What is An Insulation Resistance Tester? Insulation resistance tester is an important technical tool to measure the protective capacity of electrical systems. It evaluates the electrical system insulation by the application of direct current voltage on the measured insulation surface. It can be used to detect new electrical equipment failure as well as to ensure effective operation of running elec...
What is withstand voltage test? Withstand Voltage Test is a common method for testing the insulation capability of electrical appliances, electric equipment, electrical devices, and electrical circuits. Withstand Voltage Test is divided into two types: AC Withstand Test and DC Withstand Test. The former uses test voltage several times higher than the rated voltage of the tested product, while the ...
Introduction Digital oscilloscopes have revolutionized the electronics industry by allowing precise measurement and analysis of electrical signals for design and troubleshooting purposes. Although learning to read fundamental waveforms on a digital oscilloscope is important, understanding sophisticated measuring methods may greatly expand the instrument’s usefulness. In this post, we’...
What is A Ball Pressure Test Ball Pressure Test is a safety regulation test to examine the heat-resistance performance of product materials. The temperature of the test is usually 125℃ and it is mainly aimed at increasing the product safety. The ball pressure test is to press the surface of non-metallic and non-ceramic materials at high temperatures using a ball pressure tester to detect the ...
The rapid temperature change test chamber is suitable for testing various performance indicators of products in aerospace, information electronics, instruments and meters, materials, electrical engineering, electronic products, and various electronic components under rapid temperature changes. The rapid temperature change test chamber is mainly designed for the adaptability testing of electrical a...
Ozone Test Chamber is a kind of testing equipment used for aging test of rubber materials with ozone. It is widely used in rubber aging test, mainly for vulcanized rubber, thermoplastic rubber, cable insulation protection sleeve, electrical shell and other rubber products. LISUN Ozone Test Chamber (or called Ozone Aging Chamber and Ozone Aging Test Chamber) is design according to rubber being ...
What is Leakage Current? Leakage current is the current flow going through a piece of insulating material when certain voltage is applied. It can be used to estimate insulation resistance in power systems, since almost none insulation material can be 100% nonconductive. The flow of leakage current indicates the losses of voltage in insulator, thus the determination of its insulation performance ca...
The colorimeter and glossmeter developed and produced are optical testing instruments. The reason why these instruments can measure the color difference, gloss, chromaticity, and image clarity of various products is due to the optical principles of their internal design. Learning optical knowledge is very helpful for the use and analysis of color difference meters and glossmeters. People can see t...
The ozone aging test chamber is an essential testing equipment in the rubber industry, used to test the ozone aging resistance test performance of products. According to different customer test requirements, we can also be divided into static and dynamic two types. What precautions should be taken when installing an ozone aging test chamber? 1. Site conditions The site for installing the ozone agi...
