Section 10 Power Direction Test
This module is special for power direction relay test, which divided into two trials
according to the power direction relay wiring, the first 0 degrees wiring, second is 90 degrees
wiring. User-selectable any way wiring, the program automatically dichotomy test boundary
corner, and automatically calculates the power direction relay sensitive angle.
1. Current, voltage selection
(1) If 0 degrees wiring, choose [UA
、
IA],[UB
、
IB]or [UC
、
IC].
(2) If 90 degrees wiring, choose [UAB
、
IC],[UBC
、
IA]or [UCA
、
IB].
2. The rated voltage: 57.735V, rated current: 5.000A.
3. [Reset time] is the time of no current, voltage output, generally 1 second.
4. [Output time] is the time with output current and voltage, generally 1 second.
5. [Sensitive angle] is the angle
voltage leading current. ( Boundary angle
boundary angle 2 ) / 2.
6. Wiring-as shown:
