1.

The operating characteristics shown here are intended as an aid to prelimi-

nary gap selection. The characteristics listed are typical for the indicated

types under standard environmental conditions. The conditions found in

many applications will influence gap operating characteristics; therefore,

some characteristics may not be simultaneously achievable. Prospective

users of these gaps should be aware of the limitations in the data being pre-

sented. Contact PerkinElmer for information concerning the performance to

be expected in the intended application.

2.

SBV is the Static (Self) Breakdown Voltage. It is the dc voltage across the

main gap (between the opposite and adjacent electrodes, O-A) above which

the gap is likely to break down (conduct) with no trigger applied.

3.

The peak current applies for a critically damped discharge. Current reversals

degrade life, so gap operation in the underdamped condition should be

avoided when possible.

4.

In underdamped circuits, each current half-cycle contributes to the total con-

ducted charge, i.e., conducted charge increases independently of the direc-

tion of gap current. Therefore, the total conducted charge, including any “fol-

low-through” current, should not exceed the maximum conducted charge

indicated.

5.

Includes an internal shield to slow deposits of discharge debris on the insu-

lating ceramic.

6.

A small amount of metallic mercury is used in these gaps to aid in the forma-

tion of the initial discharge. These gaps should not be operated above 50°C.

Care should be exercised in the handling and disposal of these gaps.

7.

Proper application of these gaps may require them to be immersed in insulat-

ing oil or gas depending on the operating voltage level and environmental

factors. A method to circumvent electrical breakdown across the outside sur-

faces of the ceramic insulators of the gap may be necessitated in some

uses. Some of the more important factors to consider in determining the

insulation qualities of the environment are altitude (local atmospheric

pressure); humidity; dust; cleanliness; temperature and pulsed versus

dc operation.
