225 CONDITION MONITORING OF 132 kV TRANSFORMERS M K Domun EA Technology‚ UK 1. INTRODUCTION Approximately 3 0 % of the 132 kV grid transformers in the UK are over 40 years old. Some 8 0 % are over 20 years old. To date‚ performance has been satisfactory with negligible occurrence of serious failure. However‚ transformer loads are increasing and reserved capacities are decreasing. Consequently‚ it is imperative to have some simple and practical means of assessing the insulation integrity

film resistors: This resistor is formed by depositing a carbon film layer on an insulating substrate. Helical cuts are then made through the carbon film to trace a long and helical resistive path. The resistance can be varied by using different resistivity carbon material and modifying the shape of the resistor. The helical resistive path make these resistors highly inductive and of little use for RF applications.

DEVELOPMENT OF AN INDUCTION COOKER. J. Schedel‚ I. Khan( and E Uken( Naval Engineering Services‚ Cape Technikon( ABSTRACT This paper entails the development of an industrial induction cooker. The induction cookers output power is to be controllable over the full desired operating range. The cooker is also to function with all ferrous vessels. The cooker consists of three main components‚ namely the load‚ the inverter stage and the control stage. This paper also briefly discusses the

alters the resistance. The resulting principle is used in the resistance strain gauge‚ which consists of many turns of resistance wire‚ wound on an insulating former‚ the strain gauge wire is selected for the minimum temperature coefficient of resistivity. They may be used to measure extremely small displacements‚ of the order of nanometres. Strain gauges are classified as bonded or non-bonded. The bonded type has a wire mounted on a paper backing and the paper could be pasted to the surface of the
