This high-precision relay protection tester has core advantages that solve the pain points of traditional laboratory testing. First, it has a measurement accuracy of 0.05 level, which can meet the calibration requirements of national first-class metrological institutions. Second, the synchronization error between channels is controlled within 1ms, which can accurately complete the joint debugging test of multiple relay protection devices. It supports the simulation of various complex power waveforms, including harmonic waves, transient waves and DC bias waves, which can fully detect the performance of relay protection devices under various working conditions. In addition, it is equipped with professional data analysis software, which can automatically generate standardized test reports and support direct export to metrological certification systems.
The product specifications of this bench-top high-precision relay protection tester are as follows: overall dimension is 480mm*380mm*220mm, net weight is 18kg. It supports single AC 220V ±10% power supply. The display is a 10.1-inch TFT touch screen with a resolution of 1920*1080. The built-in storage can store up to 5000 sets of test data. The test channel configuration includes 12 current channels (0~100A) and 12 voltage channels (0~1200V), with a measurement accuracy of 0.05 level. The standard communication interfaces include Ethernet, USB 2.0 and GPIB, and the protection grade is IP30, which is suitable for clean laboratory environments.
This bench-top high-precision relay protection tester is mainly applicable to professional power testing scenarios. It can be used for type testing and regular calibration of relay protection devices in national metrological institutions, power scientific research institutes and power equipment manufacturing enterprises. It is also applicable to the acceptance testing and performance verification of relay protection devices in 110kV and above substations, and can provide professional testing support for the development and optimization of new relay protection products.
