When choosing to purchase transformer winding deformation tester, power enterprises should make accurate judgment and select the equipment produced by those powerful companies, so that the accuracy and accuracy can be guaranteed, and the transformer can be found in time in case of failure, so as to ensure the safety…

The use of the instrument transformer tester must comply with the technical requirements of the existing national standards for electrical safety and test project process. Reading this manual does not replace the requirements of the relevant national standards for electrical test projects. When using the instrument transformer tester in high-voltage…

Voltage transformer is similar to transformer, the transformation of voltage on power system line needs to use transformer. The purpose of transformer transformation voltage is to transmit electric energy. Unlike transformer, transformer transformation voltage is mainly used to supply power for relay protection device and measuring instrument. The voltage, electric…

The problems that electric power workers need to pay attention to when using the microprocessor relay protection tester for AC test are summarized as follows:   1. In general detection of relay protectors, one of the steps is to set the "switch positioning confirmation time". Here we need to pay…

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…
