Transformer winding deformation test instrument based on the measurement of the characteristic parameters of transformer internal winding the internal fault frequency response analysis (FRA) method which is being developed in developed countries is adopted to make an accurate judgment of transformer internal fault.
After the design and manufacture of transformer is completed the line coil and internal structure are determined. Therefore for a multi-winding transformer line coil if the voltage grade is the same and the winding method is the same the corresponding parameters (Ci Li) of each line coil should be determined. Therefore the frequency domain characteristic response of each line coil is determined accordingly and the frequency spectrum of the corresponding three-phase line coil is comparable to some extent.
The distribution parameters of transformer windings will change when short-circuit between turns and phases occurs in the test process or collision occurs in the transportation process resulting in the relative displacement of the line coil and the deformation of the line coil caused by electromagnetic tension in the short-circuit and fault state during the operation process. Then it influences and changes the original frequency domain characteristics of the transformer that is amplitude change of frequency response and resonance frequency offset. The transformer winding test instrument developed according to the response analysis method is such a novel non-destructive testing equipment for transformer internal faults. It is suitable for the internal structure fault detection of 63kV ~ 500kV power transformer.

Transformer winding deformation test instrument based on the measurement of the characteristic parameters of transformer internal winding the internal fault frequency response analysis (FRA) method which is being developed in developed countries is adopted to make an accurate judgment of transformer internal fault.
After the design and manufacture of transformer is completed the line coil and internal structure are determined. Therefore for a multi-winding transformer line coil if the voltage grade is the same and the winding method is the same the corresponding parameters (Ci Li) of each line coil should be determined. Therefore the frequency domain characteristic response of each line coil is determined accordingly and the frequency spectrum of the corresponding three-phase line coil is comparable to some extent.
The distribution parameters of transformer windings will change when short-circuit between turns and phases occurs in the test process or collision occurs in the transportation process resulting in the relative displacement of the line coil and the deformation of the line coil caused by electromagnetic tension in the short-circuit and fault state during the operation process. Then it influences and changes the original frequency domain characteristics of the transformer that is amplitude change of frequency response and resonance frequency offset. The transformer winding test instrument developed according to the response analysis method is such a novel non-destructive testing equipment for transformer internal faults. It is suitable for the internal structure fault detection of 63kV ~ 500kV power transformer.

Product Introduction
With the development of China's electric power industry the capacitor compensation device has been unprecedentedly developed but with it the capacitor accident rate has risen sharply and there have been serious group injury accidents. In order to prevent the occurrence of parallel capacitor accidents and ensure the safe and reliable operation of the power grid State Grid Corporation has formulated the "Measures for Preventing High Voltage Shunt Capacitor Accidents". It is clearly stated that "the measurement of the capacitance of a single capacitor of a capacitor bank should be carried out on a regular basis. It is recommended to use a measurement method that does not remove the connecting wire to avoid the failure of the casing to leak due to the force of the casing caused by the disassembly and assembly of the connecting wire".
Automatic capacitance and inductance tester is designed for the problems in the measurement of high voltage shunt capacitor banks in substation sites and refers to GB3983.2-1989 "High Voltage Shunt Capacitors" DL/T840-2003 "Technical Conditions for Use of High Voltage Shunt Capacitors" and JB5346 -1998 "Series reactor" and other national standards and specially developed mainly to measure the high voltage shunt capacitor bank and reactor of reactive power compensation device.
Automatic capacitance and inductance tester adopts a new generation of high-speed hybrid microprocessor which is highly integrated synchronously collects the voltage signal and current signal of the test object and automatically calculates the capacitance value inductance value and reactive power value. On-site measurement of capacitors eliminates the need to remove the connecting lines simplifying the test process effectively improving work efficiency and avoiding damage to power equipment. After the test the capacity of each phase capacitor and other parameters are automatically calculated and it is easy to discriminate the quality change of the capacitor and the connection conductor failure between devices. At the same time the automatic capacitance and inductance tester also features data storage and USB communication eliminating the need to copy data on-site and ensuring complete measurement data.

Power test procedures for a number of power equipment such as: cable motor generator transformer transformer high voltage switch lightning arrester and other requirements to do a series of insulation performance tests the first is to do insulation resistance test.
When testing the insulation resistance of large-capacity power equipment the insulation resistance value is related to the pressurizing time. The longer the pressurizing time is the higher the insulation resistance value is. This phenomenon is called insulation absorption phenomenon. In order to understand the insulation performance of the subject it is necessary to conduct the absorption ratio and polarization index test first so as to provide safety guarantee for the next leakage dielectric loss partial discharge and insulation performance test.

Dc systems in power plants and substations provide power supply for control protection signals and automatic devices. The safe and continuous operation of dc systems is of great importance to ensure power supply and distribution. As the dc system is not grounded by floating system if two-point grounding occurs it may cause the above devices to misoperate and refuse to operate thus causing a major accident. Therefore when one point grounding occurs the grounding point should be accurately and quickly detected while ensuring the normal power supply of the dc system to eliminate the grounding fault so as to avoid the possible harm of two points grounding.
DC system grounding fault tester is used to find the exact location of DC system grounding points of power plants and substations in the case of constant electricity. All kinds of grounding faults can be found out quickly with good accuracy.

Transformer oil acid tester is a fully automatic measuring instrument which adopts the extraction method to accurately detect the insulating oil acid value. This instrument can improve the working efficiency and test accuracy, and at the same time ensure the safety of the body by reducing the operator's contact with the samples and reagents.
The acid value is the trace value of potassium sulfate that neutralizes the petroleum acid in 1g of oil, which contains a certain amount of inorganic acid and inorganic acid. The acid value includes organic and inorganic acids contained in the oil. In most cases, oil does not contain mineral acids. Therefore, the oleic acid value actually represents the content of organic acids in the oil. The organic acid contained in the new oil is mainly cyclonic acid. In the oil and in the process of use, the acid value of the oil produced by oxidation is an indicator to measure the degree of refining of the new oil. Whether the oil is running is an important indicator of the continued use of oil quality equipment.
