Voltage -Current Relationship of Circuit elements.

Voltage Current Relationship of Circuit elements.
1- Circuit Elements components Resistance, Inductance & Capacitance.

Please follow Link given below to find out Voltage Current relationship of Circuit elements-

Capacitance

Capacitance is the capability of an element to store Electric Charge within it. A Capacitor store Electric energy in the form of Electric field being established by the two polarities of charges on the two electrodes of a Capacitor.

*Quantitatively capacitance is a measure of charge per unit Voltage that can be stored in element.
               C=q/v
q=amount of charge that can be stored in a Capacitor of capacitance.
V= Potential Difference Voltage

*Capacitor Never Dissipates energy and only store it.it can store finite amount energy ,even if the current through it is zero.

Unit of Capacitance- Unit of Capacitance is Farad(F).

Inductance/Circuit Inductance

Inductance is the property of a material by Virtue of which it oppose any change of Magnitude or direction of Electric Current passing through the conductor.

* Inductance is said to be one Henry when Current through a coil of Conductor Change at the rate of one ampere per second inducing one volt across the Coil.

* Unit of Inductance-  Henry(L)

* It is given by Faraday's laws of Electro-magnetic induction.

Why Short Circuit test of Transformer Performed on HV (High Voltage) Side

Short Circuit Test of Transformer Performed on HV Side
This can be illustrated by Considering a 3300/220 V , 33 KVA Single Phase Transformer.
Short - Circuit Test on the h.v. side, The instrument ranges are 165 V(2 to 12 % of Rated Voltage of 3300 V), 10 A(Rated Current) and 10 A,165 V, Which are well within the range of the ordinary instruments.

On the other  hand, instrument ranges  for a Short Circuit  Test on l.v. Side  are 11 V ,150 A,  and 150 A,11 V . The instruments of Such ranges and Auto Transformer capable of handling 150 A , may not be Readily available and the same time , the results may not be so accurate. It is the reason Short-Circuit tests are conducted on h.v. Side.

Why Open Circuit Test Perform on Low Voltage(L.V) Side & High Voltage (H.V) Side Open in Transformer

Open Circuit Test Perform on Low Voltage -Side, -
Open Circuit Test Perform on
l.v.Side.Consider 3300/220 V, 33 KVA , Single Phase Transformer.
Range of Voltmeter, Ammeter & Wattmeter are 220 V (Rated Value), 6 A(2 to 6 % of Rated Current of 150 A) .
And 6 A,220 V Respectively. These are Standard Ranges for ordinary instruments and Therefore more accurate Reading Can be Obtained .
If Open Circuit Test Perform on The h.v. Side ,a Source of 3300 V may not be Readily available.At the Same Point Instruments Range are 3300 V & 0.4 A.
3300 V which are not within the Range of ordinary instruments & The Results obtained may not be accurate.it may not safe to work on high Voltage Side.

Resistance

Resistance is Property of material by Virtue Oppose the flow of Electron. Thus Resist the flow of Electric Current.
Unit of Resistance- Ohm'S

Any Wire Resistance offer when Current flowing in Wire & Potential Difference( V) Applied across wire .

*Resistance find out by Apply Ohm'S Law.

* V- IR.
    R- V/I

Why Transformer Rating in KVA.

Transformer Rating in KVA.

1-KVA is Rated Output is Limited by Heating hence Losses in the Transformer.
2- Mainly Two Type Losses in Transformer.
    1-  Core Losses .
     2- Ohmic Losses.
1- Core Losses Depends on Voltage.
:Core Losses Find out by Transformer Open Circuit Test Perform.
2- Ohmic Losses Depends on Current.
 : Ohmic Losses find out by Transformer Short Circuit Test.

* So Losses Depends on Voltage (V) & Current (A) is almost unaffected by Load power factor.


So Transformer Rating in KVA.

33 KV Line ko kaise pahchane/How to identify 33 KV Line.

 33 KV Line ko pahchane ka tarika
1- V-Cross arm Dekh Kar
2 - Pin Insulator Dekh Kar.
3- Conductor Dekh Kar.
1- V Cross arm ka weight jayada hoga 11 KV Line ke V- Cross arm se & V-Cross arm ke beech Space 1525 mm hoga.
2- Pin insulator 10 KN ka hoga. 
3- Conductor ka area Nominal 100 Sqmm ka hoga. Aur Sectional area jayada hoga jis se Conductor ki current carrying capacity 257-291 A (Dog Conductor) hogi.

Yis tarh se 33 KV Line ko pahchane sakte hai.

What is Transformer

Transformer is a Static Device That Transformer Electrical Energy from one Circuit to another Circuit through the medium of Magnetic field.
Transformer is  Electrically Separate but Magnetically Coupled. Coupling magnetic field allow Energy transfer from one Circuit to another Circuit.

Transformer Principal- Transformer work on Mutual induction.
Transformer Rating uses in Distribution Network- 16 KVA, 25 KVA,63 KVA, 100 KVA,200 KVA.
