Advantages of Relay Protection Tester
The relay protection tester has various forms in the output of current intensity, which can meet the characteristics of actual field experiments.
Relay test set is not only compatible with each traditional experimental method, but also can easily carry out three-phase transformer differential protection experiments and factory power fast switching and standby self-switching experiments.
Its powerful software functions can realize a variety of high-level automation technology, and large and medium-sized complex verification work.
It also has the characteristics of its high-performance host and flexible output of current intensity, which greatly improves the detection production efficiency.
Not only its real-time data digital signal processing ability is strong, and the operation speed is faster, but also the output waveform of the instrument equipment has high precision, small frame loss and good linearity.

Usage Requirements
The relay protection tester device has built-in industrial computer and Windows 7 operating system, please do not switch the host power supply too frequently.
The panel of the relay protection tester is equipped with a USB socket, which allows hot-plugging and plugging of USB port devices (such as U disk, etc.), but pay attention to the plug-and-plug after the data transmission is completed.
The relay protection device is equipped with a dedicated self-recovery CF card to avoid operating system damage caused by illegal shutdown, deletion or modification of files on the hard disk and icons on the desktop.
When connecting an external keyboard or mouse, please do not insert the wrong port, otherwise the Windows operating system will not start normally.
Do not directly turn off the power supply in the output state, so as to avoid the protection malfunction due to the output error when turning off.
When using the relay protection tester, do not block or close the air vents of the fuselage, generally place the instrument standing or open the supporting feet and place it slightly inclined.
It is forbidden to introduce external AC and DC power into the voltage and current output jacks of the tester. Otherwise, the tester will be damaged.
If the interface data is wrong or the device cannot be connected during the use of the relay protection tester, it can be solved in this way: press the reset button down to reset the DSP; or exit the running program and return to the main menu and run again program, all data on the interface will be restored to default values.
