Grounding of Impulse Testing Laboratories

Grounding of Impulse Testing Laboratories: An earth or ground system means an established stable .reference potential normally taken to be zero. There are three types of Grounding of Impulse Testing Laboratories are: the ideal ground, single point ground (Fig. 11.4a), and the bus ground (Fig. 11.4b). Of all these, the best ground is the ideal […]

Operation of UHV Laboratory

Operation of UHV Laboratory: Operation of UHV Laboratory are designed as indoor laboratories or outdoor laboratories depending on the specific requirements. An indoor laboratory is preferred when most of the equipment testing and associated research work is carried out indoors, whereas outdoor laboratories are preferred when the electrical and mechanical parameters of the UHV transmission […]

High Voltage Laboratory Rating

High Voltage Laboratory Rating: The High Voltage Laboratory Rating and size of test equipment chosen in the h.v. laboratories depends on the test facilities to be provided. Normally, the design of the laboratories for 230 kV system voltage and below does not pose any problems, but laboratories intended for system voltages of 400 kV and […]

Classification of High Voltage Laboratories

Classification of High Voltage Laboratories: Classification of High Voltage Laboratories depending on the purpose for which they are intended and the resources (finances) available, can be classified into four types. Small laboratories Medium size laboratories Large general purpose laboratories UHV laboratories Some salient features of these various types of laboratories are discussed below. 1.Small Laboratories: […]
