Product Details

Currently, most phase detectors on the domestic and international markets are short-range, high-energy-consuming, and single-function devices. With the continuous development of power grids, phase detection tasks are no longer just simple phase checks; high-voltage phase sequence, phase relationships, relative phasing, and live indication are all included in phase detection tasks. Therefore, choosing a multifunctional, high-performance, low-energy wireless voice high-voltage phase detector is crucial.

The 35KV High Voltage Wireless Phase Detector is another high-performance wireless phase detector upgraded by our company based on previous products. The entire unit is powered by a high-performance imported lithium battery, and an external battery design is also added, allowing users to use the internal lithium battery or external ordinary batteries in urgent situations, greatly improving on-site practicality. Its intuitive three-phase phasor diagram and real-person voice function provide power engineers with direct and reliable judgment basis.

The main advantage of the 35KV High Voltage Wireless Phase Detector is that it eliminates the need for leads connecting the two power grids (power sources) at both ends (distance up to 200m), can pass through walls or partitions (panels), and is not limited by any terrain or facility structure, improving safety and making operation extremely convenient, requiring only one operator and one supervisor..

This product complies with national standards GB13398-92, GB311.1-311.6-8, 3DL408-91, and the newly issued power industry standard "General Technical Conditions for Portable Phase Detectors for Live Working 1kV~110kV DL/T971-2005".

• 
  Dual power supply design. The transmitter has a built-in large-capacity maintenance-free lithium battery, and can also be powered by AA batteries. The internal lithium battery serves as a backup power source. In urgent situations when the lithium battery is not charged, ordinary AA batteries can be used, completely solving the problem of charging the lithium battery in emergencies.


• 
  Accurate test results. Multiple software and hardware filtering eliminates false test result reports.


• 
  Uses a 3.5-inch true color LCD screen to clearly display phasor diagrams and test results.


• 
  Long test distance, up to 200 meters line-of-sight, and can be used through walls.


• 
  Multifunctional design. Includes phase detection, phase sequence detection, and live indication functions.


• 
  Real-person female voice announces test results, making testing more convenient.


• 
  Telescopic insulating rod, easy to carry and use, with insulation performance meeting the withstand voltage test requirements for electrical insulating tools.

• 
  Detectable voltage range: 0.4 ~ 500kV (standard configuration is 6 ~ 110kV);


• 
  Wireless transmission distance: ≥ 200 meters line-of-sight (over 300 meters requires customization);


• 
  Test accuracy: 0.1°;


• 
  Same-phase definition: strictly designed according to regulations, phase angle ≤15° is same phase, phase angle ≥15° is different phase (the judgment range can also be defined according to user requirements);


• 
  Operating frequency: 45~60Hz, suitable for phase detection on 60Hz power grids abroad;

• 
  The transmitter (two units) body is made of high-voltage-resistant nylon material, insulation level: 80kV/cm;


• 
  The insulating telescopic rod (material) uses moisture-proof insulating tubes produced by military enterprises, complying with IEC/1C78 standards, featuring moisture resistance, high voltage resistance, impact resistance, and bending resistance. The material properties are shown in Tables 1 and 2, and Table 3 lists the comprehensive parameters of this phase detector.
