Portable Distribution Automation Terminal Tester

Product Overview

portableDistribution testerIt is a handheld power distribution automation tester positioned as lightweight and portable, especially suitable for testing scenarios that require flexible movement. On the basis of retaining the high-power and high-precision power amplifier output of traditional distribution automation testers, innovative lightweight design is adopted to improve the internal structure, optimize hardware configuration, reduce volume, and lighten weight.

Portable Distribution Automation Terminal TesterBased on relevant standards in the distribution network industry, the device is designed and developed using a built-in large capacity lithium battery for power supply, with a continuous output of 10A for no less than 4 hours. It meets the requirements of on-site portable testing; The voltage, current output, input and output interfaces of the device can be used to perform some performance tests on the distribution terminals. Mainly used for on-site secondary circuit operation and maintenance, it is particularly suitable for fast closed-loop debugging and acceptance work before and after the installation of distribution terminal FTU and DTU. It is a set of testing equipment that follows the domestic industry testing outline standards, has a high degree of automation, and is technologically advanced. By automatically testing the performance and functionality of terminals according to the IEC101 and IEC104 protocols, it is possible to verify the protection logic of distribution terminals. The built-in high-precision GPS synchronization function fully supports on-site feeder automation testing such as voltage time type, voltage current type, and adaptive comprehensive type.

Voltage and current are isolated from each other, facilitating line voltage output.

Comprehensive functionality: supports three remote tests, status sequence, simulated circuit breaker, protection function, protocol and other tests

The simulation master station has the function of power distribution simulation master station, which can communicate with FTU and DTU, read protection setting parameters and pressure plate status, and support modifying setting values and switching pressure plates. Support project management, personnel permission management, testing task management, and distribution terminal case management.

The waveform recording function can remotely set the starting condition parameters of the distribution terminal. Through overcurrent faults, line voltage loss, zero sequence voltage, zero sequence current sudden changes, etc., the device can record waveforms and perform both steady-state and transient waveform recording functions and performance testing.

Optional built-in lithium battery pack, capable of running at full power for more than 4 hours on a single machine. You can also choose to use mains power directly without lithium batteries.

The device adopts a large amount of advanced technology and precision component materials, and has undergone specialized structural design, resulting in small size, light weight, comprehensive functions, and easy portability. It can work immediately after startup and flow testing is very convenient.

The output end of the new high fidelity linear power amplifier has always insisted on using high fidelity and high reliability modular linear power amplifiers, rather than switch type power amplifiers. It will not cause high or medium frequency interference on the test site, and ensures smooth waveform accuracy from high current to low current throughout the entire process.

Portable Distribution Automation Terminal TesterThe output part of the high-performance host is controlled by DSP, ensuring an output accuracy of 0.05% for voltage and current. Fast computation speed, strong real-time digital signal processing capability, wide transmission bandwidth, and control of high-resolution D/A conversion. The output waveform has high accuracy, low distortion, and good linearity.

There are a variety of switch contacts, including 4-channel input and 2-channel output. The input contacts are empty contacts and compatible with 0-250V potential contacts, which can be intelligently and automatically recognized.

The interface is complete with two USB ports and two network ports, which can communicate with computers and other external devices. It is equipped with a built-in 4G module for remote control.
