Teleprotection: Safeguarding the electrical grid
Critical to grid operations is the protection of power lines, through teleprotection.
Teleprotection systems were developed alongside the electrical grids themselves,
and the operational communication networks used are mainly driven by those applications.
In 1940. the average telephone user was just getting to grips with the rotary-dial telephone,
while Hitachi Energy was deploying power-line communications: utilizing the electrical
transmission infrastructure to carry teleprotection data and avoiding the need for a separate Pilot Line.
Public telecom networks have evolved at an amazing speed, this has been primarily driven
by new applications (e.g. smartphones, YouTube, email) which results in a growing demand
for increased bandwidth. Subsequently this has resulted in network solutions with a higher
capacity for data transmission with a lower focus upon the quality of service.

Teleprotection systems, in contrast, have always operated under the pressure of protecting
critical infrastructure. Reliability and quality of service is paramount, resilience is required,
while new technologies and techniques must prove themselves robust enough to match,
or exceed, the existing equipment before they can safely be used in the electrical network.
The fully redundant network element supports all SDH-traffic protection schemes
including 2/4-fibre MS-Spring. All optical ports are XFP / SFP based.
Fully integrated and managed boosters / preamplifiers / equalizers enable highly
flexible and reliable long-haul connections, without the need for additional external
devices. The robust mechanical and EMC-design including the distributed power
supply concept of FOX515H are optimized to cope with harsh environments which
are typical for utility applications. The mechanical, electrical and EMC / safety
performance of FOX515H is fully type-tested by an independent, certified Swiss
Test-lab. Most interfaces are provided with multirate SFP/XFP cages enabling each
individual port to have a different configuration with a wide variety of optical
wave-lengths for WDM, connectors and available ranges.
FOX615 integrates teleprotection interfaces for distance as well as for differential
protection simultaneously within state-of-the-art SDH networks and MPLS-TP networks;
ensuring an easy and flexible way to migrate technology in a utility network.
With its latest IEC61850 interface the FOX615 also acts as a substation IED and
enables GOOSE based protection applications of digital substations.
Built on Hitachi Energy’s huge domain expertise, the utility-grade design of FOX615
is deployed in thousands of installations across the globe with guaranteed performance
including those with electromagnetically polluted environments and across a broad range
of temperatures.
