Description

Set the parameters for controlled (overreach) zones.

Zone Z1B	delay T1B
Zone Z1L	delay T1L

Select the measurement control parameters for voltage-controlled overcurrent fault detection or impedance fault detection.

Set the parameters for the fault detection program selected in address 1500. Also used to set all parameters for overcurrent detection only.

Set the parameters for determination of a fault loop in a grounded system

Set the parameters for determination of a fault loop in isolated or compensated systems.

Select the type of power swing blocking protection (three options), and set the power swing polygon and vector values.

Program the settings for pilot protection, permissive underreach transfer scheme.

Program the settings for pilot protection, permissive overreach transfer scheme. This includes setting the echo keying function on or off, the echo delay time, signal duration, and transient blocking time.

Program the settings for emergency overcurrent protection, including turning the function on or off.

Turn the waveform capture function on or off, select whether waveform capture is initiated by fault detection or by trip command, and indicate whether waveform records will be sent to a communications device connected to the front or to the rear port.

Control the sensitivity of the measured values monitoring functions. Also program the settings for the fuse failure monitor, if used.

Configure the relay for ground fault detection in systems with an isolated or compensated starpoint.

Configure the relay for high-resistance ground fault protection in a grounded system.

Configure directional comparison ground fault protection settings.

Configure the relay for nondirectional ground fault protection.

Program how the auto-reclose function interacts with the protection functions, and set reclose cycle times.

Configure the fault location function.

Run the preprogrammed directional test of the individual measurement loops. All six measurement loops should indicate the correct direction of the load flow.

Run the preprogrammed trip-close test using the internal auto- reclose function.

Check the operation of the circuit breaker tripping function and the operation of the circuit breaker. This test is independent of the automatic reclose function.
