In the electric power distribution network, a recloser is a circuit breaker that can be closed automatically after it has opened due to an electrical fault. It is common to find reclosers in overhead transmission/distribution lines to clear commonly occurring electrical faults. Thus, a recloser is able to restore the power automatically to the line without human intervention.
The status of the reclosers is critical to utility companies. In large country like Vietnam, there are thousands of reclosers installed throughout the country, many of which are found in rural areas. Maintenance engineers have to travel hundreds of kilometres periodically to check the status of individual reclosers.
The utility company in Vietnam had rolled out a project to upgrade their control system to centralize the monitoring of the recloser in a common location so as to reduce manpower cost and time as well as to improve productivity and efficiency. We recognized that laying hundreds of kilometres of copper or fibre optics cables to gather all the information from the various installed reclosers will cost a lot of time and money. The best solution to this problem: wireless applications. There are several wireless solutions available in the industry; however, using mobile connection is the only solution due to the large territorial distances and areas. We decided to propose our new TC Router.
We presented and tested our TC Router with the system integrator highlighting the following points:
- Extended temperature range, -40 °C to +70 °C (Ensures reliable operation even in the most extreme temperatures)
- VPN connection and integrated firewall (Ensures secure connection)
- Fallback to 2G (Ensures reliable connection)
Our customer was very pleased with our solution and had gained approval from the end user. Subsequently, we were awarded with the first batch of orders for 100 units of TC Router. Beside the energy industry, our TC Router can also be implemented in other industries such as Process, Water and Waste Water treatment as well.
