SISCO 3 Phase Relay Tester User Manual.pdf

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 for using protection relay tester

1. When we start the relay tester, we need to warm up for 2 minutes. After shutting down, we should wait at least 1 minute before turning it on, otherwise it will damage the tester and cause the instrument to work abnormally.
2. We should ensure that the built-in test program of the tester is completed, and the power amplifier and DSP ready lights are on before starting the test.
3. The Protection relay tester should be waterproof and dustproof. It should be placed in a clean and dust-free place during the construction of the power station. When not in use, it should be carefully placed in the instrument box. When cleaning the surface of the instrument, turn off the power and wipe it carefully with a damp cloth.
4. The LCD screen on the test panel is a precision glass product, which should be used and handled with care to avoid heavy pressure and collision, otherwise it will cause damage and failure. The instrument and computer should be handled with care and managed by a special person.
