IEC 61850-3 Certified
The IEC 61850-3 and IEEE 1613 standards precisely define EMC and communication requirements for network equipment used in power substations. Substation computers and Ethernet switches must be IEC 61850-3/IEEE 1613 certified to guarantee adequate protection against a variety of environmental conditions. These minimum requirements include:
• Level 4 EMC, for strong protection against electrical interference.
• -40 to 75°C ambient temperature tolerance
• High tolerances for constant vibrations and shocks

Benefits of Moxa’s Integrated PRP/HSR Technology
• Fully compliant with latest international IEC 62439-3 standard for highest stability and interoperability
• PRP and HSR in a single box give you a choice for improving reliability
• 100/1000 Mbps across combination PRP/HSR/InterLink ports
• Supports hardware-based IEEE 1588v2 PTP
Zero Packet Loss at Wire Speed
The possibility of packet loss is even more likely in a high EMI environment than in more conventional settings, so ensuring critical packets are accurately and reliably transmitted is a key concern for any electricity supplier. Addressing the communications integrity challenge posed by high EMI environments, Moxa has two approaches and technologies:
Noise Guard™: Wire-Speed Zero Packet Loss Technology
| First, to meet IEEE 1613 Class l requirements network devices must have a level 4 EMC rating, to guarantee they will reliably tolerate high EMI conditions. • Mechanical Design: Integrated housing for better conduction • Customized Component: Newly redesigned fiber transceiver • Enhanced Power Supply Unit: Optimized circuit design, upgraded components |
 |
IEC 61850 QoS
Second, all devices must communicate critical, low-level IEC 61850 multicasts (GOOSE/SMV) with the highest priority, without fail. Prioritizing the transmission of GOOSE/SMV packets guarantees that these messages are clearly received without distortion throughout the entire network, regardless of what other communications may be currently congesting the lines. Ping-based solutions are not sufficient to achieve this. To fully satisfy IEEE 1613 Class 2 requirements, substation switches must support strong QoS traffic shaping.
| • Communications packets may be assigned different priorities, depending on their importance • Packet types: GOOSE, SMV, PTP • Packet priorities: High, medium, normal, low |

Fanless Design with Wide Temperature Tolerance
A broad temperature tolerance is required in any substation environment, where temperatures may run as high as 75°C or as low as -40°C. Most computers fail when faced with these extremes. The challenge electricity suppliers face is how to guarantee that their systems will continue to function reliably and predictably even when enduring the most extreme environmental challenges.
Patented Heat Dissipation
To endure harsh environments and ensure optimal operating performance even at high temperatures, Moxa introduced its patented L-type™ heat sink. The L-type™ heat sink is a heat dissipation mechanism that cools down the unit's internal temperature, and works by placing a plate in direct contact with the chief heat source inside the unit.
| • Maximize heat dissipation by keeping the sinks close to the heat source • Highly efficient heat pipe engineering • Stackable, for close-in rack use |

FloTHERM CFD Simulations for Heat Optimization
After many years of using FloTHERM to refine our development techniques, Moxa may now call upon a rich catalog of past methods, designs, and evaluated components when creating new devices. This database empowers our engineers with a wealth of component information, allowing them to easily evaluate a wide range of approaches for achieving specified thermal tolerances. By using FloTHERM’s advanced modeling techniques, our engineers may quickly and easily create virtual models of electronic equipment that allow them to effectively analyze the thermal limits of proposed modifications before any physical prototypes are built.
