EMTP-RV error message

Hello:

     I bult a simple model in the EMTP,but when I start the Simulation, it send out the following  warning message,

Error, Problem near singal  s13

A device attached to this signal is causing a floating network condition or other illegal condition.

Illegal conditions that may occur: switch type device loops, dependent device incompatibility

or ill-assorted conditions caused by some active device constraints

 

      So I want to know what is the mean of "Floating network or other illegal condition"

      Thanks

Hello GangLi,

 

this error message generally occurs when the system or part of the system is not grounded properly. For example, the transformer Delta winding is open circuited. The Delta section does not have the ground reference. To solve this issue, you can connect the stray capacitance (like 10 pF) or high resistance (1000Mohm) between the delta winding and ground.

 

Thanks

Regards

Hello. 

I tried to do a TRV study on a sample network. When i check the 'Run time-domain simulation and plot the TRV waveforms' in TRV page i face the following message:

Error. .mda output file does not exit. Make sure the simulation ran successfully.

please help me to fix the problem.

thanks.

Dear,

 

I hope this message finds you well.

Do you have the Matlab runtime installed in your machine?

 

Thank you very much for your attention.

Yours sincerely,

Mauro
