Basic harmonics measurement
THD measurement (V & I)
This value can be monitored to assess waveform distortion for each item, providing a yardstick that indicates the
extent to which the total harmonic components are distorting the fundamental waveform
✓ ✓ ✓ ✓ ✓
Harmonics 1 to 30 for V & I
When the level of the harmonic component is high, it may cause serious accidents such as overheating or noise in
motors or transformers, and burn out reactors in phase compensation capacitors.

Advanced harmonics measurement
Harmonics 0 to 50 for V & I
When the level of the harmonic component is high, it may cause serious accidents such as overheating or noise in
motors or transformers, and burn out reactors in phase compensation capacitors.
Detect the DC element on the AC circuit (0th order).

High order harmonics 2 kHz to 80 kHz
High-order harmonic components can damage equipment and power supplies, cause equipment operation to be
reset, or result in abnormal sound from TVs and radios.

Inter-harmonics
Inter-harmonics are caused when the voltage or current waveform is distorted due to static frequency conversion
equipment, cycloconverters, Scheribus drive, induction motors, welders, or arc furnaces. The term refers to fre-
quency components that are not a whole multiple of the fundamental wave.

Frequency uctuation
Frequency fluctuation occurs due to line separation caused by circuit issues, shutdown of a high-capacity
generators, or changes in the supply/demand balance of active power.
✓ ✓
‒ ‒ ‒
Transient voltage (impulse)
Transient voltage occurs due to phenomena such as lightning, breaker damage, or closure of the circuit breaker
or relay. It often occurs when there is a radical change in voltage or when the peak voltage is high.
✓ ✓
‒ ‒ ‒
Voltage dip (SAG)
Most dips are caused by natural phenomena such as lightning. When an equipment fault is detected and taken
ofine due to the occurrence of a power system ground fault or short-circuit, a large inrush current caused by a
motor startup or another load can occur, causing a temporary voltage dip.
✓ ✓
‒ ‒ ‒
Voltage swell (SURGE)
Swells occur when the voltage rises momentarily. Some examples of these are when a power line turns on or
off due to lightning or a heavy load, when a high-capacity capacitor bank is switched, when a one-line ground
occurs, and when a high-capacity load is cut off. This phenomenon also includes voltage surges due to grid-tied
dispersed power supplies (e.g. solar power).
✓ ✓
‒ ‒ ‒
Flicker
Flicker consists of voltage uctuations resulting from causes such as blast furnaces, arc welding, and thyristor
control loads. Manifestations include light bulb ickering.
✓ ✓
‒ ‒ ‒
Interruption (momentary power outage)
Interruptions consist of momentary, short-term, or extended power supply outages as a result of factors such
as circuit breakers being tripped due primarily to power company issues (interruption of power due to lightning
strikes, etc.) or power supply short-circuits.
✓ ✓
‒ ‒ ‒
Unbalance
Unbalance is caused by increases or decreases in the load connected to each phase of a power line, distortions
in voltage and current waveforms, voltage dips, or negative phase voltage caused by the operation of equipment
or devices that run with uneven power supply to load.
✓ ✓
‒ ‒ ‒
Inrush current
Inrush current is a large current that ows momentarily, for example when electric equipment is turned on.
