ChallengeThe electrical engineering professionals from Klebs+Hartmann GmbH & Co. KG are always at the forefront of technical trends – and that is why they rely on the latest technical solutions also in their own operations. Thus they can gather practical experience with new systems and also benefit from them in very tangible ways. And not least, the systems serve as demonstration objects for interested customers. At Klebs+Hartmann, as well as on the customer side, the major focus is on sustainability and energy efficiency. All relevant systems and solutions have been successfully deployed and need to undergo continuous further development at Klebs+Hartmann.
The company already implemented power monitoring according to ISO 50001 in 2012. For this purpose, the existing SIVACON S8 main power distribution was supplemented by relevant measuring devices from the SENTRON portfolio as part of an enhancement designed to make electrical and other energy flows transparent. The data are recorded by the measuring devices either directly via the current and voltage input or indirectly via additional sensors such as flow meters with pulse output (e.g. compressed air) and fed into the computer network through digital inputs (S0 impulses) from the 7KM PAC4200 measuring device via Modbus TCP. In addition the latest 3VA molded case circuit breaker generation has been added to the power monitoring system. The communication-capable models in the 3VA2 series come with an integrated metering function for the detection of current, voltage, and power values.
