Chapter 4 Measurement
4.3.4 Use caution to heat generated by induction heating
In a strong magnetic field due to high frequency and large current, the metal
may generate heat due to induction heating. (Applicating this is IH's
electromagnetic cooker)
Since the Rogowski coil has a coiled structure in which a copper wire is
wound around a core material, the coil itself, which is a metal, may generate
heat by the same principle.
The Rogowski coil can not be used even within the absolute maximum di/dt
under conditions such that the coil itself generates heat due to induction
heating.
CAUTION
<Example in which there is a possibility of heat generation by induction
heating>
· Drive current of electromagnetic cooker etc.
· Driving current of welding machines, quenching devices, etc. using
induction heating
· High frequency power supply output used for semiconductor manufacturing
equipment, high frequency drive current

・ Do not use under conditions where the sensor
coil generates heat due to induction heating.
Even if the absolute maximum di/dt is within the range, the
coil itself is metal, so induction heating causes the coil itself
to generate heat, which may cause smoke, fire, or
malfunction.
