7. Testing 7.1 Production tests The following production tests shall be performed by the manufacturer on all connector components except ground bushings and grounding elbows: a) Partial discharge test (see 7.4) b) AC withstand or full-wave impulse withstand voltage (see 7.5.1 and 7.5.3) c) Test-point voltage test if applicable (see 7.17.2) Connectors shall be properly assembled with actual or simulated components that duplicate the fit and voltage stress distribution of the actual components. Bushing wells may be sample tested in accordance with ANSI/ASQC Z1.4 with an acceptable quality level of 2.5% using the normal inspection level. 7.2 Design tests The design tests listed in Table 5 shall be performed by the manufacturer to demonstrate compliance of the design with this standard. Design tests shall be performed using actual connector system components assembled according to the manufacturer’s instructions and using those materials supplied in the manufacturer’s packaging. 7.3 Test conditions The following test conditions shall apply unless otherwise specified: a) All parts that are normally grounded shall be connected to the ground of the test circuit b) Ambient temperature shall be in the range of 0 °C to +40 °C c) All ac voltages shall have a frequency of 60 Hz ± 5% and sine wave shape of acceptable commercial standards as defined in IEEE Std 4 d) Voltages shall be measured in accordance with IEEE Std 4 7.4 Partial discharge test The purpose of this test is to verify that the partial discharge minimum extinction voltage of the specimen is not less than the value given in Table 1. The test voltage shall be raised to 20% above the partial discharge minimum extinction voltage specified in Table 1. If the partial discharge peak value exceeds 3 pC, the test voltage shall be lowered to the partial discharge minimum extinction voltage specified in Table 1 and shall be maintained at this level for at least 3 s but not more than 60 s. Partial discharge readings taken during the interval 3 s to 60 s shall not exceed 3 pC peak.
