Abstract - The main objective of the research project is to
1.2 Symmetrical Fault
create a simulation model for three-phase symmetrical (Triple Line to Ground) and asymmetrical (Single Line Fault, Double Line Fault) analysis using MATLAB. These faults, which include single-line-to-ground, double-line-toground, triple-line-to-ground, and line-to-line faults, typically occur in long transmission line systems. Several fault types are analyzed and the results are shown in the simulation output, such as voltage and current. This study examines the MATLAB program used to simulate transmission line modalities.
A symmetrical fault is one that affects every phase while keeping the system in balance. A symmetrical fault is one that occurs in three phases. These three fault types are appertained to as unsymmetrical or asymmetrical faults line to base, line to line, and two-line to ground. Symmetrical faults can be examined using per-phase analysis since they produce balanced conditions.
2. CAUSE OF ELECTRICAL FAULT
Key Words: Line to line fault, Line to ground fault,
There Are Several Reason of Electrical Fault -
1. INTRODUCTION
• Short Circuits Equipment damage and system dislocation can affect from the creation of a low- resistance route that allows inordinate current inflow.
Double line to ground fault, symmetrical and asymmetrical faults, MATLAB software
• Voltage Unbalance Considerable variability in phase voltages may affect in outfit imbalance and possible malfunctions.
Fault analysis is helpful in determining the machine voltage and line current when colourful faults do in the system. The terms" line voltage" and" line current" are pivotal when dealing with an electrical system. There are substantially two types of faults in the electrical system. A symmetrical fault is the first type and an asymmetrical fault is the alternate, similar as a single line- to- ground fault, a line- to- ground fault, a double line- to- ground fault, or a two- line fault (1). assaying power line faults is important from the point of view of electrical system protection. We use a three- line circuit swell and relay system to cover the electrical system.
• Challenges with Grounding Wrong or shy grounding ways could contribute to crimes. • Environmental Factors Lightning strikes and other rainfall- related events can beget faults in outfit and lines of electricity.
3. OUTCOME OF ELECTRICAL FAULT Power outages, outfit damage, fires, and short circuits are just a many of the issues that can affect from electrical failures. They might be the consequence of effects like damaged sequestration, imperfect wiring, or broken outfit. These troubles can be reduced with routine examinations and proper conservation.
1.1 Asymmetrical Fault These are veritably common and less serious than symmetrical faults. These faults are generally known as three types videlicet single-phase earth fault also known as LG fault, two phase short to each other and current fault also known as line to line (L- L), two phase earth fault also known as double line. to ground (L- L- G) blights. Line- toearth fault is the most common fault and 64- 69 of faults are of this type. This causes the line to communicate earth or ground. 14- 20 percent of faults are double lines to base and beget two cables to communicate ground. Line- toline faults do when two cables meet, substantially due to line swinging caused by winds, and 5- 10 percent of faults are of this type.

4. CIRCUIT AND DESCREPTION Fig. 1 illustrates how the simulation of different faults is enforced using a simulation model created in the MATLAB software exercising the Sim Power System. It consists of one three- phase source along with one two- winding three- phase motor. One three- phase VI dimension and one R- L cargo is also connected to each other by a transmission line. Three- phase faults do between the three- phase VI dimension and the motor line for voltage and current fault measuring purposes. compass connected
