• Introduction
• The project is designed to develop automatic
  mechanism off for a transmission line project
  automatically resets the result after a short
  break, in a temporary fault events as it remains
  capable of switching off in the event of
  permanent failure.
• Three phase transformers are wired in star input
  and star output having input 220 volt and output
  at 12 volt.

Transmission line fault

• Fault types include
• Single to ground (LG)
• LINE TO LINE (LL)
• FIRE FAULT (FF)

5
Comparator

• Op amps comparators look very similar
• But a comparator gives a logic output indicating
  the relative potentials on its two inputs
• An op amp amplifies the differential voltage
  between its two inputs and is designed always
  to be used in closed-loop applications

6
Relay

• It is a electro magnetic switch
• Used to control the electrical devices
• Copper core magnetic flux plays main role here

7
A double channel relay module is an electronic
device that provides a way to control two
separate circuits using a single module. The
relay module consists of two relays that can be
activated independently to switch the state of
their respective circuits.
8
A thermistor temperature sensor module is an
electronic device that measures temperature by
using a thermistor, which is a type of resistor
that changes its resistance based on the
temperature of the surrounding environment.
9
Copper wire is a type of electrical wire that is
made from copper, a highly conductive metal.
Copper wire is used in a wide variety of
electrical applications due to its excellent
conductivity, high ductility, and resistance to
corrosion
10
A jumper wire female to female is an electrical
wire that has a female connector on both ends,
allowing it to connect two components or devices
with male pins or headers. The female connectors
typically consist of metal pins surrounded by
plastic housing that provides insulation and
helps to secure the connection.

WORKING OF TRANSMISSION LINE FAULT DETECTION
The working of a transmission line involves
transmitting electrical power or signals from a
source to a load, while minimizing power losses
and maintaining the signal quality. The quality
of the transmission line is determined by its
characteristic impedance, which is a measure of
the resistance, inductance, and capacitance of
the line.

• There are various methods for detecting faults
  in a transmission line, including
• Relay protection This method involves using
  protective relays that detect changes in current,
  voltage, or impedance in the transmission line.
  When a fault occurs, the protective relay sends a
  signal to a circuit breaker to isolate the faulty
  section of the line.
• Distance protection This method involves
  measuring the distance to the fault based on the
  time it takes for the fault current to travel
  from the source to the fault location. The
  distance is calculated using a device called a
  fault locator.
