ABB MV sensors:
General definition (IEC 60044-8):

No primary/secondary converter used in ABB MV sensors nowadays
= no active electronic needed inside of the sensor, no additional power supply = pure passive sensors
Signal integration for current sensors done at relay side

Sensors are produced with small manufacturing tolerances.
Due to the linear characteristic of sensor, measurement
error caused by manufacturing tolerances can be
compensated by using of correction factors in IEDs.
Correction factors used for current and voltage sensors:
Amplitude correction factors „aI“ and „aU“
4 decimal places
Phase error correction factors „pI“ and „pU“
4 decimal places
expressed in degrees
Improving measurement accuracy: Correction factors

CT needs to consume the energy to be able to transfer the
primary current to the secondary current.
The energy consumption is represented by power losses in
time.
The CT active power losses consist of:
power losses in primary winding
hysteresis and eddy-current losses
power losses in secondary winding
power losses in burden
Negligible energy consumption

Typical switchboard was selected where were calculated
2 varints with CTs and one variant with sensors:
A) CTs with secondary rated current 1A
B) CTs with secondary rated current 5A
C) Sensors
The selected switchboard consists of 14 panels:
2 Incoming feeders with CTs 1000/x/x A
8 Outgoing feeders 1 with CTs 200/x/x A
4 Outgoing feeders 2 with CTs 100/x/x A
All CTs have 2 cores:
Protection core class 5P20, 20VA connected to the
IED
Metering core class 0.5Fs5, 5VA connected to the
analog ampere-meter
