High Power DC Electrical Measuring System, Type DJF20-1

DFF20-1 high power DC electrical measuring system consists of a rectification power supply (10 kw or 20kw), a 20kw generator, one or multiple (3~5) receivers, stimulators, dummy loads, AB electrodes, AB power lines, reels, measure electrodes and other accessories. DFF20-1 high power DC electrical measuring systems are widely used for metal and nonmetal mineral resource survey, high-precision mineral resource survey and the exploration of underground water resources.

• There are three synchronization mechanisms to ensure accuracy, including GPS, pulse delay and high accuracy quartz clock.
• The transmitter and rectification power supply are separated, so that the system is more portable and convenient for field work.
• The system is controlled by microcomputer and equipped with a large LCD screen and a touch panel, providing convenience to operators.
• Real-time storage of power supply current and sampling at every minute provide convenience for accurate calculation of apparent resistivity.
• There is overvoltage, overcurrent and overheat protection.
• The special small transformer is efficient and light-weighted.
