I.L. 40-385.1B
• All features listed as standard for the Non-Pilot
MDAR V2.00 are included in the Pilot system
• Independent pilot phase and ground distance
units
• Permissive Overreach Transfer Trip (POTT) /
Simplified Unblocking
• Permissive Underreach Transfer Trip (PUTT)
• Directional Comparison Blocking Scheme (BLK)
• POTT or Simplified Unblocking Weakfeed
• • Instantaneous Forward Directional Overcurrent
Function for High Resistance Ground Fault Sup-
The following features are optional for the Non-Pilot and the Pilot MDAR V2.00:
• Optional communications attachment
RS232C/PONI
INCOM/PONI
• • Optional
16 sets of oscillographic data and intermediate
target data. Each set includes 7 analog graphic
inputs and 24 digital intermediate targets with 8
samples per cycle. Each analog input contains 1
prefault and 7 fault cycles. (Data collection can be
started by TRIP, Z2PU, Z2Z3 or ∆V ∆I depending
on the setting of OSC.)
• Optional FT-14 switches
• Optional Out-of-Step Block
• Optional Single-Pole-Trip (SPT) logic and out-
puts:
– SPT/RI1 on first φGF and 3PT on other fault
types.
– 3PT/RB if reclosing on a permanent fault.
– 3PT/RB if second phase(s) fault during single
phasing.
– 3PT on a time delay limit (o.35-5.0 sec in 0.05
sec steps) if the system fails to reclose (62T).
