Analyser Chauvin Arnoux CA8335: 4.Trend mode

          In article no.3 „Analyser Chauvin Arnoux CA8335: 3. Inrush mode“ I‘ve described how to measure starting current of motor. However by using “inrush current” mode you can’t measure the whole time of starting motor. For this purpose more convenient is to use “trend mode”. By using “trend mode” you can also monitor parameters of […]

REF610 relay – reading existing configuration and settings

Relays REF610 designed by company ABB are used mainly for feeders protection. These relays don’t have FBD logic (for example PLCs REF541, REF543, REF545 use FBD logic) therefore their configurations are very simple. Standart relay REF610 has 2 binary inputs and 5 binary outputs (including 3 power outputs). This relay have also internal relay failure […]
