Overvoltage test - Voltage shall be stepped from 258V to the test voltage and held for the test duration and then stepped back to 258V. Undervoltage test Voltage shall be stepped from 204.1V to the test voltage and held for the test duration and – then stepped back to 204.1V Additional Comments / Observations:: Over and Under Voltage Protection HV Where the is at the Generator shall demonstrate compliance with this EREC Connection Point HV Manufacturers Information G99 in respect of Over and Under Voltage Protection by provision of or by undertaking the following tests on site.
