Sustainable Initiative - Go Green Conception Testing of High Voltage Cables

Asraf Ali Syeed, Abdul Rasheed, Maher Al Ejel

Abstract: This paper presents a general overview about innovative testing method by optimization of SF6 gas handling in DEWA (Dubai Electricity and Water Authority PJSC) substation during high voltage testing of 132Kilo Volt cables between transformer and gas insulated switchgear. There are 300+ DEWA substations in operation feeding electricity to900, 000 consumer. DEWA substation is fully indoor and Gas insulated switchgear filled with SF6 gas is used in 400KV and 132kV substation. Using the conventional standard practice of High voltage testing method, there are high possibilities of SF6 gas emission to atmosphere. Initial aim focused on how to optimize the SF6 gas handling in DEWA substation and to predict these radiated fields and examine their compliance with international standards. An innovative model using the same technology with change in work nature has been identified as an alternative. An exposure assessment of a new innovative testing method conducted practically at DEWA substation with the one of the makes of gas insulated switchgear available in system. In a second step, we studied the technical viability confirming with the international standard and obtaining stakeholder confirmation which helped to implement the developed idea to deployment.

Keywords: Gas insulated switchgear, cables, High voltage testing method and Test adaptor device
