The RPT-005 is a high-performance portable single-phase relay tester. Its aluminum alloy body and PC panel design offer a rugged yet lightweight design (weighing 18 kg and measuring 340 × 270 × 260 mm). Equipped with an ARM chip and a 320 × 240 green LCD display, it supports fully isolated AC/DC voltage and current outputs (AC voltage 0-250 V, DC voltage 0-300 V, and current 0-250 A adjustable). Dual overload protection and an internal electronic stopwatch ensure safe testing and accurate data.
The RPT-004 is a six-phase microcomputer protection relay tester designed for smart grid applications. It offers 6-channel AC current (0-30A) and 6-channel AC voltage (0-130V) with high precision, covering a 0-1050Hz frequency range and ±0.05° phase accuracy. Supporting COMTRADE fault replay and multi-vendor protection device testing (e.g., ABB, Siemens), it is ideal for substation commissioning and relay protection calibration.
