测量电气设备的绝缘是电力运行人员经常进行的一项工作,绝缘合格是电气设备能否投入运行的一项重要指标。 绝缘就是使用不导电的物质将带电体隔离或包裹起来,以对触电起保护作用的一种安全措施。简单的说电气设备…
The insulation test is carried out at 500volts d.c for a period of 5 seconds. All PAT testers that carry out this test do so by shorting together internally the live and neutral pins within the appliance when carrying out the test. This means that there is no potential difference between ...
This type of insulation resistance test can be simply performed by connecting a Megger device across the insulation which needs to be tested. After that, it is operated for a short time period, generally 60 seconds. Throughout this test, it is most significant to keep in mind that humidity,...

HV insulation test machine 1.AC DC withstanding voltage tester Introduction Withstand voltage tester is an ac high voltage safety measurement instrument, widely used in electronic instruments, electronic equipment, electronic components, electrical equipment, bakelite appliances, rubber, high voltage cable...
Test Voltage 0.5,1,2.5,5,10,20kv Voltage Accuracy ±(5%+10V) Short-Circuit Current 10mA Range 20mΩ - 2000gΩ Resistance Measurement Range 0.5 - 1999 GΩ by Subsection Accuracy ±(5%+5digital) Anti-Electric Field Interference Ability 2mA(50Hz) ...
This device can test insulation resistance (such as transformer, switchgear, lead, motor) of different modules in one system, to insulate and repair failure components. It is important to ensure products quality and security of person and equipments during operation by insulation test of c...
A contact condition is replaced to share insulating states between a plurality of electrodes to be tested, and decided. Thus, the test is accelerated, and reliability of a semiconductor device can be enhanced. 展开 收藏 引用 批量引用 报错 分享 ...
11.Internal rechargeable lithium battery power supply or ac power supply, real ac and dc dual-use does not affect the test accuracy. 12.The analog pointer coexists with the digital display, and the number reflects the accuracy of the insulation resistance of the tested product, and the analog...
电器绝缘耐压测试(Insulationwithstandvoltagetestof electricalequipment) 耐压测试(耐压试验)也就是俗称的高压测试 电器产品的耐压测试 在CSA,UL和IEC标准中,几乎各种电器安全标准都会要求对产品进 行耐压测试。这就可以看出耐压 测试是电器安全标准的一个重要组成部分。耐压测试(耐压试验)也 ...
