Aiming at the requirements of high efficiency, high reliability in testing electrical modules of in-vehicle network, Based on CAN network environment of passenger-cars in Beijing Automotive Technology Co., Ltd.(BATC), by means of IPC-610L, vehicle protocol tester Tellus™ Pro(Tellus), CAN bus interference generator CAN Spider, programmable power supply, self-made relays module, Digital I/O cards, diagnostic...
This paper highlights some important design aspects that a Protection and Control system should have when applied to protecting a Smart Grid or Smart Transmission & Distribution Substation. These aspects are aimed at de-risking the designs and, at the same time, reducing overall project cost. The electricity industries of many countries currently only put equipment into service following thorough...
The philosophy of testing relay protection systems has changed very little in most utilities. However the devices themselves have changed greatly. Testing for some devices has been called into question as no testing at all has been proposed. This paper reviews why we tested in the past and what methods were used. The paper further reviews future testing needs and strives to bring a resolution to the...
This paper discusses the role of three-phase primary injection testing as an important part of the substation commissioning process. Individually testing the components of a protective relay scheme is common practice. Many times, this testing is performed without looking at how the equipment under test interacts with all the other components of the protective relay scheme. Several relay misoperations...
The most research on the power supply test was aimed at the fields of aviation and communication now, but it had not seen similar test system of the missile. To address this problem, the measurement theory and achievement method of the secondary power supply test system based on PXI bus were elaborated in the paper. On the basis of analyzing the function and the quota of the system, the hardware platform...
The UK-2/S-52 Satellite is one of NASA's International Satellites and carries Experiments built by the British. The satellite is under Management and technical supervision of Goddard Space Flight Center. The Consideration and analysis of environmental and operational requirements, as well as the requirements imposed by the satellite configuration, influenced the UK-2/S-52 power source system design,...
