2TL-BL-SPC-2FC — Two-terminal line, blocking scheme, single phase comparison, two frequency channel.
2TL-UB-DPC-2FC — Two-terminal line, unblocking, dual phase comparison, two frequency channel (FSK PLC only); 
scheme cannot be used for breaker-and-a-half applications.
2TL-TR-DPC-3FC — Two-terminal line, permissive tripping, dual phase comparison, three frequency channel.
2TL-BL-DPC-3FC — Three-terminal line, blocking scheme, dual phase comparison, three frequency channel.
3TL-TR-SPC-2FC — Three-terminal line, permissive tripping scheme, single phase comparison, two frequency channel 
carrier to two other terminals.
3TL-BL-SPC-2FC — Three-terminal line, blocking scheme, single phase comparison, two frequency channel carrier to 
two other terminals.
3TL-TR-DPC-3FC — Three-terminal line, permissive tripping scheme, dual phase comparison, three frequency channel 
carrier to two other terminals.
3TL-BL-SPC-3FC — Three-terminal line, blocking scheme, dual phase comparison, three frequency channel carrier to 
two other terminals.

87PC BLOCK

 — Selects a Flexlogic operand that blocks operation of the phase comparison scheme (for example, an 

operand that indicates operation of a communications channel failure detector).

87PC SIGNAL SOURCE

 — Selects whether current is supplied from one current source (either single-breaker CT application or 

dual-breakers with CTs summed externally) or from two separate sources (breaker-and-a-half or ring configurations), 
where currents from both CTs are fed into the L60 individually.

87PC SIGNAL

 — A mixed I_2 – K 

×

 I_1 signal, mixed I_1+I_2 / K signal, or single 3I_0 signal can be chosen as the operating 

signal for the FDH and FDL detectors and positive/negative square pulses generation. The constant K in the mixed 
excitation signal is adjustable.

87PC MIXED SIGNAL K

 — Selects the K factor used in the mixed excitation operating signals I_2 – K 

×

 I_1 and I_1+I_2 / K. For 

the mixed I_1+I_2 / K mode, the setting range is limited from 0.08 to 0.25.

87PC MIXED SIGNAL REF ANGLE

 — This setting applies exclusively to the negative-sequence mixed mode operating current 

(“Mixed I_2-K*I_1”) and specifies a leading angular shift for the originally developed operating signal. The operating signal 
is always developed taking phase A as reference for calculating symmetrical components. This setting can be used to 
control the angular position of the operating current with respect to the voltage of any phase that can be used by the line 
carrier in a particular application. This allows minimizing the impact of positive corona on dependability of single-
comparison blocking schemes. Effectively this setting shifts the transmitted pulses in time with the intent to minimize—for 
the majority of faults—the overlap between the space periods and positive peaks of the voltage in the phase used by the 
carrier. Normally, this angle shall be adjusted to follow the conductor used by the carrier plus the extra line characteristic 
angle (approximately 90°).
The following setting rule applies particularly for blocking schemes.

Table 5-22: Setting rule

Some applications are not concerned with the corona effect, such as when the applied carrier uses narrow-band filtering, 
or similar techniques improving security and dependability of transmission.
Shifting the angle reference is considered an advanced principle and does not have to be used in all applications. If used in 
situations that are not concerned with the corona effect, this setting does not alter operation of the relay: neither improves 
it, nor impairs it. The only effect is in possibly different operating times for different fault types, with the average times 
unchanged.

NOTE

A two-frequency channel (2FC) can be either amplitude modulated (AM) on-off carrier or a high-low frequency 
shift keying (FSK) system.
In blocking schemes, the open breaker echo element must be disabled.
