may be used for synchronization.

Sensor interface board with jumpers is shown in the figure 6.2a. Enlarged portions of the board are in the
figures  6.2  b  and  c.  Jumper  positions  as  they  are  shown  (default)  configure  external  reference  for  a
coupling  capacitor.  Arrows  show  default  position  of  the  jumpers.  In  this  case  power  frequency  signal
component  from  PD  channel  #1  is  brought  to  the  “Ref”  terminal  #8  and  may  be  used  for  both  external
synchronization and phase reference shift measurement.
In  order  to  use  “Ref”  terminal  for  an  external  signal,  the  jumpers  J1  and  J2  should  be  removed
disconnecting “Ref” from PD channel #1.

6.1.2 Revision 1

As  default,  jumpers  in  the  sensor  interface  board  are  configured  for  synchronization  from  power
frequency  signal  component  of  the  channel  #1.  This  assumes  that  coupling  capacitor  sensor  from  the
phase  A  is  connected  to  this  channel.  Therefore,  once  jumpers  in  IG  are  moved  to  external
synchronization  option,  as  it  described  in  6.1  (the  figure  6.1)  above,  IG  will  be  synchronized  from  PD
sensor  connected  to  the  channel  1.  Jumper  J1  actually  connects  this  input  to  synchronization  circuitry.
Refer to the figure 6.3 for jumper locations.
