PLC/DCS備件系統(tǒng)DS200TBQDG1A光纖接口板工控卡件

測試中應考慮施加到繼電器的電流的相位差（參見接地故障繼電器模塊手冊中開關(guān)SGF2/1和SGF2/2的功能以及cos項符號的規(guī)范）。如果同時滿足以下條件，模塊將啟動：-中性電流與相電流的剩余電流之比高于設定值I01/∑高壓側(cè)I1或設置I02/∑低壓側(cè)I2-方向差動電流超過運行特性值-基于二次諧波的閉鎖和外部閉鎖不會阻止啟動

PLC/DCS備件系統(tǒng)DS200TBQDG1A光纖接口板工控卡件The phase difference of the currents applied to the relay should be considered in the test (see the functions of switches SGF2/1 and SGF2/2 in the manual for the earth-fault relay module and the specification of the sign of the cos? term).The module starts, if the following conditions are fulfilled at the same time: - the ratio of the neutral current and the residual current of the phase currents is above the setting I01/∑I1 on the HV side or the setting I02/∑I2 on the LV side - the directional differential current exceeds the value of the operation characteristic - the blocking based on the second harmonic and external blocking do not prevent starting
