Product Details

Product Overview

Optical Digital Relay Protection Tester It is based on the… DL/T624-2010 Technical specifications related to the microprocessor-based relay protection testing device. Standardized design, while also based on IEC61850 A relay protection testing device implemented using advanced computer technology, integrated within a communication standards framework.

The product is equipped with a high‑performance power amplifier and built on a robust PowerPC+X86 platform. Featuring a modular design, it boasts powerful functionality, high precision, compact dimensions, and lightweight construction. It can test the functions and performance of merging units, relay protection devices, measurement and control devices, and intelligent terminals, making it suitable for power plants, substations, various research institutions, and equipment manufacturers.

Product Technical Features

  1. Intelligent Testing Module

Supports intelligent test template editing; during testing, you can add test items at any time and save them as reusable test project files, thereby… Test efficiency during the post‑high‑level inspection and defect‑resolution phase.

  1. Automated testing

It features localized protection and digital protection automatic testing capabilities, enabling all test items for a single protection device to be completed with a single click.

  1. Digital quantity / Analog output

It can be used to test the merging units, protection devices, measurement and control units, and intelligent terminals of digital substations, as well as simulated protection devices and generator-transformer units. The device is being tested;

  1. Simultaneous output of analog and digital signals

Supports simultaneous output of analog signals, SV, and FT3, as well as the transmission and reception of GOOSE messages.

  1. Multiple scanning modes

It supports testing of amplitude, phase, frequency, impedance, vectors, sequence components, and power, either manually or automatically, and also supports stepwise testing. Automatic variation tests are conducted using methods of variation, slip difference, and comprehensive approaches.

  1. Security and Alarm

It features over‑temperature and overcurrent protection; the current source provides open‑circuit protection and an open‑circuit alarm, while the voltage source offers overload and short‑circuit protection.

  1. Graphical display of virtual terminals

Supports graphical visualization of virtual terminals, ensuring clear and intuitive data flow.

  1. Simultaneous transmission and reception of messages

Support IEC 61850-9-1, IEC 61850-9-2 and GOOSE Optical digital message output. GOOSE The signal can be transmitted and received independently, or it can share a single optical Ethernet interface with IEC 61850‑9‑2.

  1. FT3/ Expand  FT3

Support FT3, FT3 Extension and DL/T 282 Message output, and it supports 2M/4M/6M/8M/10M/15M/20M Baud rate UART Encoding and 5M/10M/20M Manchester encoding;

  1. Exception Testing

It features simulated message‑anomaly capabilities, enabling tests for quality‑related anomalies, transmission‑rate jitter, latency irregularities, packet loss, synchronization loss, sequence‑number jumps, maintenance mode, and spurious state changes.

  1. Fault Playback

Supports fault simulation and COMTRADE‑format data playback;

  1. MMS   Service

It features MMS setting read/write functionality, enabling the reading and writing of configuration information such as settings for intelligent IED devices.

  1. Timekeeping and Time Synchronization

Equipped with synchronous triggering functionality, it supports direct connection. GPS/BD Antenna time synchronization is also supported. IRIG-B, PPS and PTP 1588 Time synchronization method And it can also support external output. IRIG-B, PPS and PTP 1588 Time signal;

  1. Hardwired input and output contacts

The input channels are active‑ and passive‑type adaptive contacts, automatically detecting the input type and voltage. The channels are electrically isolated from one another, and a reverse polarity connection triggers an alarm notification.

  1. Message Reception and Analysis

It features packet reception and analysis capabilities, allowing received packets to be opened and analyzed with ZHNPA or exported.

  1. Single-fiber mode

The optical port supports single-fiber transmission and reception, and enables optical power testing.
