感性電流開閉試驗要求之細項。

請參考IEC 62271-100 (或CNS 15156-100 等同 IEC 62271-100)第 6 節 Type tests 及 6.111 Capacitive current switching tests 是否須測試CC2、LC2、BC2 主要決定於斷路器設計之功能與結構,使用場合及規格宣告之等級,如M1 ,M2 ,E1,E2,C1,C2 CLASS,型式試驗依上述宣告依IEC 62271-100 型式試驗標準執行不同等級對應之試驗如CC2、LC2、BC2 等。

例如：

4.107.2 Rated cable-charging breaking current
The rated cable-charging breaking current is the maximum cable-charging current that the
circuit-breaker shall be capable of breaking at its rated voltage under the conditions of use
and behaviour prescribed in this standard. The specification of a rated cable-chargingbreaking current is not mandatory; it is required only for circuit-breakers to which class C1 orC2 for cable-charging current switching is assigned.

請參考IEC 62271-100 T able 11 試驗項目如屬 Mandatory type tests 為必要測試, 其下表項目則依產品宣告規格及客戶協商要求決定是否測試？ 401附表一所列型式試驗項目僅供參考,型式試驗項目仍依選用標準(如IEC 或ANSI)型式試驗要求測試即可.但試驗對產品規格及宣告須註明清楚,另試驗機構必須為ILAC 認可之實驗室報告方被接受(特別留意)

4.107.3 Rated及第 4 節 Ratings
The characteristics of a circuit-breaker, including its operating devices and auxiliary
equipment, that shall be used to determine the ratings are the following:

Rated characteristics to be given on request
s) rated out-of-phase making and breaking current;
t) rated single capacitor bank breaking current;
u) rated back-to-back capacitor bank breaking current;
v) rated capacitor bank inrush making current;
w) rated back-to-back capacitor bank inrush making current.
The rated characteristics of the circuit-breaker are referred to the rated operating sequence.

4.107 Rated capacitive switching currents
Capacitive switching currents may comprise part or all of the operating duty of a circuitbreaker
such as the charging current of an unloaded transmission line or cable or the load
current of a shunt capacitor bank.
The rating of a circuit-breaker for capacitive current switching shall include, where applicable:
– rated line-charging breaking current;
– rated cable-charging breaking current;
– rated single capacitor bank breaking current;
– rated back-to-back capacitor bank breaking current;
– rated single capacitor bank inrush making current;
– rated back-to-back capacitor bank inrush making current.
Preferred values of rated capacitive switching currents are given in Table 9.
r.i.v試驗項目，是否可參IEC所示123KV以下產品可忽略。

依據IEC標準123KV以下產品可忽略.

參考IEC 62271-1 6.3 Radio interference voltage (r.i.v.) test

This test applies only to switchgear and controlgear having rated voltages of 123 kV and above and shall be made when specified in the relevant product standard. Radio interference voltage test is regarded as EMC emission test and covered under 6.9.1. Between 1 kV and less than 123 kV the r.i.v. effects are of a low level and are negligible.
容性電流開閉試驗(CC2、LC2、BC2)是否需全部進行，又或是能源局、台電綜研所有指定測試項目。

請參考IEC 62271-100 (或CNS 15156-100 等同 IEC 62271-100)第 6 節 Type tests 及 6.111 Capacitive current switching tests 是否須測試CC2、LC2、BC2 主要決定於斷路器設計之功能與結構,使用場合及規格宣告之等級,如M1 ,M2 ,E1,E2,C1,C2 CLASS,型式試驗依上述宣告依IEC 62271-100 型式試驗標準執行不同等級對應之試驗如CC2、LC2、BC2 等。

於國外取得之50Hz型式試驗試驗報告，回台換證是否有須注意事項。

國外試驗請試驗機構選用之試驗參數及條件須符合台灣60Hz條件,與頻率有關者如溫升試驗之限度,Makink Current Peak k選用2.6 及短路試驗與電容性電流試驗與啟斷特性有關者等等,能源局審查會以60Hz 參數及條件審查,此部分請特別留意,避免審查不通過。
