6.5.1.2 Overcurrent and undercurrent element OC1 to OC4, OC5, UC1, UC2 and CBF and Earth

fault element EF1 to EF4 and SEF1 to SEF4

The overcurrent element is checked on the operating current value and operating time for IDMT
curve.

Operating current check

Figure 6.5.1.4 shows a testing circuit. The operating current value is checked by increasing or
decreasing the magnitude of the current applied.
