Generator protection REG670
Version 2.2
GPS time synchronization module GTM
This module includes a GPS receiver used for time
synchronization. The GTM has one SMA contact for
connection to an antenna. It also includes an optical PPS
ST-connector output.
IRIG-B Time synchronizing module
The IRIG-B time synchronizing module is used for
accurate time synchronizing of the IED from a station
clock.
The Pulse Per Second (PPS) input is supported.
Electrical (BNC) and optical connection (ST) for 0XX and
12X IRIG-B support.
Transformer input module TRM
The transformer input module is used to galvanically
separate and adapt the secondary currents and voltages
generated by the measuring transformers. The module
has twelve inputs in different combinations of currents
and voltage inputs. Either protection class or metering
class CT inputs are available.
Ring lug or compression type connectors can be
ordered.
High impedance resistor unit
The high impedance resistor unit, with resistors for
pick-up value setting and a voltage dependent resistor,
is available in a single phase unit and a three phase unit.
Both are mounted on a 1/1 19 inch apparatus plate with
compression type terminals.
