Customer: NTDC Lahore Date: 27.02.2011

Substation: Ravi Grid Reported by: Urs Sommer

GIS Type: B212-4

Country: Pakistan

According the information from NTDC personal, Friday night 25.02.2011 was an incident and the

cb D06-Q0 tripped. During Saturday 26.02.2011 NTDC personal was metering the SF6 purity and

the result was 94.1%. NTDC personal replaced the gas with new one (purity 98.1%).

Customer called to inform me that there was another incident and I was on site at 20:30h. The

situation was that the rupture disk of cb D06-Q0 phase A was busted. Additional I found the BB I

isolating switch D01-Q1 not in definitive OFF position. With the test pin I could confirm this

irregularity of isolating switch. Fact is that additional to the cb D06-Q0 the added bus bar isolating

switch D06-Q1 (both phase A only) is demaged as well.

NTDC needs urgent the necessary information from ALSTOM GRID which are the next steps.
