Categories Related to DC Detectors
A DC voltage tester is a type of detector that is used to measure the voltage of a DC circuit.
By placing the DC voltage tester in contact with the part to be tested, it is possible to determine whether electricity is flowing through the part.
Generally, AC voltage is used in most circuits where electricity flows, and voltage testers are generally used exclusively for AC voltage. However, there are some cases where DC circuits are used, such as in train lines and electrical cables. It is necessary to check if DC voltage testers are used in such circuits, as the use of an inappropriate one may result in electric shock.
DC voltage testers are used in places where DC circuits are used and voltage is flowing. Common places include train lines and power plant cables.
When performing electrical work, we use an electric meter to confirm that there is no electricity before starting work. The places where electric inspectors are used are dangerous because electric current is flowing through them and touching them with bare hands may cause an electric shock. It is important to wear protective equipment when a high-voltage current is present.
DC voltage testers, like normal detectors, check to see if electricity is flowing at the point where the detector comes into contact with it.
Normally, when electricity is flowing through a wire, the electric field around the wire is variable. Therefore, when a detector is brought into proximity, it detects the changes in the electric field and emits a sound to indicate that electricity is present.
The type of detector used depends on whether DC or AC circuits are being used. If it is necessary to check whether electricity is present on either circuit, use a DC detector that can measure both voltages.
The type of detector should also depend on the magnitude of the voltage. Note that a detector that can measure high-voltage current may not react if it is used in the low-voltage part of the circuit.
