6 Phase Protection Relay Tester, Relay Test Set

Q1: What is a relay tester?
A1: Relay tester is an important test tool to ensure the safe and reliable operation of power system. With the continuous expansion of the scale of modern power systems and the continuous improvement of the reliability and efficiency requirements of power system operation and management, the testing work of relay protection personnel has become more frequent and complex. The relay protection tester uses a high-performance industrial computer as the control computer, and directly runs the Windows operating system. The back panel of the device is provided with USB ports, network ports, serial communication ports, etc., which can facilitate data access, data communication and software upgrades.

Q2: What are the functions of protection relay tester?
A2: Protection relay tester needs to be able to respond to the faults and abnormal actions of electrical equipment, and can automatically, quickly and selectively act on the circuit breaker, remove the faulty device from the system, and ensure that the faulty device continues to work. And limit the incident to a minimum, improve the reliability of the system operation, and maximize the safety of the user's connection to the power supply. The role of relay test equipment is the role of automation equipment. "Normal" and "abnormal" operating conditions must be in the correct zone, as well as "external faults" and "internal faults" of the components to be maintained to complete the relay. Electrical maintenance function. Therefore, changes in various physical quantities reflected under various conditions can be detected and identified.

Q3: What are the advantages of relay tester?
A3: The relay protection tester has various forms in the output of current intensity, which can meet the characteristics of actual field experiments. Relay test set is not only compatible with each traditional experimental method, but also can easily carry out three-phase transformer differential protection experiments and factory power fast switching and standby self-switching experiments. Its powerful software functions can realize a variety of high-level automation technology, and large and medium-sized complex verification work. It also has the characteristics of its high-performance host and flexible output of current intensity, which greatly improves the detection production efficiency. Not only its real-time data digital signal processing ability is strong, and the operation speed is faster, but also the output waveform of the instrument equipment has high precision, small frame loss and good linearity. The function of the relay protection tester is to check whether the operation of the comprehensive relay can work normally, in order to verify the technicians find the problem early, and then deal with it in a timely manner to protect the normal operation of the overall power system.

Tips: How to choose a right relay protection tester?

According to the requirements of the relay protection tester, it can be divided into single-phase, three-phase, and six-phase relay protection testers. For the case where the use requirements are not high, a single-phase relay protection tester can be selected. The single-phase arc protection tester can only output single-phase current and voltage, and is suitable for tests with low voltage levels and low precision.

If there are relatively high requirements for the instrument, you can choose a six-phase electric protection tester. This relay protection tester can output six-phase current and voltage at the same time, and the test range can cover almost all transformers and relays.

The software system of the six-phase protection tester is more powerful. It can complete various complex calibration work of large enterprises with a high degree of information automation, and can easily test and scan various environmental protection values, process fault playback, and store test results in real time, display vector diagrams, print technical reports online, etc. The six-phase electric protection tester has an independent dedicated DC power output, and has a dedicated adjustable DC power output of 110V and 220V. The interface is complete. The device is equipped with a USB communication port, which can communicate with computers and other external devices. Ecological function protection, scientific and rational optimization design of heat dissipation structure, reliable and complete hardware resource protection policy measures, soft start function of important power supply, software self-diagnosis method for fault problems and cultural output blocking and other functions.
