Loss of reading from Current/Power clamp meter

Hi, newbie… I have a clamp transfomer on my incoming power cable (live cable) so i can get the data/amps used by our house, but the readings sent to the Pi keeps droping out. Any ideas on the isseue and how to reapir it?
I am using a 4 channel ESP8266 mains/current SCT0130 board (100amp/50mA). And a Split Core Current Transformer 100amp SCT-013-000
