Surge Arrester Ratings: 15KV
Metal oxide surge arrester ratings per IEEE C62.11. Includes arrester rating (kV), MCOV, TOV capability, and maximum discharge voltage at 10kA. PK = voltage class, SK = arrester_rating_kV (Number).
| voltage class | arrester rating kV | duty cycle rating kV (kV) | energy class | housing material | max discharge voltage 10kA kVcrest (kV) | mcov kV (kV) | notes | standard | tov capability kV 1s (kV) |
|---|---|---|---|---|---|---|---|---|---|
| 15KV | 9 | 9 | 1 | POLYMER | 32.7 | 7.65 | Effectively grounded system | IEEE C62.11-2012 | 11.7 |
