Efficient services of SPDs
“Our customers appreciate this solution with well-proven products, because the status messages of the devices will be transmitted and documented automatically what minimises the effort. Moreover, all relevant data will be visualised clearly on a dashboard.“

Adeded value for DEHN & SÖHNE
Because of the fast propagation and interconnection of electronic devices, a reliable protection against the effects of lightning discharges and grid-related overvoltages become more and more important – especially to prevent the often massive subsequent damages.
If a surge protection device (SPD) is overloaded because of a series of high-energy dissipation processes, this will be signalled by an integrated function and defect indication or potential-free remote messaging contacts for example.
A manual maintenance at the site was mostly necessary so far for checking the functional capability.
The explicit objective of DEHN+SÖHNE is a modern predictive maintenance concept for customers of the energy, data and information technology.
Because of lacking personal resources or widely distributed stations, it took quite a few days or weeks until customers checked their surge protection devices and replaced defective ones so far. During this time, there was the pending risk that the plant and operational reliability was not ensured any more!
In future, the customers shall be informed about the function status or defect message of their SPDs immediately, so that they can arrange for the exchange as fast and efficient as possible.
DEHN+SÖHNE has realised a common, proofed concept for condition monitoring and predictive maintenance together with their technology partner INSYS icom.
The messaging system integrated in the IoT gateway (icom Data Suite) performs the customer-specific data transmission to a cloud (i.a. MQTT, HTTPS), to a control center (also IEC 60870-5-104) and to an e-mail or SMS recipient or stores and visualises the data locally.
“Our customers appreciate this solution with well-proven products, because the status messages of the devices will be transmitted and documented automatically what minimises the effort. Moreover, all relevant data will be visualised clearly on a dashboard.
This provides even five benefits: 1. The provision of the spare devices is much easier, 2. the services are easier to plan, 3. the costs for the service are reduced, 4. all stations will be maintained in time and 5. the risk for damage to persons and property will be reduced significantly.“
