5. Conclusion 
With the object of streamlining the execution of work of 
substation plant, a system has been built up which backs 
up the measurement work of the base plate position for 
installing the equipment . As the result of an error which 
might occur in the measurement work having been 
decreased with automation of the work reading the 
design value of the base position and the work preparing 
a document based on the measurement results, a 
prospect has been gained that the work time in the 
conventional hand work can be reduced greatly. 
Since this measurement work is a work in which lots of 
bases having the same shape are measured repeatedly, 
it is suitable for automation. After this, it is scheduled to 
examine an automatic measuring method with image 
sensing.
