Page 26: Before Measurement
Chapter 4 Measurement 4.3 Before Measurement This section describes notes on accuracy and the handling of the Rogowski Coil Sensor when measuring the current using this instrument. 4.3.1 To Achieve Accurate Measurement As explained in Chapter 3 “Measurement Principle,” the Rogowski Coil is a wire rod wound tight around a tube-like wick material, as illustrated in Figure 3.1. - Page 27 Chapter 4 Measurement 4.3.2 Withstand Voltage Guarantee Range of Rogowski Coil Sensor The withstand voltage guarantee range of the Rogowski Coil Sensor is illustrated in Figure 4.4. The sensor cable’s withstand voltage guarantee range is the section covered with a gray tube (approx. 500 mm). Keep the section of the sensor cable where the withstand voltage is not guaranteed away from high-voltage parts.
- Page 28 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.
- Page 29 We recommend that you replace a deformed coil or a coil with its surface damaged, in order to maintain safety and accurate measurement. Contact Iwatsu office or our sales distributors for replacement.
