The circuit for direct loading is shown in the figure below. Phantom load blocker Abstract The present invention relates to an electrical energy saving device more specifically it relates to an energy saving circuit which automatically cuts the power. While the energy used for keeping these appliances plugged in is minimal, it can add up over time and end up costing you money on your electric bill. The power consumption of the load by direct and indirect phantom is explained below. ‘Phantom load’ refers to the electricity consumed by electronics that are plugged in and not currently in use. The resistance of the pressure coil and the current coil is 4400Ω and 0.1Ω respectively. Example of Phantom LoadingĬonsider the DC energy meter having rating voltage 220V and current 9 Ampere. The total current supplied for the phantom loading is the sum of the pressure coil current which is supplied at normal voltage and the current of the current coil supply at low voltages. The pressure and current coil circuit have low impedance (less obstruction of movement of the electron) because of which highly rated current is passed through it. The pressure coil is energised from the small supply voltage, and the current energises the current coil at very small voltages. Operating Temperature : 10.+60 Celsius degrees Supply Voltage : 85.264VAC / 45.65Hz / 25VA Weight : 1.2kg Description Current source (phantom load) type Calmet CC11 together with electricity meter tester (type Caltest, Calport and other) is dedicated to test all types of single and three phase electricity meters. In phantom loading, the pressure coil and the current coil are separately excited by the supply source. The phantom loading consumes very less power as compared to real loading, and because of this reason, it is used for testing the meter. The actual loading arrangement will waste a lot of power.

The phantom loading is used for examining the current rating ability of the energy meter.
