New smart residual current monitor launched

16-05-2022 | Danisense | Test & Measurement

Danisense has released a ‘smart version’ of its versatile Residual Current Monitor (RCM). The new SRCMH070IB+ model provides an USB connection allowing residual currents to be analysed in detail through a PC using Windows software. As well as the oscilloscope function, an FFT analysis can also be performed.

The new SRCM model features scope for residual current; residual current FFT; TRMS in frequency ranges; remote setting of rated RC limit, frequency range and integration time; change settings from PC; and TRMS log, relay status log, data export. The auto setup will propose an appropriate frequency range and integration time

Ideal for monitoring the residual currents in production machinery or data centres with no need for fast system shutdown, the Type B/B+ SRCM device measures DC and AC residual currents up to 2Arms at frequencies up to 100kHz, making it ideal to a broad range of industrial applications, non-linear loads and generation sources such as renewable energies. Particularly, the product is compliant with the updated norm IEC62020-1. This indicates that it can employed for remote monitoring with no need to perform periodic onsite checks of the insulation resistance.

Comments Roland Buerger, business development engineer, at Danisense: “We can currently see that residual current monitors are no longer just coupled to the conventional energy measuring devices. In the future, the monitoring will be taken over by the PLC. The system-related leakage currents can thus be linked to the respective status of the plant. In this way, real fault currents can be detected much more accurately and reliably.”
