    Figure 1-1. PTR-1500 DESCRIPTION The PTR-1500 is a communications system used for the protection of electric power generation and distribution equipment. A protection system consists of two PTR-1500 units that communicate with each other via voice-grade telecommunication lines (i.e., carrier, wire line or metallic pairs, fiber optics, and microwave).

  • Page 9: Logic Mode Options

    Because the PTR-1500 is a four channel unit, it can operate 2 of the above logic schemes independently in the same unit. The 2 “halves” of the unit need not be the same. For example, a PTR-1500 can be ordered with 2 Dual Channels, a Dual Channel and a Single Channel, a Dual Independent and a Single Channel, etc….
