Re-appraisal of the Basic Impulse Level (BIL) for 400 kV Underground Cables Using EMTP/ATP
نویسندگان
چکیده
This paper investigates the lightning impulse duty for 400 kV underground power cables using EMTP/ATP and re-assesses the recommended design level based on probabilistic analysis. The work is a part of a larger investigation that will study by computer simulation, the full range of transient overvoltages due to lightning, switching, faults and other temporary overvoltages (TOV) on cables within National Grid’s transmission system.

Transformer in Grid
The aim of this research article is to determine the way to install surge arresters close to a power transformer to provide protection against lightning overvoltage. Depending on the length of the cables used in the installation, the insulation levels in base insulators of surge arresters and bushings of transformers change according to the voltage they support. For validation purposes, the vol...
متن کاملA New Method to Improve the Sensitivity of Leak Detection in Self-Contained Fluid-Filled Cables
The condition of a 400 kV underground FF cable route within the National Grid transmission network has been monitored by Drallim pressure, temperature and load current measurement system. These three measured variables are used as parameters to describe the condition of the cable system. In the regression analysis the temperature and load current of the cable circuit are used as independent var...

This paper presents a fault identification, classification and fault location estimation method based on Discrete Wavelet Transform and Adaptive Network Fuzzy Inference System (ANFIS) for medium voltage cable in the distribution system. Different faults and locations are simulated by ATP/EMTP, and then certain selected features of the wavelet transformed signals are used as an input for a train...
متن کاملATP-EMTP investigation of a new algorithm for locating faults on power transmission lines with use of two-end unsynchronized measurements
-This paper presents an algorithm for locating faults on two-terminal power transmission lines. Unsynchronized twoend voltages and currents are processed in the algorithm for determining the distance to fault and the synchronization angle. The calculations are performed initially for the lumped model of the transmission line. Then, these results are used as the initial data for the Newton-Raphs...
متن کاملPartial Discharge Simulation and Analysis Based on Experiment in Underground Distribution Power Cables
This paper describes the simulation and experiment for partial discharge (PD) pulse propagation in 22.9kV CNCV power cables. To investigate the propagation characteristics of PD, experiments are carried out by injecting the PD pulse in 100m-long 60 mm 2 CNCV cable in the laboratory. The characteristics of PD are also simulated using EMTP to investigate and analyze PD in the same cable. By compa...
