  • Page 61 Electro-magnetic interference (EMI) and leakage currents NOTE • Install the earth leakage circuit breaker (ELB) on the input side of the converter unit. • In the connection earthed-neutral system, the sensitivity current is blunt against a ground fault in the inverter output side. Earthing (Grounding) must conform to the requirements of national and local safety regulations and electrical codes.
  • Page 62 Electro-magnetic interference (EMI) and leakage currents 3.1.2 Countermeasures against inverter-generated Some electromagnetic noises enter the inverter or the converter unit to cause its malfunction, and others are radiated by the inverter or the converter unit to cause the peripheral devices to malfunction. Though the inverter or the converter unit is designed to have high immunity performance, it handles low-level signals, so it requires the following basic techniques.
  • Page 63 Electro-magnetic interference (EMI) and leakage currents Noise Countermeasure propagation path When devices that handle low-level signals and are liable to malfunction due to electromagnetic noises, e.g. instruments, receivers and sensors, are contained in the enclosure that contains the inverter or the converter unit, or when their signal cables are run near the inverter, the devices may malfunction due to by air-propagated electromagnetic noises.

    Power supply harmonics Power supply harmonics 3.2.1 Power supply harmonics The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power factor correction capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and transmission path.
  • Page 67 Power supply harmonics 3.2.2 Harmonic Suppression Guidelines Inverters have a converter section (rectifier circuit) and generate a harmonic current. Harmonic currents flow from the inverter to a power receiving point via a power transformer.

However, if the carrier frequency exceeds 5 kHz, do not use that meter since an overcurrent losses produced in the internal metal parts of the meter will increase and the meter may burn out.

  • Page 95: Measurement Of Inverter Output Frequency

    Measurement of main circuit voltages, currents and powers 5.2.7 Measurement of inverter output frequency In the initial setting of the FM-type inverter, a pulse train proportional to the output frequency is output across the pulse train output terminals FM and SD of the inverter. This pulse train output can be counted by a frequency counter, or a meter (moving-coil type voltmeter) can be used to read the mean value of the pulse train output voltage.
