Current Transformer

A
current transformer is a device for measuring a current flowing
through a power system and inputting the measured current to a
protective relay system. Electrical power distribution systems may
require the use of a variety of circuit condition monitoring devices
to facilitate the detection and location of system malfunctions.
Current transformers and current sensors are well known in the field
of electronic circuit
breakers,
providing the general function of powering the electronics within the
circuit breaker trip unit and sensing the circuit current within the
protected circuit. Ground fault circuit breakers for alternating
current distribution circuits are commonly used to protect people
against dangerous shocks due to line-to-ground current flow through
someone's body. Ground fault circuit breakers must be able to detect
current flow between line conductors and ground at current levels.
Upon detection of such a ground fault current, the contacts of the
circuit breaker are opened to deenergize the circuit. Current
transformers are an integral part of ground fault circuit breakers.
Current transformer assemblies are often positioned between the line
side of a trip unit of a circuit breaker and the load side in order
to monitor the current therebetween. Current transformers in
electrical substations measure the system currents at predetermined
measuring points of the switchgear with a certain measurement
inaccuracy. The measuring points are typically located at all
incoming and outgoing lines and possibly also within the system, e.g.
for the busbar protection. The current measurement signals are used
for protective functions, for monitoring the substation, for
calculating performance data for operating purposes or for
consumption billing and for the representation on a display. The
output of the current transformer
provides a representation of the current flowing through the assembly
that is being monitored. Associated monitoring and control
instrumentation in combination with the current transformer may
provide critical system functions such as overload protection and
power usage monitoring.
