Negative Sequence Protection 46

Negative sequence protection detects unbalanced loads on the system.

Applications

• The application of negative sequence protection to motors has a special signifi-

cance. Unbalanced loads create counter-rotating fields in three-phase induction
motors, which act on the rotor at double frequency. Eddy currents are induced on
the rotor surface, which causes local overheating in rotor end zones and the slot
wedges. This especially goes for motors which are tripped via vacuum contactors
with fuses connected in series. With single phasing due to operation of a fuse, the
motor only generates small and pulsing torques such that it soon is thermally
strained assuming that the torque required by the machine remains unchanged. In
addition, the unbalanced supply voltage introduces the risk of thermal overload.
Due to the small negative sequence reactance even small voltage asymmetries
lead to large negative sequence currents.

• In addition, this protection function may be used to detect interruptions, faults, and

polarity problems with current transformers.

• It is also useful in detecting 1 pole and 2 pole faults with fault current lower than the

maximum load current.

Prerequisites

In order to prevent pickup chattering, the negative sequence protection becomes only
active when one phase current becomes larger than 0.1 x

I

Nom

and all phase currents

are smaller than 4 x

I

Nom

2.7.1

Definite Time element 46-1, 46-2

The definite time characteristic consists of two elements. As soon as the first settable
threshold

46-1 PICKUP

is reached, a pickup message is output and time element

46-1 DELAY

is started. When the second element

46-2 PICKUP

is started, another

message is output and time element

46-2 DELAY

is initiated. Once either time delay

elapses, a trip signal is initiated.
