What is the current shooting?
The reduction of current is detection and conversion of electric current into an observable form. Electric current is the speed of electric charge flow. The higher the current in fixed resistance, the higher the voltage across this resistance. The current flow can be measured using current sensors, while current sensing resistors convert the current to voltage. If the electrical voltage has no current flow with it, it is similar to a closed faucet that stops a high -pressure water source. The equivalent current sensing device is a flow that uses a rotating shoulder blade that rotates faster when the flow is high. The blade speed is proportional to the flow. This is compared to the transformer principle, anywhere on the primary winding of the transformer is induced at secondary winding. The stronger the primary current, the higher the secondary current.
Clamp on current measuring works on the principle of magnetic induction. When the magnetic self isDro clasped around the wire bearing current, the secondary current is induced, which is the function of the primary current. The pocket terminals usually have voltmeters on the same device. The ability to measure the current without interrupting the test circuit and to measure the voltage makes this test device very useful for preventive and corrective maintenance.
Energy control systems use current sensing to detect a failure in the circuit. For example, if the three phase lines must be a balanced load, the neutral conductor will usually cancel the current through them. Reducing the neutral wire current is the basis for the defective condition, which makes the correct answer.
Current sensory amplifiers have many uses in electronics, automation and instrumentation. The current sensor resistor is usually part of the series and in the series with a bus bar that provides power from the rectifier on the load side. Sensive voltage amplifiers can detect a sample that is proportional to current current. If there is a current of 100 amps (a) across fromThe pure, which is 0.001 Ohm, is the observed voltage of 0.1 V, which corresponds to 100 and the current load. The resistor mentioned together with the voltage sensing amplifier is configured as a current amplifier.
