Section 1 GENERAL

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). The basic operation consists of a unit receiving a voltage from a closed contact (Trip input)

from a relay into the transmitting terminal and having it communicate to the receiving terminal, which

provides a closed contact and a externally sourced voltage output (Trip output).

FEATURES

DESIGN: The PTR-1500 has been optimized for high speed, high Dependability, and high Security. Single

and Dual Channel FSK modulation techniques are used in conjunction with digital differential Guard/Trip

energy sensing. These methods have a proven record of accomplishment for high reliability in the tone

protection relaying applications.

PROGRAMMABILITY: Operating characteristics of the PTR-1500 are controlled by firmware. The majority

of parameter changes are accomplished by changing DIP switch settings. A few logic changes are made

by PROM/EPROM replacement. Frequencies, channel bandwidths, communications protocols, and logic

modes are all programmable.

COMPATIBILTY: The PTR-1500 is compatible with other INIVEN PTR equipment as well as certain other

manufacturer’s audio tone protection equipment, depending on their configuration.

STABLE OPERATION: The Digital Signal Processing (DSP) technology used to generate the transmitter

frequency, establish receiver frequency discrimination, and manage all channel filtering, is crystal controlled.

This design provides a high level of stability, which overcomes the drift with temperature and age problem

encountered with analog methods.

LOGIC MODE OPTIONS

The PTR-1500 is designed as a four channel communications system that can operate in three different

modes depending on how the Logic module is programmed

1. DUAL CHANNEL – two frequencies are always generated by the Transmitter, either two Guard

tones or two Trip tones, one from Sub-Channel A and one from Sub-Channel B, from the selected

frequency Group (see Table 1-1) chosen by the customer. The Guard frequencies, one from each

Sub-Channel, are transmitted during normal, non-Trip, operation. When a Trip input is received by

the PTR-1500, the Transmitter will output both Trip frequencies, one from each Sub-Channel. The

PTR-1500 connected to the other end of the communication line will only allow a Trip output to the

receiving end’s relay when it has received both Trip signals simultaneously. The use of two frequencies

for Guard and Trip signals dramatically increases the Security (see Security charts later in this

section) of the system.

2. SINGLE CHANNEL – one frequency is generated by the Transmitter, either a Guard or Trip tone.

The frequencies will be either Sub-Channel A or B, but not both, of the selected frequency Group

(see Table 1-1) chosen by the customer. The Guard frequency is transmitted during normal, non-

Trip, operation. When a Trip input is received by the PTR-1500, the Transmitter will output the Trip

frequency and the PTR-1500 connected to the other end of the communication line will allow a Trip

output.

3. DUAL INDEPENDENT – two frequencies are generated by the Transmitter. The system operates

as two Single Channel units simultaneously. In this configuration, two separate Trip inputs are

received by the PTR-1500. Trip input 1 will be transmitted using a single frequency, Sub-Channel A

of a frequency Group (see Table 1-1) chosen by the customer. During normal, non-Trip, operation

the Transmitter will output the Sub-Channel A Guard tone. When a Trip input is received by the PTR-

1500 from Trip input 1, the Transmitter will output the Sub-Channel A Trip tone and the PTR-1500

connected to the other end of the communications line will allow a Trip 1 output. Trip input 2 will

cause the system to operate the Guard and Trip tones of Sub-Channel B in the same manner as

described for Trip input 1. Each Trip input will operate independently of the other.

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….

The PTR-1500 can also be ordered as a single direction or as the standard bi-direction. A single direction

unit can only transmit or receive while a bi-directional unit can do both. These options may also be combined

with the different logic configurations.
