  • • 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.
  • It is an automatically-operated electrical switch. It operates both on “ON LOAD” and “NO LOAD” conditions.
  • The protective relay ensures the safety of the circuit equipments from any damage which might otherwise cause by fault.
  • 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 .
  • Lightning arrestors directly connected at one end to the transmission system.
  • Bus-bars are merely convenient means of connecting switches and other equipment into various arrangements.
  • THERE ARE TWO TYPES OF BUS :- 1.Main bus 2. Transfer bus
  • A switch is used in an electric circuit as a device for making or breaking the electric circuit in a convenient way
  • 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.
  •  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
  • 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
  • Power Line Carrier Communication, is an approach to utilize the existing power lines for the transmission of information.
  • 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
  • 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).
  • 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
