's PTR-1000 is a high speed communications system for use in electric power transmission teleprotection schemes. The terminal is capable of transmitting and receiving up to 2 channels over any voice grade (500-3500Hz) communications path or point to point fiber optic.
The PTR-1000 uses DSP (digital signal processing) technology and is microprocessor controlled. Its FSK (frequency shift keyed) modulation techniques along with linear differential signal energy sensing allow for high speed tripping while providing a high degree of dependability in the presence of noise and greater security against false trips.
The PTR-1000 is on board programmable using DIP switches and proms and does not require any external programming devices.
There are thousands of PTR-1000's in the field and it is the standard unit at electric utilities around the world. It has proven to be an extremely reliable unit but if the need arises the system is covered by a 12 Year Warranty.
