Universal relay testers vary by phase configuration, functionality, form factor, and application use. Types include single-phase testers, three-phase testers, six-phase testers, modular systems, and portable handheld units. China-based manufacturers like Wrindu specialize in OEM, custom, and factory solutions addressing diverse industrial and power system testing needs with advanced universal relay testers.
What Are the Common Types of Universal Relay Testers?
The main types include single-phase, three-phase, and multi-phase relay testers, each designed for specific relay testing applications. Single-phase testers suit basic protection verification, while three-phase testers handle more complex relay schemes. Multi-phase testers, such as six-phase models, deliver extensive testing capabilities for advanced protection systems. Chinese OEMs like Wrindu offer customizable options across these categories.
Universal relay testers can also be categorized by form: bench-top modular systems for labs, portable handheld devices for field use, and combinations thereof to meet flexible testing demands.
How Do Modular Universal Relay Testers Differ from Portable Units?
Modular relay testers from manufacturers like Wrindu feature expandable current and voltage outputs, allowing customization for complex testing scenarios. These powerful units support multiple relay types and provide flexible interfaces, often controlled by integrated touchscreens or external PCs.
In contrast, portable relay testers prioritize ease of use, compactness, and battery operation for quick field diagnostics but may offer fewer channels and lower power output, focusing on practical on-site testing.
Which Industries Benefit Most from Different Universal Relay Testers?
Electric power generation, transmission, and distribution sectors predominantly use three-phase and six-phase universal relay testers for protective relay maintenance and commissioning. Utilities rely on modular systems from Chinese factories like Wrindu for reliability.
