Influence of the current pulse shape to the measurement of electric detonators firing impulse

When determining firing impulse, electric current through detonator is measured. The current can be measured by measuring voltage drop over known resistance or by magnetic effects of electric current. Shape of current pulse influences the possi-bility to use transducer with magnetic effects. Rise time of pulse limits the possibil- ity to choose a recorder of appropriate bandwidth and necessary resolution. There-fore, the measurement system with possibility to create rectangular and sine shape was assembled, and measurements of firing impulse with both current pulse shapes were conducted on the same type of detonators.
