TESTING
INTRODUCTION
This section provides procedures for testing the operation of BE1-67N relays. Separate test procedures
are provided for relays with sensing input ranges 1 and 2 and sensing input ranges 3 and 4. Use the
procedures that correspond to the sensing input range of your relay.
TEST PROCEDURES FOR SENSING INPUT RANGES 1 AND 2
The following paragraphs contain procedures for verifying the operation and timing curves of a BE1-67N
relay with sensing input range 1 or 2.
Operational Test Procedure
Following a preliminary test setup, BE1-67N operational testing consists of a time overcurrent pickup test,
an instantaneous overcurrent pickup test (directional and non-directional), V
O
directional verification, and
I
O
directional verification.
Preliminary Test Setup
1. Connect the BE1-67N relay as shown in Figure 5-1.
Figure 5-1. Typical Test Connections
2. Adjust the Tap Calibration control fully clockwise.
3. Set the Time Dial at 99.
4. Set the Tap Selector switch in position A.
5. Adjust the Directional, Instantaneous Overcurrent control and Non-Directional, Instantaneous
Overcurrent control fully clockwise.
6. Place the Characteristic Angle switch in the 0
°
position.
7. Set the Polarizing Source Select switch (locator A of Figure 2-2) for dual polarization (both the V
O
and
I
O
switches up).
