1 Whats new in the CTA Software Version 4.30?

1.1 Support of the NEW IEC Standard for Current Transformers IEC 61869-2

The new CT Analyzer software version enables the test of current transformers according to the new IEC 61869-2 standard. The new standard can be selected in the GUI on the CT-Object card. Simply move down in the menu to the Standard selection field and choose the desired standard from the pre-configured menu via the soft keys. If preferred, the IEC 61869-2 can also be configured as default start-up setting.

The newly released IEC Standard for Current Transformers IEC 61869-2 replaces the former IEC 60044-1 and IEC 60044-6 standards. The CT Analyzer still supports the old IEC standards 60044-1 and 60044-6 additionally to the new standard to enable the test of equipment designed according to the old standard. A short summary of the main changes regarding the CT Analyzer measurement and assessment process can be found in the Customer Area on the OMICRON website. For more detailed information please consult the standard document available on the IEC website.

2 Whats new in the CTA Hardware?

2.1 PC connection via USB interface

CT Analyzer devices as of serial number JHxxxx or newer are equipped with a USB interface and a RS232 interface. If available, you can use both interfaces alternatively to connect the CT Analyzer to a computer. OMICRON recommends to use the USB interface since communication via USB is considerably faster than communication via RS232.

Since in this case the CT Analyzer provides two alternative interfaces, the user has to select the interface to be used (or check the selection) in the CT Analyzer settings before connecting the CT Analyzer. The factory default setting for those devices is USB.

4. Open the Main Menu on the CT Analyzer and select Settings.

5. In the Setting Menu page, select Remote Interface.

6. In the Select remote interface port page, select the interface actually used to connect the CT Analyzer to the computer: USB or RS232.

Note: The CT Analyzer will only communicate via the selected interface. It will not be recognized by the computer if the CT Analyzer settings do not match the interface used for connection. The following figures show the possible scenarios for connecting the CT Analyzer and the CT SB2 switch box to a computer.
