where to buy clamp on ct 5/5a

We're using ION7650 meter as a power quality tool to do energy audit.

Sometime due to the big size of power cable (of incoming panel) which its diameter rather bigger than our clamp on CT (2000/5A), and this incoming panel had CT (2000/5A) already for customer's metering purpose. So, we're going to use our clamp on CT to measure the current at the secondary side (5A) of existing CT, by this way, we should use the clamp on CT with small ratio as much as possible, example 5/5A, 10/5A...

Does anyone know where to buy small ratio clamp on CT as mentioned?

Just a thought: why do use tie your ION meter to the exsiting CTs, as long as there is a CT shorting block u can accessan u can do this without a shutdown. The customer's existing meter should continue to work as normal when u wire these two in serial.

Thanks.
