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.
The RPT-002 relay protection tester integrates advanced technology and user-friendly design. It is equipped with a 9.7-inch true color TFT LCD touch screen and supports independent operation without a laptop. It has 10 channels of high-precision output and can simulate complex electrical environments. It strictly follows international and industry standards such as IEC 62271-203 and MT/T 845-1999, provides 3 years of free repair and lifetime maintenance services, and is an ideal choice for power system relay performance testing.
RPT-001 relay protection tester has the function of energy meter calibration (hardware ready to activate). The equipment strictly complies with IEC 62271-203 and other standards, has precise voltage and current output, advanced frequency phase control, and rich input and output interfaces. It provides reliable guarantee for relay performance testing, and also provides 3 years of free repair, lifelong maintenance and free software upgrade services.
