<p>Current data are an important input data for electrical
prospecting data postprocessing. The existing current recorder is
inadequate for continuous recording, precision, bandwidth, dynamic range,
and input range. A new full waveform current recorder that is ideal for
measuring current signal for electrical prospecting applications is
presented. The new measurement principle enables the fabrication of a
high-precision current sensor with an autonomous data logger as well as
continuous measurement capabilities for full waveforms that are comparable
to recent developments for electrical prospecting applications. The full
waveform current recorder is capable of measuring current with bandwidth
from direct current (DC) to 10 kHz, with a power spectrum density noise floor of
10 <span class="inline-formula">µ</span>A/rt(Hz) at 10 Hz. The current recorder has a dynamic range that is higher
than 97 dB over a range of 100 A at peak, with time synchronisation error as
low as <span class="inline-formula">±0.1</span> <span class="inline-formula">µs</span>. These features make new current recorder a
promising technology for high-precision measurement with long-duration,
autonomous data logging for field electrical prospecting applications.</p> |
