NEW FUZRR ES3080 Three-channel DC Resistance Tester
Ⅰ. Characteristic
ES3080 DC resistance tester, also known as transformer DC resistance tester, etc., is mainly to check whether the connection between windings, between windings and leads or whether the mechanical properties are good, whether the resistance between each phase winding is balanced, etc., to ensure the safety of the transformer. run.
Transformer DC resistance tester is a new type of instrument used to measure the DC resistance of large-capacity transformers. It is designed as a high precision current stabilized power supply and test assembly. During the testing process, it is controlled by computer and automatically completes steady-state judgment, data acquisition, data processing and resistance measurement. Numerical display and printing. The instrument can be used for longitudinal testing of on-load voltage regulators with one-time power supplies, thus completely saving testing time. It also has a temperature rise test function for transformer manufacturers. It has the characteristics of simple operation, high precision, anti-interference, etc. It can quickly and accurately measure various types of transformers. The magnetization method is to charge the low winding by generating a magnetic field for the high winding output current. With the help of the excitation ampere-turns of the high-voltage winding, the winding inductance is greatly reduced by passing a small current, so as to shorten the measurement time and achieve the purpose of fast measurement. It should be noted that when the DC resistance of the low-voltage winding is measured by the magnetic-assist method, the current directions of the high-voltage and low-voltage windings on the same core column must be the same, so that the magnetic-assisting effect can be achieved.
ES3080 DC resistance tester is composed of host, test line, ground rod, etc. It has the functions of reading, viewing, saving, and printing historical data.
