May we take a few minutes of your time to
introduce our company, products and services that we offer to electric
utilities, cable manufacturers/installers and consulting engineers in the
field of high voltage transmission/distribution systems.
Geotherm Inc., started out 28 years
ago in Canada offering test instruments and services for the measurement and
analysis of thermal parameters using state-of-the-art technology. These find
applications in numerous fields where the knowledge of heat and mass
transfer through natural as well as man-made materials is essential. The
soil is of particular importance in view of the modern trend in utilizing
the sub-surface for many purposes. Underground and submarine power
cables, storage and containment of radioactive spent fuel, and the
utilization of earth energy for space heating and cooling via ground-coupled
heat pumps are prime examples where this knowledge of soil thermal
properties is a must.
As a result of pioneering work performed for
the electrical industry in North America, Geotherm has developed test
and measurement instruments, and the technology whereby results of a high
degree of accuracy are obtained rapidly and economically. The practical
applications are limitless because the test equipment is portable and
ideally suited for field as well as laboratory use.
In addition to route thermal surveys,
laboratory testing and design of corrective thermal backfills for power
cable projects, we offer engineering and consultation services in the field
of distribution, overhead transmission as well as civil and construction
aspects of tower and sub-station foundations. We have over 200 route
thermal survey projects to our credit; including underground and submarine
crossings of record lengths. The South China Sea (Bakun - 640 km), Baltic
Sea (Sweden-Poland, 230 km), Australia - TransEnergie US (180 km HVDC
cable), Persian Gulf - U/G and submarine (60 km), NYPA - U/G and submarine
(50 km), NEES- submarine (80 km), KeySpan Construction (35km) are prime
examples.
We were part of the team of experts
retained to investigate the cable failures in Auckland, New Zealand.
