KDS-3000Network PhaserIt is mainly used for phase sequence identification and labeling of transmission and distribution lines.
Its working principle is that the phased base station collects the phase signal of a certain area's line at regular intervals as a standard signal and uploads it to the main station server. During measurement, the sensor collects the signal of the measured line and sends it to the handheld device. The handheld device applies to the server for the data of the phased base station at the same time. By comparing the two phase data, the true phase of the measured line can be calculated.
The entire equipment mainly consists of a main station server, a phased base station, a handheld device, sensors, and accessories.

lPurpose: To identify the phase sequence of power transmission and distribution lines.
lIntegrate four functions: network phase determination, network free phase determination, remote core phase determination, and local core phase determination.
lA set of base stations can match an unlimited number of handheld devices to work simultaneously.
lThe system can perform phase detection in places without GPS or Beidou satellite positioning system and mobile network.
lThe phased base station adopts a high protection aluminum box, which is waterproof and dustproof, and can be used outdoors.
lThe phased base station can automatically sleep according to the system's working status to save network traffic.
lThe phased base station adopts the full network standard.
lThe handheld device comes with vector graphics and large font display, making it convenient and intuitive.
lThe handheld device displays detailed information, making it convenient for professionals to make data judgments.
lThe handheld device has an automatic shutdown function, which will automatically shut down after a certain period of inactivity.
