Note: 

 

THMIP sets a minimum level of previous load current to be used by the thermal element, 

and is typically used when testing the element. For the majority of applications, THMIP 
should be set to its default value of zero, in which case the previous load current, Ip, is 
calculated internally by the thermal model, providing memory of conditions occurring 
before an overload. 

2.6  Negative Sequence Overcurrent Protection 

The negative sequence overcurrent protection (NPS) is used to detect asymmetrical faults 
(phase-to-phase and phase-to-earth faults) with high sensitivity in conjunction with phase 
overcurrent protection and residual overcurrent protection. It also used to detect  load unbalance 
conditions. This function is NOT for models 820 and 821. 

Phase overcurrent protection is forced to be set to lower sensitivity when the load current is large 
but NPS sensitivity is not affected by magnitude of the load current, except in the case of erroneous 
negative sequence current due to the unbalanced configuration of the distribution lines. 

For some earth faults, only a limited amount of zero sequence current is fed while the negative 
sequence current is comparatively larger. This is probable when the fault occurs at the remote end 
with a small reverse zero sequence impedance and most of the zero sequence current flows to the 
remote end. 

In these cases, NSP backs up the phase overcurrent and residual overcurrent protection. The NPS 
also protects the  rotor of a  rotating machine from over-heating by detecting a  load unbalance. 
Unbalanced voltage supply to a rotating machine due to a phase loss can lead to increases in the 
negative sequence current and in machine over-heating. 

Two independent negative sequence overcurrent elements are provided for tripping and alarming. 
The elements are programmable for instantaneous or definite time delayed operation.   

The tripping and alarming outputs can be blocked by scheme switches or a binary input signal. 

Scheme Logic 

Figure 2.6.1 shows the scheme logic of the NSP. Two negative sequence overcurrent elements 
NPS1 and NPS2  with independent thresholds output trip signal NPS1 TRIP and alarm signal 
NPS2 ALARM through delayed pick-up timers TNPS1 and TNPS2. 

ICD is the inrush current detector ICD, which detects second harmonic inrush current during
