Unlike conventional suppression techniques using metal oxide varistor (MOV), gas tube, or silicon diode technology, the GTT is the first suppression device approved by Underwriters Laboratories to go directly on the ground line of electronic equipment to prevent disruptions in operation.
The technology incorporates a patented circuit with no moving parts or sensitive electronics, and as a result, does not pose any threat to intrinsic safety ground, and is the first to be UL approved for use in grounding applications.
"No previous power protection technology addressed the unsolved problem of ground transients entering a system through the ground line", explains Dan Weaver, ECM.
"By eliminating transients on the ground, potentially damaging voltages have no means to enter equipment".
For years engineers have tried to put inductors on the ground line to eliminate ground transients, but suitable-rated inductors had too high resistance and were unable to cover a wide enough frequency range to be effective.
By combining newly developed core properties in this filter, the GTT solves these issues.
The GTT works by opposing changes in electron flow on the ground wire.
This slows the damaging rise and fall time of a transient voltage waveform rather than clipping it off, controlling frequency rather than amplitude.
The filter is designed to achieve sufficient attenuation in the frequency band that covers interference, and minimal attenuation at 50/60Hz, thus eliminating transient surges on the ground wire.
With GTT protection installed directly on the ground line, equipment becomes less susceptible to system crashes, lockups, loss of information, false alarms and other malfunctions.
This increased reliability leads to greater organisational productivity and ultimately an improved bottom line.
