SERTEL ELECTRONICS (PVT)LTD COMPANY PROFILE
Dear Customer,
GPS Based time synchronization for various equipments of electrical / Instrumentation
and computers.
Ref: - Power generation / Distribution
With reference to the above we are glad to inform you and also introduce ourselves that we are the
manufacturers of time synchronization with an accuracy of 1 micro sec for time stamping. This time
stamping will facilitate to identify the problem First caused / trip to another where by all contactors /
Relays connected to cascading operation
.
The salient features of the Synchronisation system which is as following:
Master Clock and Slave Clock
•
Synchronised to GPS receiver (through satellite)
•
The slave clock can be connected to entire factory at various locations displaying the same
•
time through out the factory in terms of hour min & Sec.
Time Synchronisation
a) Electrical equipments Synchronisation
Time synchronization synchronizing the electrical parameters such as event recorder, disturbance
recorder, fault recorder and sequential event recorder. PLC’s, data acquisition system and other
intelligence or RTU (remote terminal unit).
b) Instrumentation Synchronisation
Intelligence instrumentation PLC’S, DC’S, DAS, SCADA and other intelligence RTU’S
c) Networking of Computers
Various computers connected through landline with Ethernet synchronization by TCP/IP with 10 base T
or 100 base T with RJ 45 connector connected to the hub. We have also developed NTP server, NTP &
SNTP broadcast, NTP client to synchronies many computers.
We can give time synchronization output for various above equipment requirement with any
number of outputs such as Pulse, Potential free contact, IRIGB, RS232, RS485, BCD output also
IPPS, IPPM, IPPH and for computers TCP/IP, network time protocol synchronization with any
distance by using appropriate access such as line drivers, line receiver and also convectors
RS485/232 convertor for synchronization of time with an accuracy for 1 micro sec.
