4. Case is wide corrugated
5. Case is provided with radiators
there are mony type of cooling of t/r
1- natural air cooling
2- oil cooling
3- water cooling
4-blast air cooling
To be very brief, Harmonics are caused because of magnetising current flowing in the primary of transformer, which cause deaviation from the ideal sinusoidal waveform producing peaky currents in the primary. Due to this the core of the transformer gets saturated and the wave form produced in the secondary also gets distorted.
This is 3 Nos Two Winding Transformers put together to form of Three Phase transformer, HV is Star Connected & LV is Delta Connected in the LV phase is leading by 30 Degree with respect to HV phase
An industrial generator has some form of built-in cooling system. A marine generator relies on pumping water from the lake or ocean the vessel is in for cooling.
A center-tapped transformer and two diodes can form a full-wave rectifier that allows both half-cycles of the AC waveform to contribute to the direct current, making it smoother than a half-wave rectifier. This form of circuit saves on rectifier diodes compared to a diode bridge, but has poorer utilization of the transformer windings. Hence we do not use centre tapping for full wave rectification.Ashish sharmaAstt. ProfessorHIET, Shahpur, kangra(H.P.)
The no-load current of a transformer is the current which is drawn from the source at rated voltage and frequency even when no actual load current is being supplied.The no-load current is what must be drawn to overcome the inherent and unavoidable losses of the transformer's components. Those losses comprise the primary circuit's resistance (known either as the "copper losses" or as the "resistance losses") and the transformer's magnetic reluctance (known either as the "iron losses" or as the "magnetic losses").Reluctance is the techical description given to the energy necessary to excite the magnetic circuit and overcome its hysteresis, the effects of eddy currents, etc.For more information see the Related link shown below.
transformer is a static device hence it needs form factor.
CT=========current transformer PT=========potential transformer these are the instrumental transformers.
Most modern systems use a fan for cooling. Some systems, particularly those that have been overclocked, use water cooling or even a form of refrigeration. These methods are expensive and quite inappropriate for general use.
The singular possessive form for the noun table is table's.
TTR = Transformer Turns Ratio
You could put the equation in slope-intercept form or in parent linear function or even make a table of values.
plz answer
Cooling
What is the the table of the teacher make in the possessive form
Pews such as chromium,nickel,and lead, pb, ores form within cooling
No. Igneous rock forms from the cooling of magma.
no . they come from rapid cooling lava
