Product Details

Features

1. Since the single-phase relay protection tester adopts microcomputer control, only 16 touch switches on the panel can conveniently complete various test functions, changing the drawback of the old relay tester that must turn off the power and switch multiple switches to convert power types. The operation is simple. This machine is also equipped with self-check and error reporting functions, greatly facilitating inspection and maintenance.

 2. This machine is equipped with comprehensive self-check and self-protection functions. After power-on, the machine immediately performs self-check. In case of overload and over-range, the protection circuit will quickly cut off the output and emit audible and visual alerts, greatly reducing unnecessary losses caused by misoperation.

 3. This machine has a high degree of intelligence. With just one key press, all parameters of a general relay can be measured, and all data can be automatically printed, freeing you from tedious testing operations.

 4. The display screen of this machine has a function display unit, which can clearly reflect the working status of the machine.

 5. All data printed by this machine are in Chinese characters, such as "pick-up voltage", "drop-out voltage", "normally open pick-up time", etc.
