Our testing exceeds industry requirements. IEEE Std 386 requires a mandatory Partial Discharge production test and either an Impulse or an AC Withstand test. We run all three tests on all of our products.
All 600/900A Junctions have been designed and tested per the following industry standards:
| IEEE 386 – Industry Minimum Requirements | |||
|---|---|---|---|
| Voltage Ratings | |||
| Voltage Class, Phase-to-Phase | 15kV | 25kV | 35kV |
| Maximum Operating Voltage – (phase-to-ground) | 8.3kV | 15.2kV | 21.1kV |
| Corona Voltage Level – (partial discharge extinction voltage) | 11kV | 19kV | 26kV |
| AC Withstand – (1 minute) | 34kV | 40kV | 50kV |
| Impulse-Withstand Voltage – (BIL) | 95kV | 125kV | 150kV |
| Continuous Current Ratings | |
|---|---|
| Aluminum | 600A |
| Copper | 900A |
| Short-Time Current Ratings | |
|---|---|
| Aluminum | 25kA, 10c. and 10kA, 3s. |
| Copper | 40kA, 10c. and 10kA, 3s. |
