1: Online Detection Without Power Cut, Maintenance Efficiency Increased by 80%

• Product Feature: Non-contact signal injection via coupling clamp, no need to disconnect low voltage live wire & neutral wire, no power-cut report coordination with users;
• Technical Support: Independent characteristic circulation isolated from power frequency loop, detection will not affect normal power consumption of residents and factories;
• Customer Benefit: Traditional segmented power-cut inspection takes average 120 mins for single leakage fault, this instrument locks fault point within 20 mins on average, 3-5 fault rush repairs can be finished per day, greatly improving operation & construction efficiency.
   

2: Triple Detection System, Full Coverage of All Working Conditions Without Blind Spots

• Product Feature: Flexible clamp for general leakage screening of transformer area + clamp slave unit for overhead main line inspection + handheld slave unit for hidden fault positioning, one set replaces 3 single-function testers;
• Technical Support: Flexible coil collects zero-sequence leakage current of four lines synchronously, two slave units conduct long & short distance induction separately, 4-channel signals match main unit uniformly with synchronous & error-free data;
• Customer Benefit: No need to purchase multiple testing instruments separately to reduce total procurement cost, compatible with all test scenarios including outdoor, indoor, high-altitude and underground cables.
   

3: Matched Intelligent Bluetooth Analysis APP, Fit for Digital Distribution Account Management

• Product Feature: Connect two slave units simultaneously via mobile Bluetooth, free switch of 4 channels, real-time current value display by A/B/C/N phase, auto generate test waveform curves; support grouped data storage, history record query and data filing;
• Technical Support: Real-time collection of characteristic current value, APP automatically compares current difference before and after fault, visually displays leakage attenuation curve;
• Customer Benefit: Meet digital operation filing requirements of State Grid transformer stations, completely replace paper records, fit for bidding of smart power grid and modern property maintenance projects.
   

4: Universal Battery Power Supply Scheme, No Endurance Shortage for Outdoor Work

• Product Feature: Main unit with large-capacity lithium battery for long endurance, two slave units and flexible clamp meter all adopt commercially available No.7 / 9V dry batteries;
• Technical Support: Split independent power supply design, ordinary dry batteries can be purchased locally for replacement when no charging condition outdoors, no special supporting chargers required;
• Customer Benefit: No need to carry multiple chargers for outdoor inspection, eliminate endurance worries for field rush repair, reduce after-sales consultation and complaints related to battery life.
   

5: Multiple Safety Protection Design, Comply with Power Operation Safety Standards

• Product Feature: Whole machine insulation fits AC600V low voltage operation, signal only transmitted through coupling clamp, direct connection of main unit to live lines is strictly prohibited; operation not recommended on rainy days, auto power-off under low voltage, sealed insulated equipment without exposed metal parts; matched IP67 waterproof & shockproof protective case;
• Technical Support: All equipment pass withstand voltage & insulation test before delivery, signal loop isolated from high voltage live loop to avoid electric shock risk; unauthorized disassembly will void official warranty;
• Customer Benefit: Meet mandatory safety assessment standards of power supply stations and power engineering, full safety instructions can be directly used for safety qualification response in bidding.

• Urban & Rural 0.4kV Low Voltage Distribution Transformer Area: General leakage inspection at transformer main grounding point and area branch box, rapidly locate leakage partition;
• Outdoor Overhead Power Lines: Inspection of leakage faults on high-altitude main lines, T-joint branch lines, road/tree crossing cables, solve frequent RCD tripping issues;
• Residential Incoming Distribution Lines: Detection of neutral/live wire earth leakage of community households, hidden earth faults of indoor concealed wires;
• Utility Pole Auxiliary Facilities: Detection of earth leakage caused by metal stay wires, pole grounding and damaged insulators;
• Industrial & Mining Plant Power Distribution: Inspection of workshop low voltage cables, equipment shell earth leakage and distribution cabinet zero-sequence leakage;
• Property Community Operation & Maintenance: Regular inspection of basement cables, wall-through pipelines and leakage caused by green trees touching wires;
• Power Engineering Rush Repair & Third-party Distribution Testing Institutions: Rapid survey of mass fault points, leakage testing for project acceptance;
• High & Low Voltage Complete Equipment Factory: Pre-inspection of hidden leakage hazards for complete distribution cabinets before delivery.
