China High Quality protection relays tester Suppliers – GDJB-6000M Smart Substation Relay Protection Test System – HV Hipot

GDJB-6000M Smart Substation Relay Protection Test System is a new generation of intelligent relay protection tester designed according to “Smart Substation Relay Protection Technical Specifications” and “Smart Substation Technical Guidelines”. It can not only realize the full function test of the optical digital protection device (IEC61850, smart digital station), but also carry out full function test on the traditional protection device (conventional station).

GDJB-6000M is a portable new product independently developed through the use of technologies such as embedded real-time operating systems, high-performance embedded processors, and large-scale logic devices, combined with power field conditions and numerous power user experiences. It is widely applicable to power plants, substations, equipment manufacturers, enterprises and institutions, as well as other research institutes that need to carry out relay protection testing or inspection.

GDJB-6000M adopts an engineering management scheme to manage the test; project management adopts a three-layer model of protection equipment, protection type, and test point to manage the test. The structure is very clear; It supports analog output, and can simultaneously carry out the output of the analog quantity and send & receive GOOSE messages; Provides multiple ways to configure SV and GOOSE messages, including manual settings, network detection, and importing SCL files; The optical digital message has a very flexible configuration of the transceiver, which can send multiple SV and GOOSE messages with 1 optical port, and the same SV and GOOSE messages can be sent through multiple optical ports.
