Description

GE General Electric Technical Specifications: IS200VTURH1A

The procedure to test this element is identical to that outlined in Section 17.7.5: PHASE INSTANTANEOUS

IS200VTURH1A Characteristics

  1. Set a current of 0.2 of nominal and inject into the ground current input (terminals G10,H10).
  2. Set a 3Io current to 0.2 of nominal and in-phase with the ground current (this is the trip direction) and inject

into the relay via the phase current inputs.

  1. Increase the lagging angle of 3Io. At an angle lagging the ground current by 90 ± 2°, any output relays pro

IS200VTURH1A grammed for this condition should operate if the function is set to Control. If the function is set to Alarm,

check that the ALARM and MESSAGE indicators are flashing, the Neutral Directional Reverse alarm mes

sage is displayed, and any output relays programmed for this condition are operated.

  1. Continue to increase the lagging angle until the block message disappears at an angle lagging the ground

current by 270 ± 2°. Turn the current off.

IS200VTURH1A Test Connections per Figure 17–5: NEUTRAL DIRECTIONAL TEST CONNECTION WITH POLARIZING

IS200VTURH1A CURRENT.

As operations of each neutral directional sensing element have been checked under voltage and current polar

ization, it is only necessary to check that both directional elements are operational, and that either element can

IS200VTURH1A block tripping for reverse faults.

  1. Set Van to 60%, and Vbn = Vcn to 100% nominal voltage at phase angles of 0°, 120°, and 240°, respec

tively.

  1. Inject a current of 0.2 x nominal into the phase current input of the relay (3Io) at an angle outside the trip

ping region of the set MTA, as compared to faulted phase voltage Van. The Neutral Directional Reverse

alarm should appear.

  1. Inject a current of 0.2 x nominal, lagging the 3Io current by 180°, into the ground current input. The block

alarm should remain.

  1. Increase the angle of the ground current lagging 3Io current through a complete 360° rotation back to the

original angle of lagging by 180°. The block alarm should remain throughout the rotation as the voltage

polarized element is still blocking.

  1. Maintaining the ground current angle lagging 3Io by 180° increase the angle of 3Io lagging the Van voltage

through a complete 360° rotation back to the original angle. The block alarm should remain throughout the

rotation as the current polarized element is still blocking.

  1. Increase the angle of the ground current lagging 3Io current until the currents are in-phase. The block alarm

should remain.

  1. Maintaining the ground current angle in-phase with 3Io increase the angle of 3Io lagging the Van voltage

until into the permitted region. The block alarm should disappear when the angle reaches the tripping

region
