What is electrical load?

Current flows through a circuit only when it is closed. So, to get a steady flow of current loads are needed to be connected at the terminals of the circuit. Without the load the circuit is said to be open circuited.

If the circuit is completed without connecting the load the circuit is termed to be at short circuited condition the current flow is very huge at the point which can damage the circuit. Load is nothing but impedance. There are several types of loads present depending on their nature which are listed below.

According to load nature

  •     Resistive electrical loads
  •     Capacitive electrical loads
  •     Inductive electrical loads
  •     Combination electrical loads

According to load function

  •     Lightning load
  •     Small appliances load
  •     Power loads

According to load consumer category

  •     Residential electrical loads
  •     Commercial electrical loads
  •     Industrial electrical load
  •     Traction loads

According to load grouping

  •     Industrial loads
  •     Load center

According to load planning

  •     Existing electrical loads
  •     Future electrical loads
  •     New electrical loads

According to load operation time

  •     Continuous electrical loads
  •     Non- continuous electrical loads
  •     Duty intermittent electrical loads
  •     Duty periodic electrical loads
  •     Duty short time electrical loads

According to load/phase distribution

  •     Balanced electrical loads
  •     Non-balanced electrical loads
  •     Neutral loads
  •     Line to neutral load

According to number of electrical loads phases

  •     Single phase electrical loads
  •     Three phase electrical loads

According to electrical loads usage method

  •     Fixed place loads
  •     Portable loads

According to method of load reduction /control

  •     Dimmed electrical load
  •     Shed electrical load
  •     Shifted electrical load.
