Abstract (en)
[origin: EP0054402A2] An alternating current generator for use as a shot exploder suitable for firing electric detonators coupled through toroid transformers e.g. 'Magnadet' detonators. The detonating system is energised by means of a signal that is automatically generated at the resonant frequency, thus avoiding the usual time-consuming and dangerous practice involving in-situ determination of inductance and selection of capacitors.
