What is NCV non-contact voltage test pen?
Cable breakage can be said to be the daily cable integrated wiring installation and maintenance work in the most common - a kind of cable failure -. However, the actual project maintenance and repair, for many maintenance personnel, encountered in the middle of the wire and cable breakage is a very headache. When the internal medium of the cable breakage fault, because of its external insulation cover, we can not see the exact location of the strong and weak state are so, maintenance personnel is difficult to safely and efficiently determine the location of the breakpoint.
With the progress of science and technology, there are a variety of efficient detection tools, this problem has been effectively solved. Among the many testing tools, the compact and portable NCV non-contact power measuring pen is a very high frequency of application of a testing instrument.
NCV non-contact stylus
"NCV" is the abbreviation of NON CONTACT VOLTAGE, meaning "Non-Contact Voltage Detection", used to determine whether the object under test is charged, i.e., does not break the skin of the wire, without contacting the electrode in the case of detecting whether there is electricity in the wire (FireWire). NCV Non-Contact Voltage Detector uses electromagnetic field induction detection technology to detect whether an object is charged or not. It can be used to search for buried live wires in walls, or to find buried broken wires, etc. It is suitable for use with higher AC voltages. It only determines whether there is voltage present or not, and cannot measure the level of a specific voltage.
Typically, the NCV non-contact stylus can also be used to distinguish between zero and fire wires in an outlet, with an audible and visual alarm when the fire wire is detected, and no audible or visual alarm when the zero wire is detected.
High and low voltage stylus belongs to the maintenance and inspection tools. In many pens, NCV non-contact pen is widely used because of its high safety and efficient measurement. This AC-15EX/AC-15EXS from Huashengchang is not only safe to use and compact, but also has an explosion-proof function, which can meet the high demand of people who want to measure safely and normally even in potentially explosive environments.
