A current measurement unit (112) measures the input current (Ic) in the charger (114).

The current sensing circuit (32) measured the low side current.

The first current sensor measures a current through the single-phase line break protector.

The power measuring unit measures the power supplied from a power supply or the amount of power per unit time.

The current measuring mode includes current amplifier (26) controlling a flow of current through the electric coil (21) and a current sensor (27) facilitating a measurement of the flow of current through the electric coil (21).

The current measuring unit measures the current supplied to the induction motor due to the supplied voltage.

The current supplied to the main bus is measured.

A measuring circuit applies a DC current to a device under test (DUT) and measures the DC current flowing in the DUT.

A current detection unit measures the current flowing through the rechargeable batteries.

A beam current measurement circuit (BMC) measures the total current (IT) which is the sum of the total current in the first electrode (ICA) and the compensation current (ICO).

A second current sensor (34) measures return current from the ion collector (26).

The current sensor measures the current supplied from the main unit to the breaker and outputs a current detection signal in accordance with the measured current.

A first beam measurement mechanism (124) measures beam current of the positive portion to obtain a positive angle beam current measurement.

A second beam measurement mechanism (126) measures beam current of the negative portion to obtain a negative angle beam current measurement .

A current transformer (111p) measures current at the power generation grid side of the connection point.
