Gap Transmitter Calculator
GapTxCalc was developed to model the performance of the Gap
GeoPak high current transmitters for various loop configurations. The
program has proven to be invaluable for optimising loop design and wire
selection. Perhaps more importantly, it is also a useful reference
when selecting safe operating parameters by providing improved awareness of the
current carrying limitations of various wire sizes as well as relevant
voltage considerations.
In the interest of improving electrical safety within the
exploration industry, we are making the software freely available to other
geophysicists, operators and interested parties. Consequently, we have now
incorporated a range of commonly available transmitters for wider use and
comparison.
We are keen to improve the software for ourselves and others
and we welcome any feedback or suggestions. We will also consider adding
other transmitters as information becomes available to us.
Features
- Handles EM and Galvanic loops
- Calculates the loop resistance and inductance given the loop dimensions, number of turns, ground resistance, wire size and temperature
- User can select from list of predefined wire sizes or enter an arbitrary size within range
- Takes account of the wire current carrying capacity
- Calculates the maximum current and voltage for specified loop resistance
- Option to compare different geophysical transmitters
- Calculates the magnetic dipole moment and primary field at centre of loop for EM loops
