phase # Turn-over & Phase-out Phase Pre-Entry Phase * In this phase of COPAR, the community organizer's activities are comprise of two major tasks; the site selection and, selection of host families or the staff house. Entry Phase * Also called as the Social Preparation Phase. Here, the community organizers immerse themselves in the selected site and integrate in the community. The major tasks of the community organizers include the ff.; conduct information campaign about the programs, conduct deepening social investigations, identification of potential leaders that will be made members of the community health organization, make provisions for health programs, and conduct a community diagnosis to determine the problems of the community that affects health. Organization Building & Capability Building Phase * This phase signals the start of community self-management on the development program and the formation of the Community Health Organization a.k.a. CORE GROUP including their training to become partners in community health development. Susthenance & Strengthening Phase * I this phase, the Community Health Organization are already participating in community wide health programs including the delivery of the basic health services specially in areas where health facilities are not available. Implementation of livelihood programs is important in this phase of COPAR as profit from this will help the Community Health Organization to finance their planned health programs and this is true if financial assistance are not available from the government and private sectors. Turn-over & Phase-out Phase * The phase of COPAR to when the Community Organizers leave the community to stand alone and deepen their commitments to pursue their goals of being self-reliant.

What keeps inner core in the phase?

The high pressure at the center of the Earth keeps the inner core in a solid phase, despite the extreme temperatures. The pressure prevents the iron in the inner core from melting, maintaining its solid structure.

What is the piece of evidence used to determine the phase of the core?

The primary piece of evidence used to determine the phase of the Earth's core is seismic waves. By studying how seismic waves pass through the core, scientists can infer information about its composition, temperature, and state (solid inner core, liquid outer core).


What is the difference detween single phase and three phase transfomer?

The construction of the core is different. Most 'core-type' three-phase transformers have three limbs. Additionally, there are three sets of primary windings, and three sets of secondary windings.

What fuses during the red giant phase?

During the red giant phase, hydrogen fusion occurs in the shell surrounding the helium core. The core is no longer fusing hydrogen, as it has already converted most of its hydrogen into helium. This causes the outer layers of the star to expand and cool, leading to the red giant phase.
