Temperature rise testing is a key step in evaluating the operational reliability of new grid components like transformers, switchgear, cables, generator, etc. Work together with high current transformers, GTM-III is used to measure switchgear each point temperature data up to 56.
GTM-III is a simple temperature data logger, which can work with any high current transformers. They are separately other. With a mini printer, you can print the data after the test.
Temperature benchmark preset in advance.
Advanced filtering algorithm to filter off various interferences, such as power &double frequency, transient;
Support thermocouple calibrating compared with the standard thermocouple.
All IEC thermocouples are supported; all temperature voltage tables are preloaded already.
Controlled by micro computer and printed the temperature rise value of each testing point and the three environment temperature.
