Classification: CPC F | IPC F

Claim 0:
1. A detonator installation including control equipment, the control equipment comprising:
a controller;
a voltage source, an inductor and a switch connected in series with the voltage source;
output terminals; and
at least one detonator including a capacitor and at least one protective diode, the capacitor and the at least one protective diode being connected in series to the output terminals;
wherein the controller is operable repeatedly to close the switch, thereby to direct current from the voltage source through the inductor which then establishes a magnetic field, and to open the switch so that the magnetic field collapses and generates a current which flows via the output terminals through the capacitor and the diode thereby to charge the capacitor.
