Transformer Monitoring via 4G LTE/3G



To safeguard and continuously improve the operational quality of electrical distribution networks, power customers are increasing their efforts to monitor every device on the distribution network. As a critical component of any smart-grid deployment, substation monitoring is key to these efforts.

In order to observe the power consumption status of distribution end-use sectors, power utilities hope to obtain real-time monitoring data from substations. This data is vital for analyzing the operational status of end-users and to detect potential problems, which may shorten outage duration, thus improving the power supply quality.

InHand Networks has over ten years of experiences in building wireless communication networks. For widely scattered distribution automation systems, InHand creates fast and easy to use 4G LTE and 3G network routers designed for real-time monitoring of substation performance, including GOOSE, DNP3, SMS and Modbus.

InHand Solution




InRouter900 grid router achieves instant substation monitoring.

● Dual WAN links, 4G/LTE, 3G/HSPA+

● 5*100M ETH Ports, 2*Serial Ports

● GRE, L2TP, IPSec, DMVPN and OpenVPN

● Data Acquisition and Storage

The InRouter900 series are the next evolution of InHand Networks’ trusted InRouter series. By integrating an embedded 4G LTE or 3G communication module and data acquisition solutions, the IR900 help customers avoid incurring additional cost for telemetry software and hardware. With InHand’s device cloud, the Device Network Platform, the InRouter900 will transmit operational data from the substation to the cloud monitoring center to achieve instant substation monitoring for thousands of devices spread over the grid.

The InRouter900 also supports email and SMS alarms, so that when a malfunction occurs in a substation, the IR900 will quickly generate an alarm message and transmit it to operations staff by email or SMS. Real-time online awareness allows technicians to shorten outage durations, prevent events such as rolling blackouts, and minimize impacts to the quality of consumer power distribution.



● The 4G LTE or 3G InRouter900 delivers real benefits to power customers:

● Upgraded power supply efficiency and shortened outage durations,Less operations support costs with a central cloud platform,

● Rapidly repair any malfunction with alarm functionality,

● Quick responses to unexpected problems.

The InHand solution for substation monitoring is designed for scalable, quick deployments with no downtime, ensuring positive budgetary performance. Substations become intelligent, allowing customers to detect and solve potential problems in the distribution network quickly and efficiently. With the embedded data acquisition and local alarm functions in the InRouter900, customers can enjoy real-time monitoring of the substations with upgraded fault response efficiency and reduced on-site support.
