Product features and applications
Rich measurement functions
It can perform near-range phase verification of 5V~220kV AC transmission lines and secondary live indicators, and also supports three-phase line phase sequence detection, and has the function of live line detection.
High measurement accuracy
Phase difference error ≤ 5°, frequency accuracy ± 0.1 Hz, phase comparison results are judged according to national standard A level, and the data is accurate and reliable.
Convenient transmission and operation
Employing digital wireless transmission technology, the transmitter and receiver have a maximum line-of-sight range of approximately 100 meters. It features real-person voice prompts, a 3.2-inch color screen that intuitively displays information such as phase difference and vector diagrams, and simple operation with a long press to turn it on/off and a short press to switch functions.
Excellent safety performance
During high-voltage measurement, the leakage current is <10uA. The standard configuration includes a 3-meter insulating rod suitable for voltages ≤220kV. The insulating rod is high-voltage resistant and impact-resistant. The transmitter will sound an alarm when it comes into contact with a live line. The self-test line is connected in series with high resistance to ensure operational safety.
Good battery life and energy efficiency
Both the transmitter and the main unit have built-in rechargeable lithium batteries and come with a dedicated charger; the device automatically shuts down after 1 hour of continuous inactivity, with the transmitter consuming less than 0.1W and the receiver less than 0.3W, resulting in low energy consumption.
Strong environmental adaptability
It can work in environments with temperatures ranging from -35℃ to +45℃ and humidity ≤95% RH. The insulating rod is made of moisture-proof insulating tube material, making it suitable for various outdoor work scenarios.
Prodection details
High-voltage transmission line work
It is suitable for short-range phase verification of 5V～220kV AC high-voltage transmission lines, and meets the on-site testing requirements for grid connection and ring network phase verification.
High-voltage switchgear testing
It can perform low-voltage phase verification on the secondary live indicator of high-voltage switchgear, and assist in verifying the live status and phase of the switchgear.
Three-phase line phase sequence determination
It is applied to phase sequence detection of various three-phase power lines, and can quickly determine the forward, reverse or disordered state of the line.
Live-line testing of power lines
It can independently detect whether a power line is energized, providing a basic basis for judging the safety of energized power lines during on-site power operations.
Generator grid connection
Phase sequence and phase sequence test results can assist in the quasi-synchronous/self-synchronous grid connection operation of generators, ensuring grid connection phase and frequency matching.
Power equipment self-inspection and maintenance
The instrument can perform self-testing and can also be used in conjunction with the insulating rod withstand voltage test for routine maintenance and calibration of power testing equipment.
