Gas Filled High Voltage Relays

 Gas Filled High Voltage Relays

These relays also provide high dielectric strength and avoids the oxidation. 

Therefore, these are ideal for high inrush make and capacitive discharge loads such as cable test equipment, ESD test equipment, heart defibrillators, etc. 

In these relays, a mixture of SF6, sulfur hexa fluoride and nitrogen is used as gas medium. 

But arc is formed in this relay when the contacts get opened and sustained for longer durations, compared to the vacuum relays.

Along with the above types, time-delay relays can also be differentiated depending on normally open or normally closed contacts with the time delay in the direction of closing or opening. 

These are of different types like normally-open timed-closed contact (NOTC), normally-open timed-open (NOTO), normally-closed timed-open (NCTO) and normallyclosed timed-closed (NCTC) contact type relays.
