Current Transformer CSLT B100 from Honeywell

Submitted by Guest on Sun, 08/05/2011 - 05:38

Hi,

The australian project at smartenergygroups.com is using the Honeywell CSLT B100 Current Sensor http://sensing.honeywell.com/index.cfm/ci_id/140409/la_id/1/document/1/re_id/0 in their project.

Nevertheless it's tiny compared to the Efergy solution and that might be required in some cases.

Perhapse you can even refer to the smartenerygrgoups on your site.

Hi Kiwi,

It is indeed tiny! I am familiar with SmarterEnergy Groups. Trystan has exchanges some email with the Sam the man behind the project. The reason we have adopted the Efergy design is that its easy to clip round existing cables without disturbing them. If energy monitoring was to be integrated into circuits during the wiring off a house then the Honeywell sensor seems perfect.

The Honeywell CT will probably (I haven’t checked) have a different number of turns that the efergy CT. This will probable mean a different value burden resistor will need to be used.

Thanks for the link.

All the best, Glyn.

The Honeywell sensor isn't a current transformer, it's actually a Hall-effect transducer with a toroidal iron core around it. So it doesn't have a number of turns, and doesn't need a burden resistor.

Aha, thats interesting, thanks for clarifying.
