Product Overview

The Light Digital Relay Protection Tester is suitable for those that comply withThe fully digital substation compliant with IEC 61850 standard not only outputs sampling value messages based on IEC 61850-9-2LE and IEC 60044-7/8, but also receives and transmits GOOSE messages.

Open AgreementBoth SMV and GOOSE messages support flexible configuration, enabling seamless connection with products from any manufacturer.

Please provide the Chinese content to be translated.In addition to the digital output of IEC 61850, the tester can also output a small signal analog quantity ranging from 0 to 7V. Moreover, the tester supports hard inputs and outputs, meeting the testing needs of low-voltage protection devices in digital substations.

Digital Outputs and Analog Outputs, Hard Inputs and OutputsGOOSE's diverse combinations can be easily configured to provide testing solutions for relay protection devices catering to various input/output methods.

Even in the outputAt 40mV, still maintainsExtreme.High precision, overall output accuracy meets0.05 grade requirement.
