This would apply to systems that use dual chan-
nels such as Direct Transfer Trip (DTT) or
Segregated Phase Comparison.
Following are the type of hybrids and their associ-
ated style numbers.

3.4.1 Examples

Following are several figures that illustrate possi-
ble hybrid applications. A short description of
each follows.
In these illustrations, Resistive Hybrids are denot-
ed as R hybrids, Reactive hybrids as X hybrids
and Skewed hybrids as S hybrids. Fig. 3–21 illus-
trates two transmitters being combined onto a sin-
gle coax cable for connection to a line tuner. This
would be a typical application for a dual channel,
uni-directional trip system. The receive end of the
system would not require a hybrid so that the
receivers would be tied together via coax cable
before connection into the line tuner.
When only one transmitter and one receiver are
required as in a single channel bi-directional trans-
fer trip system or a directional comparison
Hybrid Option
• Resistive Hybrid
• Resistive Hybrid (40W)
• Skewed Hybrid (50Ω)
with terminating resistor
• Skewed Hybrid (75Ω)
with terminating resistor
• Reactance Hybrid
• 19" panel suitable for 3 Hybrids
For more details, please refer to the Hybrids System manual.

unblocking system Fig. 3–22 can be applied. A
skewed hybrid may be used in place of the reac-
tive hybrid (X hybrid). The skewed hybrid has a
designated transmit port and receive port.
When two transmitters and two receivers are
being applied to a single coax cable, as in a dual
channel bi-directional direct transfer trip system,
Fig. 3–23 is appropriate.
Four transmitters used for similar applications can
be combined as shown in Fig. 3–24. This would
be representative of two dual channel uni-direc-
tional transfer trip systems. This provides equal
losses to each transmitter.
When different types of modulation and different
bandwidths are utilized, it is better to arrange the
transmitters and receivers as shown in Fig. 3–25.
This allocates loss based on performance factors
of the modulation type and bandwidth.
