ATO Relay Tester 

The ATO relay tester is a versatile and advanced tool designed for testing various types of relays and microcomputer protections. It can simulate a wide range of complex transient, permanent, and conversion faults for comprehensive testing. These testers are equipped with high-performance industrial control computers and feature large LCD displays for easy operation and clear visualization of test results. They support both standalone operation and connection to laptops, offering flexibility in how tests are conducted.

The ATO relay testers come in different configurations to meet various testing needs. For example, the 3-phase relay tester can output standard 4-phase voltage and 3-phase current, making it suitable for a variety of protection tests. It also has a GPS synchronization test function, allowing for coordinated testing at different locations. The 6-phase relay tester, on the other hand, is designed for more complex systems, offering 6-phase current and voltage output, which is beneficial for three-phase differential protection tests.

These testers are not only powerful in functionality but also user-friendly. They feature intuitive English operational interfaces and come with optimized keyboards and trackball mice for convenient operation. The software included with the testers is highly capable, supporting large-scale complex verification work, real-time data storage, vector graphic display, and online report printing. Additionally, the testers are equipped with independent dedicated DC power outputs to meet the DC operating power needs of relays or protection devices.

The ATO relay tester is a reliable and efficient tool for ensuring the proper functioning of relays in various electrical systems, providing both accuracy and ease of use for technicians and engineers.
