Secondary Injection Relay Test Set

The secondary defect elimination tester HZJB-1700 is controlled by a microcontroller, which makes it simple to use and convenient to carry. It can be used to test the action values and time of AC relays. Additionally, it can test the protection functions of low-voltage microcomputer-based line protection systems, such as re-pressurization blocking, direction overcurrent, zero-sequence overcurrent, low-cycle load reduction, and full transmission protection of high-voltage microcomputer-based line protection. The tester can also be used to check the start value, quick-break value, and second harmonic inrush blocking value for the differential protection of microcomputer-based transformers.

The HZJB-II Single Phase Relay Protection Tester is a portable field testing device with excellent performance. It features an elegant, polished appearance with an aluminum alloy chassis and PC panel. Controlled by an ARM chip, the tester has an LCD screen that displays voltage and current outputs, as well as a stopwatch.

The instrument provides fully isolated outputs for adjustable AC/DC voltage, AC/DC current, and adjustable DC voltage. It also features double overload protection in the output loop, ensuring safety and reliability. With its high output capacity, small size, light weight, and high reliability, the HZJB-II is ideal for field calibration and testing of various relays.

Six phase voltage and six phase current can be output, which has made it is possiable to be any combition, such as the output mode of the combination of conventional four phase current and three-phase current, six phase voltage mode, six phase current mode and 12 phase output mode. It not only can be compatible with the traditional way of various tests, but also can conveniently carry out differential test of three-phase transformer.
