Power Quality Current Sensors

[Twin1986]

Greetings

I work for Eskom Electricity Utility in South Africa. I am researching about harmonics measurement using Capacitive Voltage Transformers. Power Quality Current Sensors have been developed to improve the accuracy of harmonic measurement by CVT's in 132kV systems. I have the following questions in relation to the sensors:

1. What are the operational hurdles of the Power Quality Sensors

2. How much do the sensors cost

3. Where can these sensors be sourced


Your input is highly appreciated


Kind Regards
Thabiso

we have just started using a device called PQ sensor which monitors the current flowing through the primary connection of CVT.Please find attached brochure of the same
