Geo-Spark 6 kW

CUTTING EDGE PULSED POWER TECHNOLOGY

The Geo-Spark 6 kW PPS is a revolutionary HV power supply based on cutting edge “pulsed power” technology. The system uses an extremely reliable, state-of-the-art discharge thyristor switch capable of generating short (200 - 300 μsec) HV pulses of up to 10 kA at -4.0 kV DC.

Each power supply has integrated external capacitor banks consisting of four indestructible capacitors, each of 32 μF, rated for more than 108 discharges.

NEGATIVE ELECTRIC DISCHARGE PULSE

There is no other unit commercially available that allows you to generate a negative high voltage pulse with such a high dI/dt ratio.

NO ELECTRICAL OSCILLATIONS

The pulse output has NO electrical oscillations, which affect the acoustic signature. The integrated capacitor banks contain 12 (6 kJ) or 32 (16 kJ) indestructible 32 μF capacitors rated for more than 200 million discharges.

QUALITY BUILT TO LAST

The pulsed power supplies are built to last, electronically and mechanically. The housing and frame consist of anodised aluminum and stainless steel 316. Rubber shock absorbers support all the vibration-sensitive components inside the housing.

All connections, command buttons, switches and status LEDs are front-mounted to ensure direct safe access and intuitive operation.

MODULAR ARCHITECTURE

The systems comprise four main types of modules, configured to customer’s needs:

• control unit, containing the thyristor stack and

• main control system;

• low voltage pulse unit;

• high voltage transformer/rectifier unit;

• 3 capacitor banks of 2x64 μF each.

TRIGGERING

Remote triggering of the unit is implemented by a TTL pulse, which is internally converted into a fibre-optic signal to the thyristor trigger device. There is no need for any external opto-isolator on the trigger line. During standby between survey lines, the unit will NOT trip - it will slowly bleed off but will remain ready for the next line.

LOW POWER CONSUMPTION

The Geo-Spark 6 kW systems can be operated from a 380 V/32 A mains socket or from a 380 V/10 kVA generator, and do not draw excessive peak currents.
