High voltage insulation megohmmeter is composed of medium and large scale integrated circuits. This meter has large output power high short-circuit current value and large output voltage grades (there are four voltage grades). The working principle is as follows: the DC high voltage generated by the battery inside the machine as power supply and converted by DC/DC reaches the L pole from the E pole by the tested product so as to generate a current from E to L pole. After I/V conversion and operation by the divider the measured insulation resistance value is directly displayed by LCD.

Insulating boots and gloves withstand voltage device is a power frequency power supply with low voltage working voltage of 220V/50Hz for insulating boots and gloves. According to the principle of electromagnetic induction, the input voltage is changed to the minimum value required for the test. high pressure. Insulating boots (gloves) withstand voltage test device generally consists of a special dedicated test box, an intelligent power frequency withstand voltage console, and a power frequency withstand voltage test transformer.
A special water tank can be customized according to needs to test 6-8 insulated boots or 6 insulated gloves at a time, and display the leakage current of the insulated boots or insulated gloves at the same time. The intelligent power frequency withstand voltage console is equipped with overcurrent protection and zero protection. Time protection and alarm function. The preventive voltage resistance test device for insulating boots and gloves is a special product developed and produced according to the needs of users according to the test procedures of insulating boots (gloves).
The selection has an automatic boost (buck) function, automatically reads the leakage current of each test product, the whole process is automatically completed, and the test data is automatically printed, which effectively solves the previous non-standard test methods, thereby simplifying .Simplifies the test procedure and improves the test speed. More reliable identification of parameters such as leakage current and power frequency withstand voltage of insulating boots (gloves). To ensure the safety of test personnel, it is an ideal pre-treatment of insulating boots (gloves) to protect power frequency withstand voltage test equipment.

In the production process of the multifunctional strand condition monitor, in order to ensure the quality of the slab, it is necessary to strictly control the performance and various parameters of the s guide roll within a certain error range. Due to the continuous casting machine is large and in a harsh production environment, it is difficult to measure the performance of the continuous casting machine manually, and many parameters are difficult to measure. Therefore, it is very important to have a set of equipment that can simulate drawing of steel billet to realize the measurement of various parameters and performance. The multifunctional strand condition monitor uses various sensors to realize the measurement of roll gap value, the arc value of continuous casting section, the rotation quality of the rolls, and the water spray pressure under the condition of simulating drawing of steel billet. Therefore, the quality can be controlled in real time, and it is convenient for the maintenance personnel to analyze the measurement results. The problem areas of the casting machine equipment can also be found. If these problems doesnt be found in time, it will cause the bad quality of products, the steel breakout in pouring process, surface and internal cracks and centerline segregation.

Electrical equipments in modern industrial, commercial and residential users are more sensitive to power quality, and have a higher requirement of quality of power supply. Currently, harmonics,electromagnetic interference, power factor reduction have been tied to the three hazard of the power system.
When it is interfered or contaminated, grid power quality can t reach the national standards, so it has to be targeted on the grid power quality improvement. To understand the actual situation of power quality, you must have the appropriate equipment to test and analysis the actual situation. Counter the domestic condition, our company developed the professional power quality analysis instrument, which is suitable for the country.
