Load-shedding

Load-shedding
In an electric network, load-shedding consists in limiting the power installed. The device used to provide this function is called a load-shedding device.

The load-shedding device comes into play if the total power consumed exceeds the total value of the power contracted.
It prevents fuses or electric meters from breaking the circuit in the event that too much power is drawn and it maintains the comfort level.

Its principle: non-priority circuits are cut off during the peaks of power consumption.

The load-shedding device enables you to use all your electrical appliances (heating, refrigerator, oven, etc.) while keeping within the minimum power of the electric meter.
ATLANTIC’s load-shedding device has two elements:

- The toroid (accessory delivered with the load-shedding device), that measures the current on the power line at the input of the installation. It sends the information to the load-shedding device.
- The load-shedding device, featuring a current adjustment knob.



TECHNICAL CHARACTERISTICS


  • Cyclic load-shedding device on 3 non-priority outputs

  • Use of the pilot wires of heating appliances

  • 1 output for controlling an electric water heater (necessity of an additional clock – not supplied)

  • Ratings of 15 to 90 in steps of 5 ª

  • Load-shedding device operation display LEDs
 
  • Power supply: 230 V, 50 Hz

  • Maximum rated power: 3 W

  • Current measured by a C.T. (external current transformer)

  • Single phase

The 3 non-priority outputs enable the load-shedding device to cut off the heating in a cyclic manner for a few minutes to give priority to household appliances or any other items of electrical equipment.

The cyclic operation enables the load-shedding time to spread over the 3 non-priority pilot wire outputs.
