  3. 3. • An electrical substation is a subsidiary station of a transmission and distribution system where voltage is transformed from high to low using transformers. • Electric power may flow through several substations between generating plant and consumer, and may be changed in voltage in several steps.
  4. 4. It is an automatically-operated electrical switch. It operates both on “ON LOAD” and “NO LOAD” conditions.
  5. 5. The protective relay ensures the safety of the circuit equipments from any damage which might otherwise cause by fault.
  6. 6. It is connected between the line and earth so diverts the incoming high voltage wave to earth. Lightning arresters act as safety valves designed to discharge electric surges resulting from lightning strokes, switching or other disturbance .
  7. 7. Lightning arrestors directly connected at one end to the transmission system.
  8. 8. Bus-bars are merely convenient means of connecting switches and other equipment into various arrangements.
  9. 9. THERE ARE TWO TYPES OF BUS :- 1.Main bus 2. Transfer bus
  10. 10. A switch is used in an electric circuit as a device for making or breaking the electric circuit in a convenient way
  11. 11. The control room is nerve center of a power station . The various controls performed from here are voltage adjustment, load control, emergency tripping of turbines etc.
  12. 12.  A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors-the transformer's coils.  Types:- 1. STEP-UP 2. STEP-DOWN
  13. 13. A transformer is a static device which transfers a . c. electrical power from one circuit to the other at the same frequency but the voltage level is changed
  14. 14. Power Line Carrier Communication, is an approach to utilize the existing power lines for the transmission of information.
  15. 15. The communication device used for the communication over the power lines is a MODEM, commonly known as Power Line MODEM (PLM). It works as both transmitter and receiver, i.e., it transmits and receives data over the power lines
  16. 16. It collects three primary types of data . 1.the status of process devices (digital inputs) 2. measures process variables (analog inputs) 3.accumulators (pulse inputs).
  17. 17. RTU database can be downloaded on operator request, from a PC using the SIM900 software. The software package delivered with S900 RTU allows to handle both digital and analog inputs/outputs
