Non-contact AC Voltage Sensor

Non-contact AC Voltage Sensor

By unique technology of Non-contact AC voltage sensor measurement stability made it possible.

Features

Features

When performing the measurement the AC voltage conventional multi-meter testers the tip portion of the probe indirectly attach to the portion of the wire.
This non-contact AC voltage sensor is in contact with conductor’s wire by measuring the AC voltage from the outside of the cable sheath without direct contact. The sensor can also measure any types of wire.

This voltage sensor, created by the technology of our own regardless of the thickness, types of wire, and the error of measurement is lesser and it enables stable measurement.
Since it is indirect contact with the conductor expose portion it measures from the outside of the wire coating. It can also prevent further accidents such as electric shock or short circuit.
It assures safety of workers and avoid possible risk of work accidents. Moreover, without having to power outages and equipment devices even hot line state, it is possible to install without difficulty affecting the plant in service and the sensor.

In addition, not only the voltage value it measures it also monitors the status of the voltage phase applied to the wire as a waveform data AC voltage. The non-contact sensor connect with the communication device of a wireless or wired, event detection and analysis of the waveform-based, multi-point monitoring can be observed.

For the non-contact sensor

Non-contact sensor that can be used for various purposes

1.The voltage monitoring in high-voltage distribution system

By adding to the large centralized power until now, such as nuclear power and thermal power generation, flows power by solar power and wind power are greatly influenced by unstable weather conditions. Non-contact sensor able to control the power to change from time to time keeping the supply-demand balance without difficulty.
In addition, the possibility that the voltage at the distribution line end is raised by reverse power flow from the solar power to be installed in the home, harmful interference to electrical equipment will be higher.
Therefore, needs for AC voltage measurement of high pressure increases for future use will be considered. At present, it has been measured at a lower voltage by pushing content intervening transformer. But by using a non-contact voltage sensor it is possible to directly measure the voltage and monitors base waveform event detection and analysis of such unbalanced-harmonic voltage.
These data will be part of the important data in the smart grid in collaboration with cloud computing technology and the evolution of sensor networks in the future. It will benefits in the future analyzing and controlling big data.

2.Use in electrical measuring instrument, such as a digital power meter and phase frequency
   meter

By utilizing the non-contact sensor and sensing the voltage, phase, and frequency, not only the AC voltmeter, and phase frequency meter and a digital power meter, it becomes possible to measure without contact.
It is safe to use in instruments particularly using in the field.

3.Take advantage of as zero-phase voltage detector

To detect or disconnect state of the balance voltage applied to the wires of the three-phase. When detecting the voltage of the zero-phase conventionally, it uses a transformer and voltage capacitor below. This non-contact sensor can also be used in the wire running on the existing it can detect the voltage of zero-phase without shutting off.
