6.8 INSTANTANEOUS HDO UNIT

The instantaneous HDO unit will react differently depending on how the signal is applied. If the signal is applied
suddenly with no prefault current, the operating time will be longer. If a prefault current is applied prior to the
fault the operating time will be shorter. The following test determines that the instantaneous unit is working cor-
rectly and confirms the operating time for faults applied with no prefault current.

Connect the relay as shown in Figure 6–2: DIAC 66K TOC INVERSE TIME TEST SETUP on page 6–4. Set
the instantaneous unit pickup to 2 Amps (for the 5 Amp rated relay) or 0.4 Amps (for the 1 Amp rated relay)
with a zero IOC delay setting. Also set the TOC pickup to its lowest setting not including zero. This allows the
Instantaneous HDO unit to function without coordinating with the TOC unit. Apply 6 Amps (for the 5 Amp rated
relay) or 1.2 Amps (for the 1 Amp rated relay) and measure the operating time. The operating time should be
between 32ms and 46ms. This time is subject to dependent on the multiple of pickup current and the fault inci-
dence angle. A graph of how the instantaneous unit varies as a function of input current is provided for refer-
ence in Figure 2–17: IOC CURVE FOR THE HDO INSTANTANEOUS UNIT on page 2–19.
