GDD TRM supplies power for Pulse EM Surveys using the GDD 3600 watts I.P. transmitter

"GDD TRM for Pulse EM"

The use of the GDD time domain IP transmitter(s) with the GDD TRM
allows to work in IP frequency domain, time domain (adjustable timing) and Pulse EM for very large loops (field tested with a 16 km loop using small gage wire).

The GDD TRM uses the power of the GDD 3600 W I.P. transmitter to energize the loop.

The TRM module can drive 10 A, from 150 V to 2400 V (14 steps), with a peak power up to 3600 W. This system has been developed and used successfully for deep Pulse EM surveys by the largest Canadian producer of nickel in the Sudbury region. Also, if 2 GDD transmitters with 2 GDD TRM are used, it cand send up in the ground up to 4800V and 10A while synchronization is done by Geonic transmitter, Crone, Zonge. OEM, Smart5, or any other compatible transmitter

The GDD TRM is sturdy and can operate in extreme climatic conditions (­40 oC to 65 oC). The GDD TRM module can be hooked directly on a 240 V AC power source, such as a portable generator (e.g.: Honda or another model). As the loop can measure up to 16km, an "Open Loop" protection has been added to avoid any risk of electrocution.

Benefits from the use of the new GDD TRM for a 4 km surface loop in Sudbury

  • The higher voltage gaps (up to 7200W- 4800 V) allowed to send a higher current (up to 10A) resulting in drastic:
  • Better penetration
  • Higher signal to noise
  • Faster readings
  • New anomalies at greater depth
  • Lower costs for the client and bigger profits for the contractor
