2. Current clamp - Wikipedia

   en.wikipedia.org/wiki/Current_clamp

   An electrical meter with integral AC current clamp is known as a clamp meter, clamp-on ammeter, tong tester, or colloquially as an amp clamp. A clamp meter measures the vector sum of the currents flowing in all the conductors passing through the probe, which depends on the phase relationship of the currents. Only one conductor is normally ...

3. Ammeter - Wikipedia

   en.wikipedia.org/wiki/Ammeter

   An ammeter (abbreviation of ampere meter) is an instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. For direct measurement, the ammeter is connected in series with the circuit in which the current is to be measured.

4. Shunt (electrical) - Wikipedia

   en.wikipedia.org/wiki/Shunt_(electrical)

   Some alternatives to shunts can provide isolation from the high voltage by not directly connecting the meter to the high voltage circuit. Examples of devices that can provide this isolation are Hall effect current sensors and current transformers (see clamp meters). Current shunts are considered more accurate and cheaper than Hall effect devices.

5. Clamper (electronics) - Wikipedia

   en.wikipedia.org/wiki/Clamper_(electronics)

   A negative clamp is the opposite of this—this clamp outputs a purely negative waveform from an input signal. A bias voltage between the diode and ground offsets the output voltage by that amount. For example, an input signal of peak value 5 V (V INpeak = 5 V) is applied to a positive clamp with a bias of 3 V (V BIAS = 3 V), the peak output ...

6. Synchronization (alternating current) - Wikipedia

   en.wikipedia.org/wiki/Synchronization...

   At that instant, the circuit breaker connecting the generator to the system may be closed and the generator will then stay in synchronism with the system. [ 3 ] An alternative technique used a similar scheme to the above except that the connections of two of the lamps were swapped either at the generator terminals or the system terminals.
