Traveling-Wave Fault Locating and Traveling-Wave Protection Testing—Generate nanosecond-precise current pulses to test traveling-wave applications, such as single- and double-ended traveling-wave fault locators and traveling-wave protection elements.
Compact and Portable Form Factor—Employ the SEL-T4287 in a laboratory or out in the field. The SEL-T4287 has a rugged housing with an adjustable carrying handle and comes with a universal ac power supply input, making it suitable for use in any location.
Precise Traveling-Wave Generation. Traveling-wave technology is based on precisely measuring wave front arrival times. In order to test the performance of a traveling-wave relay under various conditions, a precise test system is required. The SEL-T4287 generates traveling-wave pulses that are accurate to within 100 ns.
Traveling-Wave Application Testing. The SEL-T4287 is a standalone device that can be configured for laboratory or field testing of single- and double-ended traveling-wave fault locators. The SEL-T4287 also tests the traveling-wave differential (TW87) scheme and the traveling-wave directional (TW32) element in the SEL-T400L Time-Domain Line Protection. The test system features trigger inputs for coordination with other test sets as well as an IRIG-B input for synchronizing end-to-end traveling-wave tests.
Simple Test Configuration. Defining tests is quick and easy with an intuitive user interface. Traveling-wave test settings only require the line length, fault location, fault type, and traveling-wave line propagation time.
Ideal for Both Laboratory and Field Use. The SEL-T4287 has a rugged housing with an adjustable carrying handle and is designed to be used in a laboratory or out in the field. The universal ac power supply input allows you to use the SEL-T4287 in any location.
