Installing the TSU-25
Before powering the TSU-25, connect the antenna to the connector located on the front
panel.
The GPS antenna needs to be located with a good clear 360 degree view of the sky.
The ideal location for the antenna is a roof-top. However, in practice the TSU-25 antenna
All events in a substation can be precisely time tagged by the use of
GPS Time Synchronization Unit, TSU-25.
The TSU25 utilizes the accurate time signal broadcasts from the GPS
satellite network.
The TSU-25 has an integrated GPS receiver that constantly tracks up to
8 satellites simultaneously to provide a highly accurate time reference.
A software clock on the RTU-30t card will be calibrated every minute to
time-stamp events that occur in the digital and analog inputs. The time
information will be sent together with the alarm/message to the
SCADA.
Up to 7 RTU-30t cards can be calibrated from one TSU-25.
The RTU-30t has the same functions and I/O package as RTU-30 and
RTU-30i.
