sf 6 check for leaks for HV MV

Traditionally leaks have been detected using a "sniffer" device to localise the leak location. However, the sniffer can sometimes be difficult to use in tight locations and as it is a contact type instrument, requiring the user to take the apparatus out of service to "sniff" for leaks near the high voltage circuit.
