Framework agreement hybrid gas density monitor with reference camber, switching contacts and modbus signal

Energinet has high-voltage (up to 400 kV) circuit breakers filled with gas SF6. To reduce the amount of leaked SF6, it has been requested that Energinet should be able to monitor leakages more closely making Energinet able to react faster than today. With this Framework Agreement Energinet wants to buy monitors which should be mounted on the breakers to be able to monitor the pressure in the breakers and transfer data back to Energinet. 1. Background Energinet, who is the Danish TSO (Transmission System Operator), has high-voltage circuit breakers filled with gas SF6 which is a very CO2 polluting gas variant. It has therefore been requested that Energinet should be able to monitor leakages more closely to react proactively instead of reactively. 2. Purpose Energinet wants to replace the existing gas density monitor with new Hybrid gas density monitor, which is capable to monitor the pressure in the breakers and thereby collect different data, and analyze the trend over time and identify SF6 leakages early in the process. The Hybrid Gas density monitor must be able to communicate with a communication node which is transferring the data via LoRaWAN to Energinet. 3. Scope of this tender The scope for this tender is to provide a framework agreement enabling Energinet to purchase Hybrid Gas density monitors with Modbus, for surveying our SF6 filled components. The SF6 sensor / Hybrid Gas density monitors with Modbus will be put into tender, but the recipient LoRaWAN gateway is Energinet's own responsibility and coverage meaning that the LoRaWAN standard becomes the dividing line between tender and Energinet and is not part of this tender. The tender will only be focusing on the delivered products; there will be no need for a maintenance agreement as Energinet aims to get a deploy and forget solution. We are currently looking into a demand for 2.400 units which need to be mounted on our AIS breakers. 4. Energinet's market knowledge Energinet currently uses products from TREFAG and WIKA. Through market knowledge Energinet believes that products such as TREFAG model 8791, or WIKA model GDM-100-T / GDM-RC-100-T or similar products can meet the requirements in the tender.
