CSC-196 Time synchronization device for power system Manual
1. General
1.1. Brief introduction of the device
The CSC-196 power system synchronous clock device (hereinafter as “the device” for short) is a
timing reference signal output device that is developed and produced by Beijing Sifang
Automation Co., Ltd. (hereinafter as “Sifang” for short) according to Specifications of time
synchronization system for power system for supplying accurate time synchronous signals to
equipments at substations and dispatching ends such as the PMU, protection, monitor, fault
oscillograph and so on.

1.2. Functions
1) It is designed according Specifications of time synchronization system for power system
strictly. Multi-type time synchronization systems such as the basic mode, master slave mode
and run-standby mode, the working logic and technical parameters of the clock comply with
the specifications, in addition, output signals can be expended freely.
2) Multi external time reference signals such as GPS, Beidou and IRIG-B (DC), up to 4 time
reference signals are available per clock, the signals are mutual redundant hot standby, with
excellent reliability.
3) The core time-transfer algorithm of the device is based on the patent 200410009685.2
(“Beidou No.1” navigation satellite system and GPS mutual standby time transfer method and
device), which may filtrate random error of input signal second punctual edge, when multi
input time signal is accessed, it can identify and follow the best input signal automatically and
