Study on Lightning Intruding Overvoltage in Yantan Extension Substation
500kV substation is especially important to the grid of our country, once it encounters lightning damage, the safety and reliability of the whole power system will be directly affected. As lightning intruding waves will cause overvoltage on electric equipments by intruding from the transmission line or straightly stroking the substation, which seriously influences the insulation level of equipm...
متن کاملSolid State Bipolar Marx Modulators: Overvoltage Tolerance Capability
Two solid-state bipolar Marx modulators are compared in terms of semiconductors overvoltage tolerance capability in abnormal operating conditions such as switching synchronization failure. Simulation results are presented for 4 stages of two Marx circuits using 500 V per stage with 1 kHz bipolar pulse repetition rate, with 5 μs pulse width and 10 μs relaxation time into resistive load.
متن کاملOvervoltage protection and voltage stabilization for Motion Control terminals
This application example describes how Motion Control applications with the output stages for servo, DC and stepper motors by Beckhoff are optimized by the utilization of buffer capacitors. The buffer capacitor terminals EL9570 for EtherCAT and KL9570 for K-Bus stabilize the voltage supply by absorbing the fed back energy and dumping the energy that the buffer capacitor cannot protect against i...
متن کاملCoordination of Overvoltage Protection in Low-Voltage Residential Systems
This paper was presented as a summary tutorial aimed at the French-speaking Canadian community to solicit their comments on the development of the IEEE Std 587 Guide. The paper has been translated into English by the author to make the English-speaking community aware of that paper, which served at that time as one output for the release of the extensive test results that were reported in the 3...
متن کاملTransient overvoltage protection: The implications of new techniques
The paper presents a comparison of the performance of voltage-switching devices and voltage-limiting devices for late seventies-vintage SPDs as marketed and installed in service panels in the USA and in Europe. Artifacts in the response of a typical oscilloscope to a nearby gap sparkover, and the effect of lead dress inside the panels and outdoor installation are described. Predictably, the per...
