1, Applicable scope:
The leakage trace tester is a device that applies a certain voltage
between platinum electrodes of a specified size (2mm x 5mm) on the
surface of solid insulation materials, and drops a specified volume
of contaminated liquid (0.1% NH 4 CL) at a fixed height (35mm) for
30 seconds to evaluate the tolerance of the surface of solid
insulation materials under the combined action of electric field
and contaminated medium, and to determine its relative tracking
index (CTI) and resistance to tracking index (PTI).
Suitable for research, production, and quality inspection
departments of lighting equipment, low-voltage appliances,
household appliances, machine tool appliances, motors, electric
tools, electronic instruments, electrical instruments, and
information technology equipment, as well as insulation materials,
engineering plastics, electrical connectors, and accessory
industries.
