ZC-206A transformer winding deformation tester, based on the measurement of characteristic parameters of transformer internal windings, adopts the method of internal fault frequency response analysis (FRA), which is being developed and perfected by developed countries in the world, can accurately judge transformer internal faults.       After the design…

1. The operator shall read the instruction manual in advance, and master the functions, working methods, work preparation before test and correct test requirements of the instrument.   2. Before the test, disconnect both ends of the tested cable with armored grounding, and connect the remote end (end) of the…

1. Operators should read the instructions beforehand and master the functions, working methods, preparation before testing and correct testing requirements of the instrument.   2. Before the test, the armoured grounding at both ends of the cable under test is disconnected, and the distal end of the core wire is…

Strategy is a systematic understanding       Many friends may look at the strategy of "three types, two networks" and "comprehensive energy" in the clouds and mists of the national network. Many experts say that it is ubiquitous in the Federation of Things or integrated energy. More importantly, they…

I. Host preparation   1. Connection:   (1) Before testing, the cable under test should be cut off and its surrounding environment should be in a safe state.   (2) The generator is connected with the cable under test, and the red clamp is connected with one or several core…

Cable Identifier is a special instrument used to identify a particular cable from a bunch of cables in the erection, migration and maintenance of power cables and fault treatment. The cable identification instrument is composed of signal generator, clamp signal detector and indicator. The signal generator mainly produces special pulse…

ZCAR1600 universal relay tester's operating system supports on-site reinstallation, which is very helpful when the universal relay tester's operating system crashes or the device can't start up. All steps to reinstall the universal relay tester's operating system are following: Step1: Connect the  ZCAR1600 universal relay tester with keyboard and mouse…

CTA-1000 CT Analyzer compliance with standard <IEC60044> and <IEC61869>, and the standard basis for CT Analyzer measuring the excitation characteristics of iron cores by low frequency method is as follows: From IEC standard, CT testing can be done in conditions lower in frequency than the rated to avoid secondary windings…

       If the control box high voltage indicates that the meter is not normal (ie, the voltage data raised during the test cannot be detected). Preliminary inspection of the appearance, the secondary output of the auto-regulator is normal, the voltmeter is not abnormal, and the line connection is…
