Sparkers
Geo-Source Triple 800
Maintenance free negative discharge and tunable frequency sparker specially designed for water depths up to 10,000 m.
Description
INNOVATIVE PRESERVING ELECTRODE MODE
The Geo-Source Triple 800 is designed for operation with the Geo-Spark 48kJ Pulsed Power Supply using the “Preserving Electrode Mode”. This patented concept consists of using a NEGATIVE electric discharge pulse, instead of a positive electric discharge pulse.
Note that working with a negative pulse is NOT the same thing as reversing the polarity of an antique power supply, which is generating a positive pulse.
OPTIMUM ACOUSTIC REPEATABILITY
Zero tip wear is essential for the repeatability of the acoustic pulse, which depends largely on a constant, unaltered electrode surface.
DETACHABLE SOURCE
The Geo-Source Triple 800 has the capability of detaching the source from the surface buoys, which makes possible to shoot with up to 5 m depth, providing more weather resilience and possibiities for achieving a desired pulse shape and enhancing the low frequency content of the spectrum.
FROM SHELF TO OCEAN DEPTH
The Geo-Source Triple 800 has proven results of 1000 m penetration with with 0.5 m resolution in the first layers.
REVOLUTIONARY PULSE SHAPING
The revolutionary pulse shaping technology allows full control of the wavelet and frequency spectrum.
HIGH VOLTAGE / POWER CABLES
The Geo-Source Triple 800 is towed a very high quality, Kevlar-reinforced, coaxial power / tow cable, with a stainless steel Kellum towing grip. This very sturdy, special HV cable contains 8 x 10 mm2 inner leads (negative) plus a 80 mm2 outer braiding (ground). It is designed to have a very low self-inductance in order to preserve the high dI/dt pulse output of the Geo-Spark 48kJ.
The wet side of the cable is terminated with eight special HV connectors to the electrode modules and a ground connector to the frame of the sparker.
COAXIAL CABLE = 100 % SAFETY + ZERO ELECTRIC INTERFERENCE
The coaxial structure of the HV power cable provides 100 % safety and reduces all electromagnetic interference to the absolute minimum.
HIGH VOLTAGE CABLE POWER WINCH + ROTATING HIGH VOLTAGE CONTACTS
The power winch with remote control and variable speed allows easy and safe deployment of the sparker source. The two axial HV connectors enables the operation of the winch without disconnecting the deck lead. Using the patch panel you can connect or disconnect the electrode modules without recovering the source to deck.
