- Output accuracy: ± 1% of the regulated value ± 0.1% of the full scale, with load of 25% to 100%.
- Gradient accuracy: ± 1% of the nominal, with a minimum of ±200 mV/s.
- Self protected in case of an overload greater than 100 W.
4.5 IEC61850 option; code PII80156
The IEC61850 Interface option for DRTS3 PLUS allows relay testing with Ethernet-based
substation communication protocol. The option, and the associated software, provides the following
features:
.
Capability of monitoring the Goose List and the Goose details of the messages transmitted by the
relay under test. The grid displays for each Goose:
•
Source Mac Address: physical address of the generator of the message
•
Destination Mac Address: physical address of the destination of the message
•
Goose ID: Identifier of the Message
•
Data Set Reference: Identifier of the type of message created by the IED
•
Event Time Stamp: Universal Time that identifies the Goose
. Capability of filtering Gooses, based upon IED or TIMESTAMP;
. During the test, trip commands are connected from the relay to the test set. In addition to this, the
option allows to define up to 8 Virtual Contacts, i.e. Gooses that will be captured in real time: the
test set will measure and display the corresponding timing from test start. A virtual contact is
identified by a:
•
Name: it can be given by the user by editing the relative box in the grid. The same name will
appear in the lower frame that represent the Trip condition for the Virtual contact.
•
Dataset Reference: it represents the exact goose that serves as the basis for the virtual
contact. The same device can and does produce more than one Goose ID, so in order to set
the virtual contact it is not enough to define the Goose ID, but the selection has to be made
on the Dataset Reference.
•
Type: it can be Boolean, BitString, Unsigned, Signed, Float or UTCTime.
•
Condition: depending on the type of the data it can be: Equal to, Less than, Greater than or
Not Equal to. It is set by default to Equal to, but it can be changed according to the data
type. Select the appropriate condition form the menu that appears when clicking on the
condition column.
•
Value: together with the condition field, it defines the actual condition of the Virtual
Contact. In case of data type Boolean, it can only assume value True or False.
•
Time: represents the actual ‘trip time’ of the virtual contact, or the time interpreted from the
goose that the device produces when the condition is verified. It cannot be modified, it is
automatically set by the software when a test is performed and a virtual contact has tripped.
The Ethernet connector type RJ-45 for the IEC61850 Interface is mounted directly on the front
panel of the DRTS3 plus. The option is to be specified at order. NOTE: with this option, if the
booster is present the serial interface is not available.
