Single Phase 200A Electric Meter Burnt Out on 3-Phase 230V Supply, 30A Load

Hi ! I have a single phase electric meter  rated 200amp and the load is just 30amps max!. After several months of using it just burnt out for no reason

Note: We ensure that the terminals is tight and the meter base and the meter itself is brand new but after only several months it always burnt for no reason
 It is connected to a 3 phase  3 wire supply. with line to line voltage of 230v

idk guys if its because of fluctuation of electric provider or what.

Hi MarwinDo you have any info on the meter, brand, model etc?And your incoming supply voltage, you said that its 3 phase 3 wire, is that 115v phase to ground?And when you say burnt out, how exactly do you mean? What happens to the meter?

yes it is GE kv2c class 200 single phase meter. 

yeah 115v phase to ground but we're using line to line 230v 

burnt out .. I mean totally like the meter base and the meter are totally burnt. Given that all terminals and clip are tight and given that the load is just 30amps  I cant find any reason to prove why my meter always burnt.  I dont know man if it is due to the fluctation or something else i hope you can help me with this situation sir.

Do you have any details on the meter base?And what ratio CT's are used to connect to the meter?

Its just a self contained meter sir .and the meter base is just 200amp 5 jaws

A small meter like that is unlikely to be suitable for 200A or even 30Amps.  I would expect it to need to have CT's used in combination with it to bring the input current down to 1 or 5 amps. something like what is shown below.

idk sir because if my meter and meter based are rated 200amps  how come that my meter always burnt if I only have 30amps load max ... 

Hi Marwin,Do have have a photo of the nameplate or exact specification for the meter?

Something like this is what i ment.

Single-phase electricity meters are designed essentially to measure energy consumption and its quality factor as well as provide means to prevent tampering. Today’s smart meters can connect to a wide-area network (WAN) and the cloud through a data concentrator and a home area network together with in-home devices in addition to gas and water meters. This enables the automatic metering infrastructure (AMI) that helps utilities better manage customer services and encourage consumers to embrace energy-savvy behavior to optimize their costs.
