marks of the Line potential device and selecting the “polarity mark” voltage with jumper P12.
That is, if the Line voltage is

V

AB

, set jumper P12 for the

V

a

 position. Selection of the Bus voltage

reference described assumes phase rotation ABC. If the phase rotation is ACB, the Bus voltage
reference would be

 V

b

. Synchronism voltage input reference to “Line” voltage and “Bus” voltage

can changed using the Synch Volt setting. For example, if the Synchronism Voltage input is from
what would be referred to as the “Bus”, the Synch Volt setting could be changed for correct LED,
LCD and targeting displays

The 120 volt, phase to phase synchronism voltage option (i. e. REL 301/302 style number, digit
6 is a T) corrects for the 30

o

phase shift difference between line to neutral protection voltage in-

put and line to line synchronism voltage input. Components have been added to hardwire the
phase shift compensation.   Hence when viewing the

“Bus-Line Angle”

 on the Man-Machine

Interface (MMI) display, synchronism is represented by 0

o

 angular difference between Bus and

Line voltages, not -30

o

.

If voltage checking (

HBDL

 or

HLDB

) is to used, either independently or with synchronism

checking, the setting of voltage threshold

“V Max”

 is with reference to a 50-120 volts scale. In

other words if

“V Max”

 (Live voltage) is desired to be 100 volts, set

“V Max”

 to

“100 Volts”

. The

same is true for

“V Min” with a range

 0-50 volts.

All other settings for operation of REL 301/302 reclosing are the same as the 70 Volt Synchro-
nism voltage relay.
