Touch screen control - high voltage leakage trace tester

(NLD-AI type)

Meet the standards:

GB/T653-2003 and IEC60581:1984

Test Method for Evaluating the Resistance to Tracking and Corrosion of Electrical Insulation Materials Used under Harsh Environmental Conditions

Product Overview:

The high-voltage trace tester is suitable for testing the resistance to trace and corrosion of electrical and electronic products, household appliances, and their materials. It simulates the use of liquid pollutants and inclined samples at power frequency (48Hz-62Hz) to evaluate the resistance to trace and corrosion of electrical insulation materials used in harsh environmental conditions through measurement of resistance to trace and corrosion.

Product Features:

1. This instrument supports simultaneous testing of 5 samples, each with an independent control system for control

2. The core control system of this instrument is controlled by Siemens PLC, which collects voltage and current through photoelectric isolation, effectively solving the problem of anti-interference and maintaining stable data acquisition

3. The display part of this instrument is a 9-inch touch screen, which is easy to operate and has intuitive data display. It can display the leakage current of each sample in real time

4. The leakage current value can be freely set. When the current in the experiment exceeds the set current value, an alarm can be triggered and the high-voltage power supply can be cut off, without affecting other samples to continue the experiment

5. The droplet flow rate can be freely set according to actual needs

6. Adjust the test voltage clockwise using the manual knob.

7. Can manually and freely set the test time

8. This instrument has exhaust and lighting functions
