3 The technology
Functionning principle
The primary current IP flowing accross the sensor creates a magnetic flux.The magnetic circuit channels this magnetic flux.The Hall probe placed in the air gap of the magneticcircuit provides a voltage proportional to this flux.The electronic circuit amplifies this voltage and converts it into a secondary current IS. This secondary current multiplied by the number of turns NS of secondary winding cancels out the primary magneticflux that created it (contra reaction). The formula NP x IP = NS x IS is true at any time.The current sensors measures instantaneous values.The secondary output current IS, is therefore exactly proportional to the primary current at anymoment.It is an exact replica of the primary current multiplied by the number of turns NP / NS. This secondary current IS can be passed through a measuring resistance RM.The measuring voltage VM at the terminals of this measuring resistance RM is therefore also exactly proportional to the primary current IP.
