🔬 On-Site PD Measurement

Enables accurate partial discharge detection (<5pc) in="" cable="" termination="" tests="" without="" fixed="" lab="" equipment.="">

⚡ Field Research Projects

Portable solution for university research teams conducting HV experiments in remote locations.

Design Features

• Advanced composite housing: Fiber-reinforced polymer for 50kV insulation in compact form

• Integrated cooling fins: Passive thermal management for 60-min full load operation

• Quick-connect terminals

• Corona-free design: Triple-shielded connections with silicone insulation

• Environmental protection: IP54 rating for dust/moisture resistance

Safety & Field Operation

1. Verify ground connection (

   <0.5ω) before="" energizing="">

2. Maintain minimum 0.5m clearance from grounded surfaces

3. Monitor surface temperature with IR thermometer (max 80°C)

4. Allow 30-minute cooldown between full-load tests

Safety Certification: Compliant with IEC 61010-1 safety requirements for portable HV equipment.

Maintenance Protocol

• Monthly visual inspection for casing integrity

• Quarterly resistance verification (±1% tolerance)

• Annual dielectric test: >1000MΩ @ 5kV DC

• Clean terminals with isopropyl alcohol after field use
