What is the primary side?

The primary side is the side of the valve formed from the initial branching of the raphe sternum during raphid diatom ontogeny.

How do you convert primary impedance to secondary?

When moving the impedance from the primary to the secondary, we divide it by the turns ratio squared.

What is primary and secondary side?

Primary is incoming supply while secondary is outgoing supply.

What is meant by HV and LV side of transformer?

The transformer’s high voltage side carries high voltage and low current. The transformer high voltage side winding having more turns than the low voltage side. The conductors of the high voltage windings have a lower thickness than the low voltage side.

How do you find CT?

The CT ratio is the inverse of the voltage ratio. In this example, the voltage ratio is 1:5, so the CT ratio is 5:1. This means the current level is stepped down 5 times where, if the primary current is 200 amps, the CT output is 40 amps.

How do you obtain the approximate equivalent circuit of a transformer is referred to the primary?

R2′ = K2R2 and X2′ = K2X2 . The following figure shows the equivalent circuit of transformer with secondary parameters referred to the primary. Now, as the values of winding resistance and leakage reactance are so small that, V1 and E1 can be assumed to be equal.

Why flux in primary and secondary winding is always equal?

flux produced in primary winding will pass through the secondary winding, so generated flux in primary winding will be same as in secondary winding. Flux is directly proportional to the Ampere-Turns not proportional to the turns ratio (N).

When all the quantities are referred to the secondary side?

Equivalent Circuit When all the Quantities are Referred to Secondary side. The equivalent circuit diagram of the transformer is shown below when all the quantities are referred to the secondary side. Circuit Diagram of Transformer When All the Primary Quantities are Referred to Secondary Side.

What is the primary and secondary side of a transformer?

For this tutorial we will define the “primary” side of the transformer as the side that usually takes power, and the “secondary” as the side that usually delivers power. In a single-phase voltage transformer the primary is usually the side with the higher voltage.

What is the difference between primary and secondary parameters?

If the equivalent circuit parameters are referred to as the primary. The secondary parameters must be divide with the transformation ratio K except for the secondary current where it multiplied. If the equivalent circuit parameters are referred to the secondary.

What is the primary equivalent of the secondary circuit?

The primary equivalent of the secondary e.m.f., The equivalent circuit can further be modified by transferring R o and X o ( exciting circuit ) towards the left end known as the approximate equivalent circuit as shown in the figure below. The error introduced by doing so is small and can be neglected.
