Power workers in the work, often need to contact a called capacitance inductance tester instrument, the device is also very widely used in the power industry, but many people do not know the equipment is mainly used for what, this article will give you a simple introduction to this.
With the transformation of urban agricultural power grid, capacitor compensation devices have been developed and newly developed products have been put into use. However, the accident rate of capacitors has greatly increased, especially the explosion and fire accidents that have not been seen for many years, and serious personal injury accidents have occurred. Expert working group of reactive power compensation device organized experts to analyze the accident carefully. After study, it was found that the accident rate rose in addition to the decline of product quality of manufacturers, another very important reason is: the technical management of reactive power compensation and the handover of old and new operators, no operation anti-accident measures.
In view of the present demand for capacitor test of the electric power industry, our company seriously capacitance inductance test device was developed, considering the current market the advantages and disadvantages of various sealed, capacitance measuring instrument, the equipment is big characteristic is "no break line, anti-jamming, high precision and not easy to damage", greatly improving the work efficiency and ensure the test operation.
In the measurement of capacitance voltage measurement of capacitor branch, used for sampling respectively connected to the amplifier circuit sampling circuit of the output current sampling circuit, output from the voltage amplification circuit of voltage signal and the phase current from the amplifying circuit output current signal output phase difference signals, voltage and current signal by A/d converter, The CPU calculates the input value of the measured capacitance. Because the current sampling unit is used to move, so that the connecting line can be measured directly without removing capacitance values. The combined measurement range is automatically selected to provide excellent stability, repeatability, accuracy and reliability due to manual operation avoiding errors.
Inductance capacitance tester is mainly for substation field measurement the value of a single capacitor in parallel capacitor group problems specially developed, furthermore, its current measurement unit can also double as CVT, lightning arrester, such as measurement of electrical equipment, has used a multipotent effect, therefore is popular among the electricity workers.
