3 Debugging Outlines for Users.
This protection and its panel-assembled cabinet have been strictly debugged in the factory
and as they are delivered, they are in the perfect conditions and correctly connected. The user's
debugging on the protection is to check whether any damages have occurred in the transportation
and installation and whether the outgoing connections are correct. Since the perfect self-detection
functions of the software and hardware are provided in the protection, the failed parts can be
precisely located at the modules or ever chips. No adjustable components are mounted in the AC
sampling circuit, which is excellent in its vibration-proof capability and temperature property, so
the precision of the protection can be ensured by the delivery test. The test emphasis can be thus
placed on the parts of the status variable inputs(opto-coupler) ,
AC inputs, tripping and closing output circuits and signal circuits (relay contacts). Although
the following debugging procedures are directed at the protection as whole the debugging
operations had better to be made on the panels and cabinets, that is, the internal panel connections
should be included in the detection.
3.1 Check before energization
The advanced manufacturing technology is adopted and no adjustable components are used
and. A large quantity of the LSI circuits is employed in the protection. For the sake of its reliability,
in the normal test state, don't pullout any, even in the insulation check.
Before energization check whether the surface is perfect without any damages and loosen
parts for terminals and whether the parameters are consistent with the specifications. The special
tests should be made on the power supply voltage. TA rated current, tripping rated current and
closing rated current, etc.
3.2 Insulation check
The modules and terminals are connected in parallel (insulation test may be done on the
communication terminals). The insulation to the ground for modules is tested by the 500V
megaohmmeter and the tested insulation resistance should be larger than 100 MΩ. As the filters
