GENERAL OVERVIEW OF CURRENT TRANSFORMERS CURRENT TRANSFORMER is used for measurement of electric alternating currents. When current in a circuit (primary current) is too high to directly apply to measuring instruments, a current transformer produces a reduced current (secondary current) accurately proportional to the current in the circuit, which can be conveniently connected to measuring and recording instruments. A current transformer also isolates the measuring instruments from what may be very high voltage in the monitored circuit. Relationship between primary and secondary currents is...

GENERAL OVERVIEW OF CURRENT TRANSFORMERS Power requirements for measuring apparatur and relays: • Analog moving-iron meters 0.7 – 1.5VA • Rectifier current meters 0.001 – 0.250 VA • Multi-range current meters 0.005 – 5.000 VA • Current recorders 0.300-9.000 VA • Bimmetalic ammeters 2.5 – 3.0 VA • Power meter 0.2 – 5.0 VA • Power factor meter 2.0 – 6.0 VA • Meters 0.4 – 1.0 VA • Relays 0.2 – 6.0 VA • Power transducers 0.5 VA • Energy meters 2.5 VA Internal losses of copper wiring: CONNECTION DIAGRAMM OF CURRENT TRANSFORMERS Where: I – Secondary nominal current, L – Distance in [m], qCU –...
