SEL-387E Instruction Manual 

DC Ratio Blocking (DCRB) 

Set E87Wx=Y1 to make the fourth-harmonic, (PCT4), dc ratio blocking (DCRB), and harmonic 
restraint (HRSTR) settings available.  Some magnetizing inrush cases contain very little harmonic 
content but contain a dc offset.  The SEL-387E Relay can detect the dc offset and use it in the 
blocking (not restraint) logic.  Enable this function by setting DCRB = Y. 

Harmonic Restraint (HRSTR) 

Set E87Wx=Y1 to make the fourth-harmonic, (PCT4), dc ratio blocking (DCRB), and harmonic 
restraint (HRSTR) settings available.  Even harmonics (second and fourth) can be used to provide 
security against magnetizing inrush currents during transformer energization.  Choose between 
harmonic blocking and harmonic restraint.  Harmonic blocking treats the second and fourth 
harmonics independently and blocks the relay when the second- or fourth-harmonic content 
(harmonic current as a percentage of the fundamental current) exceeds the PCT2 or PCT4 setting, 
respectively.  For example, assume the following: 

PCT2 = PCT4 = 20 percent, and the harmonics in the differential current are: 
second harmonic = 15 percent, fourth harmonic = 7 percent 

In this case, the relay does not block because neither harmonic content exceeds its particular 
setting.  But when the second-harmonic content increases to 21 percent, the relay blocks, 
regardless of the value of the fourth-harmonic content present in the differential current.  
Increasing the fourth-harmonic content to exceed the PCT4 setting while the second-harmonic 
content remains lower than the PCT2 setting yields the same result. 

Harmonic restraint is more secure than harmonic blocking since it adds the values of the second- 
and fourth-harmonic currents together and raises the relay characteristic by the sum of the two 
values.  In the example, second-harmonic c fourth-harmonic content = 15 p 7 
percent = 22 percent and relay tripping is restrained when it would not have been blocked. 

Set HRSTR = Y to select the harmonic restraint function and automatically enable Independent 
Harmonic Blocking (IHBL). 

Independent Harmonic Blocking (IHBL) 

Range:

 Y, 

N 

Upon energization of a three-phase transformer, at least two phase currents will contain inrush 
harmonics.  In traditional single-phase relays each relay compares the harmonic current flowing 
through the phase for that relay.  The SEL-387E Relay performs harmonic blocking in two ways: 

1.  Independent Harmonic Blocking (IHBL = Y) blocks the percentage differential 

element for a particular phase if the harmonic (second or fifth) in that phase exceeds 
the block threshold.  No blocking occurs on other differential elements. 

2.  Common Harmonic Blocking (IHBL = N) blocks all of the percentage differential 

elements if the harmonic magnitude of any one phase is greater than the blocking 
threshold. 

Common Harmonic Blocking is more secure but may slightly delay percentage differential 
element operation because harmonics in all three phases must drop below the thresholds for the 
three phases.
