How to choose frequency conversion series resonance?       Nowadays, a lot of power industry related manufacturers will use series resonance tester, so we must compare and inspect the market of series resonance sales. Here, Zhizhuo measurement and control recommends you to choose famous large factories, so that they…

I. selection of high voltage circuit breaker - type and type       The type and type of high-voltage circuit breaker shall be selected according to the installation location, environment and service conditions of the circuit breaker. Vacuum circuit breaker has been widely used in 35kV and below power…

1. Inspection of iron core and clamp       The core of the transformer shall have sufficient mechanical strength. The mechanical strength of the iron core is guaranteed by the strength of all clamping parts on the iron core and their connecting parts. When the winding generates electric power,…

Substation   Power is transmitted through a power transformer. In the power system, the process of transforming the voltage from low level to high level (step-up) or from high level to low level (step-down) through certain equipment. Generally, the rated voltage of generator in power system is below (15-20) kV.…

Wuhan Zhizhuo measurement and Control Technology Co., Ltd. solves the problem that the test results of transformer tester cannot be saved   Problem Description: The analyzer startup process is normal, the test process is normal, and the test results are normal, but the test results cannot be saved, nor can…

In the ordinary work, the power workers often need to test the zero value of the insulator to test the voltage distribution value of the insulator string, so they need to use the insulator zero value tester. In the process of testing, the equipment has certain standards for the test…

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…
