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

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
