产品详细资料
W1（3）接地时间OC形状：选择要用于绕组1（3）的接地时间过电流元件的时间过电流曲线形状。有关时间过电流曲线形状的描述，请参阅第5-58页的时间过电流图。•W1（3）GROUND TIME OC MULTIPLIER（接地时间OC乘数）：输入乘数常数，所选时间过电流曲线形状（基准曲线）将通过该乘数常数在时间上偏移。•W1（3）GROUND TIME OC RESET（接地时间OC复位）：输入所选时间过电流曲线形状（基准曲线）在时间上偏移的乘数常数。•W1（3）GROUND INST OC 1（2）PICKUP：输入接地电流水平（以继电器标称电流为单位），超过该水平，绕组1（3）接地瞬时过电流1元件将拾取并启动延迟定时器。•W1（3）接地INST OC 1（2）DELAY（延迟）：输入接地电流必须保持在拾取电平以上的时间，然后元件才能工作。注：对于接地瞬时过电流1的绕组2和3以及接地瞬时超电流2元件上的所有绕组，上面的信息和下面的方案逻辑是相同的。限制接地故障保护通常应用于具有阻抗接地Y形的变压器。它旨在为百分比差分元件检测不到的低幅度故障电流提供灵敏的接地故障检测。
W1(3) GROUND TIME OC SHAPE: Select the time overcurrent curve shape to be used for the winding 1(3) ground time overcurrent element. Refer to Time Overcurrent Curves on page 5–58 for a description of the time overcurrent curve shapes. • W1(3) GROUND TIME OC MULTIPLIER: Enter the multiplier constant by which the selected time overcurrent curve shape (the base curve) is to be shifted in time. • W1(3) GROUND TIME OC RESET: Enter the multiplier constant by which the selected time overcurrent curve shape (the base curve) is to be shifted in time.• W1(3) GROUND INST OC 1(2) PICKUP: Enter the level of ground current (in units of relay nominal current) above which the winding 1(3) ground instantaneous overcurrent 1 element will pickup and start the delay timer. • W1(3) GROUND INST OC 1(2) DELAY: Enter the time that the ground current must remain above the pickup level before the element operates. Note The messages above and scheme logic below are identical for windings 2 and 3 of ground instantaneous overcurrent 1 and all windings on the ground instantaneous overcurrent 2 element Restricted ground fault protection is often applied to transformers having impedance grounded wye. It is intended to provide sensitive ground fault detection for low magnitude fault currents which would not be detected by the percent differential element.
