10 SWITCH STATUS AND CONTROL
All P14x products support Switch Status and Control for up to 8 switchgear elements. This is available for
IEC60870-5-103 and IEC61850 protocols. The device is able to monitor the status of and contr
ol up to eight
switches. The types of switch that can be controlled are:
● Load Break switch
● Disconnector
● Earthing Switch
● High Speed Earthing Switch
Consider the following feeder bay:
V01241
XSWI1 XSWI2
XS
WI3
XSWI4
XCBR
Le
gend:
XSWI1 = Disconnector 1
XSWI2 = Disconnector 2
XSWI3 = Disconnector 3
XSWI4 = Earthing Switch
XCBR = Circuit Breaker
Figure 171: Representation of typical feeder bay
This bay shows four switches of the type LN XSWI and one cir
cuit breaker of type LN XCBR. In this example, the
switches XSWI1 – XSWI3 are disconnectors and XCSWI4 is an earthing switch.
For the device to be able to control the switches, the switches must provide auxiliary contacts to indicate the
switch status. For convenience, the device settings refer to the auxiliary contacts as 52A and 52B, even though
they are not circuit breakers.
There are eight sets of settings in the SWITCH CONTROL column, which allow you to set up the Switch control, one
set for each switch. These settings are as follows:
SWITCH1 Type
This setting defines the type of switch. It can be a load breaking switch, a disconnector, an earthing switch or a
high speed earthing switch.
SWI1 Status Inpt
This setting defines the type of auxiliary contacts that will be used for the control logic. For convenience, the device
settings refer to the auxiliary contacts as 52A and 52B, even though they are not circuit breakers. "A" contacts
match the status of the primary contacts, whilst "B" contacts are of the opposite polarity.
SWI1 Control by
This setting determines how the switch is to be controlled. This can be Local (using the device directly) remote
(using a communications link), or both.
SWI1Trip/Close
This is a command t o directly trip or close the switch.
