Statistical Analysis Of Overvoltages Due To The Energisation Of A 132 Kv Underground Cable, M Z. Daud, P Ciufo, S Perera
Faculty of Engineering and Information Sciences - Papers: Part A
Analysis by means of simulation studies is essential for providing useful information to distribution engineers and researchers regarding high frequency switching transients in cable systems. The behaviour of transients due to switching is strongly dependent on the pole closing span of the circuit breaker and also the closing angle of the power frequency voltage. This behaviour requires the study of overvoltage magnitude distributions to be carried out using a statistical approach. This paper presents an analysis of overvoltage sensitivity due to circuit breaker operations when energising an unloaded 132 kV underground cable system. Based on two approaches, the overvoltage values …
Survey Response As Organisational Behaviour: An Analysis Of The Annual Enterprise Survey, 2003-2007, Walter R. Davis, Nathaniel Pihama

Non-response is a matter of great concern to national statistical offices and a key issue for any survey because it can introduce bias to survey estimation. However, in this presentation, we focus on a business's decision to participate in a survey as an example of organisational behaviour and draw on basic organisational theory to explain why businesses may not respond to surveys (eg Tomaskovic-Devey et al 1994). The data are drawn from the Statistics New Zealand Respondent Management System, which links the response history of individual businesses in all Statistics NZ surveys with information from the Statistics NZ Business Frame. …
