Leakage Tracing Test Apparatus

Leakage Tracing Test Apparatus for Manufacturers and Test Labs

Purpose-built systems to evaluate surface tracking resistance and leakage paths on polymers and other electrical insulating materials. These testers support repeatable CTI/PTI and erosion assessments. They combine stable high‑voltage control, precise electrolyte dosing, rigid sample fixtures, and digital data capture so you can benchmark materials and qualify products with confidence.

Core Advantages for Reliable Tracking Assessment

With 17+ years of R&D and ISO 9001–certified manufacturing, we deliver stable HV performance, finely metered droplet flow, and CNC‑machined fixtures for consistent alignment. In‑house calibration and deep knowledge of international methods support accurate, traceable results. OEM/ODM customization, installation assistance, and lifetime support—backed by global supply—help align your setup with lab protocols and production needs.

Standards and Methods Supported

Systems perform Comparative Tracking Index (CTI) and Proof Tracking Index (PTI) per IEC 60112, ASTM D3638, and GB/T 4207. Tracking and erosion tests per IEC 60587 are also supported. Electrode geometry, electrolyte concentration and rate, voltage steps, and pass/fail criteria can be configured to match material class and method.

Features and Specifications

High‑Voltage Control and Safety

Closed‑loop voltage regulation maintains stable arc conditions. Interlocked doors, HV cut‑offs, flame‑resistant viewing windows, and integrated exhaust help protect operators.

Electrolyte Delivery and Electrodes

A calibrated drop system dispenses electrolyte at set intervals for repeatability across operators. Platinum or stainless‑steel electrodes meet specified geometry and force.

Sample Holding and Thermal Management

Rigid, micrometric fixtures align specimens to the test axes for consistent contact. Optional temperature monitoring tracks heat effects during sustained tracking or erosion.

Data Capture and Traceability

Digital logging records voltage, leakage current, arc events, and time‑to‑failure. Automated reports use method templates with operator IDs and lot references.

Typical Specifications (configurable)

• Voltage range: 100–600 V or 100–1000 V, depending on method


• Electrode angle/force: per IEC 60112 / IEC 60587


• Electrolyte dosing: 44 ± 4 drops/min adjustable; reservoir with level sensing


• Safety: HV interlock, emergency stop, exhaust, arc shield, overcurrent protection

Product Variants and Configuration

CTI/PTI Test Systems (IEC 60112 / ASTM D3638)

Designed for comparative and proof index testing with standardized electrode force, controlled voltage steps, and automated failure detection to speed batch qualification.

Tracking/Erosion Chamber (IEC 60587)

Rugged chamber with durable fixtures and electrolyte manifolds for surface erosion assessment under severe conditions.

Custom Options

Camera‑based arc visualization, extended voltage ranges, alternative electrode materials, and integrated humidity conditioning can be tailored to your workflow.

Applications and Use Cases

Assess plastics, rubbers, and composites used in connectors, switchgear, consumer electronics, household appliances, automotive/EV components, and power distribution. Where surface leakage and tracking resistance influence safety and performance, these systems provide comparable, repeatable results.

Workflow and Installation

On‑screen prompts guide specimen preparation and conditioning, electrode setup, electrolyte calibration, and stepwise voltage application with built‑in safety checks. Bench‑top units fit standard lab benches with an exhaust connection. Chamber units require dedicated ventilation and HV safety clearance.

Quality Assurance, Calibration, and Support

Each unit is factory‑calibrated with traceable certificates. Our team provides method setup, operator training, and periodic calibration kits. Remote diagnostics and on‑site service help maintain uptime over the product lifecycle.

Selection FAQ

What is the difference between CTI and PTI?

CTI determines the maximum voltage at which a material resists tracking. PTI verifies performance at a specified proof voltage.

Which utilities are required?

Standard AC power, electrolyte supply, and exhaust/ventilation. Chamber systems need additional clearance for HV safety.

How often should the system be calibrated?

Follow your quality plan; many labs verify droplet rate and voltage annually or after major maintenance.

Category Position and Related Equipment

This category focuses on surface tracking and leakage path evaluation. It complements flame tests such as UL 94 and ignition source methods (Glow Wire, Needle Flame), as well as temperature/humidity chambers for pre‑ or post‑conditioning.
