6.6 Conjunctive Tests
6.6.1
On Load Test
To check the polarity of the current and voltage transformers, check the load current, system
voltage and their phase angle with the metering displays on the LCD screen.
• Open the "Auto-supervision" screen check that no message appears.
• Open the following "Metering" screen from the "Status" sub-menu to check the above.
