VAMP40 relay – reading existing configuration and settings
VAMP40 relay is used mainly for feeders, motors, midlle voltage power transformers and capacitor banks protection. Relay has FBD logic (but in most cases you don‘t need FBD logic for simple scheme of feeders). Existing protection functions: current protections, undervoltage/overvoltage protections. First generation of relay VAMP40 was produced by company VAMP from Finland. Some couple […]
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 […]
Analyser Chauvin Arnoux CA8335: 3. Inrush mode
Inrush currents of motors, power transformer, capacitor banks can be measured using Chauvin Arnoux CA8335 analyser. In this article will be described measuring inrush current of motor. The same measuring principles fits to power transformer and capacitor bank. How to connect currents leads read article “Analyser Chauvin Arnoux CA8335 – 1. Transient mode” (particles 1 and 2). […]
Analyser Chauvin Arnoux CA8335: 2. Measuring harmonics
Analyser Chauvin Arnoux C.A 8335 can measure harmonics of electrical network. In previous article was described how to measure transients in power grid by using Analyser Chauvin Arnoux C.A 8335. The sequence of measuring harmonics: Powering of analyser. Connecting voltage and current leads. Setting of measurement scheme. Setting of measurement method. Setting of date […]
Analyser Chauvin Arnoux CA8335: 1. Transient mode
Hello, again! I‘m going to write several articles about power grid analyser Chauvin Arnoux CA8335. As usual manufacturer‘s manuals are unpractical. Chauvin Arnoux CA 8335 is portable power grid analyser. Analyser is very convenient, you can easy connect it to PC. Manufacturer’s page: http://www.chauvin-arnoux.com/en/produit/c-a-8335.html This analyser has several functions: Instantaneous measurements and vectorial […]
CAP505 course of PLC REF543: 28. Reading existing configuration from PLC REF543
At some cases you need to edit the existing configuration. But what if you don‘t have the required configuration file. In this article I‘m going to describe how to read the existing configuration from PLC REF543. Here I‘ll describe how to read existing configuration of incoming cubicle (IC-1). Reading basic principles of existing configuration: 1. […]
CAP505 course of PLC REF543: 27. Configuration of IEC60870-5-103 protocol
It‘s time to show how to configure IEC60870-5-103 protocol for PLC REF543. Signals are transmitting via this protocol from PLC REF543 to remote terminal unit (RTU). I‘ll show how to configure this protocol for PLC REF543 of incoming cubicle IC-1. PLC REF543 can also work with others protocols: Modbus, DNP3.0 and others. The configuration of […]
CAP505 course of PLC REF543: 26. Substation automation – incoming cubicle and testing procedure of automatic transfer scheme (ATS)
The configuration of incoming cubicle IC-1 and testing procedure are described in articles no.1÷22. In this article we are going to configure ATS scheme of IC-1. Basic principles of ATS you can explore in chapter no. 23 „CAP505: Substation automation – basic principles“. 1. Fundamental scheme of ATS: 2. Run „Relay configuration tool“ application: 3.The […]
