Frequently Asked Question

• In this case, you should verify the device configuration.

Wrong configured Parameter	How detected	How to configure
Topology		According the network
Nominal frequency	DSP Sync : off, possibly misconfiguration error	According the network
CT/PT	Wrong current/Voltage readings	According the Transformer
Nominal Voltage	Not detected on the real time, only at recordings, therefore It is recommended to wait few minutes and download 1 file before leaving the site. Wrong nominal setting will cause wrong reference for all Compliance Voltage related parameters (include Power quality events such as Dip, Swell Interruptions..) In addition, the nominal influence the compression efficiency.	As the declared Nominal Voltage
Nominal Current	Not detected on the real time, only at recordings, therefore It is recommended to wait few minutes and download 1 file before leaving the site. Nominal current setting influence the compression efficiency therefore has influence on the data size and can also overload the CPU when set too low.	This parameter should be configure within the average Current range
I/V ratio (only when using custom Rogowski clamps)	Wrong Current readings	As defined on clamps. Remember that the device input accept up to 10V. I/V ratio X Current reading should be within this range. In addition, some Clamps require Batteries, make sure batteries are full

Elspec Scada has a post recording repair mechanism for some of the above mistakes.
Yet, it is recommended to verify your recording before leaving site on both real time
and recording side.
