Overview
RuggedCom products have always met or exceeded a wide range of industry standards including IEC 61850 and
IEEE 1613 for electric utility applications. We have even designated a RuggedRated™ certification to promote the fact that all our products undergo extensive in-house testing to ensure they meet these rigorous industry standards. Based on our good reputation, domain expertise in the industry, and by having the world’s largest installed base of substation hardened communications equipment, customers have had the confidence to rely solely on our internal tests. But with so many vendors now claiming compliance, we at RuggedCom felt it necessary to obtain independent 3rd party test reports for some of the industry’s key standards. RuggedCom is the first in the industry to obtain such testing. This information flyer summarizes some of the key test results performed by KEMA, a worldwide authority on product testing, certification, and consulting to the electric utility industry.

Test Descriptions
VLAN Handling
Verify the multicasting of VLAN tagged IEC 61850 GOOSE messages. All VLAN tests performed PASSED.
Priority Tagging
Verify that higher priority messages will prevail over lower priority messages. The expectation is that on a network with mixed priority packages, no high priority packages will be dropped. All priority tagging tests PASSED.
Rapid Spanning Tree Performance
Verify the recovery of a single communication failure and to measure the recovery time and the number of packet drops.
This may depend on: Packet size, Network load; Connecting / Disconnecting the backbone ring. GOOSE messages are sent
on a 1 millisecond period with the backbone ring disconnected / connected at multiple locations.
- Based on the test results it was concluded that:
- During a communication failure no GOOSE messages are lost
- Disconnecting and connecting the backbone ring has no effect on message loss
- The network load has an effect on recovery time
- The size of the GOOSE messages has little effect on recovery time
RuggedCom uses the following formulas to calculate the Worst Case Recovery Time and the Typical Case Recovery Time
(where N is the number of switches):
- Worst Case Recovery Time = 20ms + ( 5 * N )
- Typical Case Recovery Time = 5ms * N
During the tests, the recovery time was found to be much less than the Typical Case Recovery Time.
