Six Phase Relay Protection Tester

JHS1300 is a professional six-phase relay protection tester and dedicated secondary injection testing equipment designed for power system protection debugging, featuring 6-phase voltage (125V/phase) and 6-phase current (30A/phase, up to 180A in parallel) output. It adopts a Windows 7 interface, 8.4-inch true color display, and DSP+FPGA core control, supporting tests for traditional relays and modern microcomputer protection devices. Compliant with DL/T624-2010 standards, it has high accuracy, rich test functions, and a portable design, ideal for on-site maintenance and debugging.

The JHS1300 six-phase relay protection tester is a high-performance intelligent device tailored for power system protection testing. It delivers 0-125V AC voltage and 0-30A AC current per phase (6-phase parallel up to 180A), with 0.2% measurement accuracy and a wide frequency range of 0-1000Hz, fully meeting DL/T624-2010 standards. Equipped with a high-performance embedded industrial computer and Windows 7 system, it ensures stable operation. The tester integrates over 20 test modules, including AC/DC test, differential protection test, and fault recurrence, suitable for transformers, lines, and generator sets. It also provides an independent DC auxiliary voltage source (110V/220V) and 8 pairs of digital input/4 pairs of digital output terminals, with software self-calibration for long-term accuracy. Featuring a metal industrial keyboard, touchpad, and three USB interfaces, it enables easy operation and data access. Weighing 18kg with compact dimensions, it is convenient for on-site use. The product offers reliable performance and comprehensive functions, providing efficient and accurate testing solutions for power industry users.
