Field tests whose performance depend on customer requests and relevant standards, are as follows:
The whole system is tested by the HV/AC test after performance of site tests. Voltage level specified in IEC 60840 and IEC 62067 according to the subject system is applied for 1 hour.
After successful performance of the field tests and the HV / AC test, site is surveyed with the customer and any deficiencies are remedied. Finally, grid voltage is applied to the system for 24 hours and the system becomes ready for commissioning.
