How Do Current Transformers Sense the Current Direction In AC systems?
- 05 May, 2023
- Posted by: Daniel Rehe
You need a voltage reference to determine direction of current flow for AC sources.
Extending the leads on Rogowski Coils
- 05 May, 2023
- Posted by: Daniel Rehe
To extend the leads in Rogowski Coils, the main point is that you can extend the leads from the Coil to the integrator however you can not extend the leads from the Integrator to the meter. This applies to 1 Amp/5 Amp/ 0.333V Output Coils.
