“HZJB-1600B Relay Protection Tester”firstly integrate the MMS protocol into the test system, which realizes the real-time automatic reading and writing protection device setting, test parameters setting, soft pressure plate of the drop device to match the current test project, and automatically completes the whole test process. This technology is the key technology of automatic testing.

Ø Manual test and automatic test dual mode

n Manual test

“HZJB-1600B Relay Protection Tester”provides a variety of general test modules, protection test modules and special test modules, providing perfect test solutions for various types of secondary equipment in substation, including relay protection devices and other safety automatic devices. At the same time, it adopts the engineering configuration interface and configuration process similar to the intelligent substation SCL configuration tool, which conforms to the testing habits of the operators, and provides various types of graphics and forms for displaying the test progress and test results, greatly improving the efficiency of the test.

n Automatic test  

“HZJB-1600B Relay Protection Tester”adopts template-based management scheme to manage automatic test solutions. A test template can contain multiple test items. Each test template is configured for a type of protection. After the template configuration is complete, the user does not need to perform other manual settings, and can complete the automatic test of all test items with one key click Start, and automatically give the test results. Because it is a test template configured for a certain protection device, the template can be used for automatic testing of other types of protection without reconfiguration, improving the reuse rate and test efficiency of the automatic test template.
