Industrial equipment needs a reliable power supply to
operate properly, use the dual input to obtain key power
measurements.
For single phase or 3-phase balanced systems, the dual inputs
of the Industrial ScopeMeter® 120B Series can measure ac+dc
rms voltage on channel A and ac+dc rms current on channel
B. The Fluke 125B can then calculate; frequency, phase angle,
active power (kW), reactive power (VA or var), power factor (PF)
or displacement power factor (DPF) and can also calculate the
power values for a 3-phase system where all phases have equal
voltage and currents. This applies to both balanced system and
resistive loads.
Easily obtain key power characteristics to validate a system
power.
Harmonics measurements
Harmonics are periodic distortions of voltage,
current, or power sine waves. Harmonics in
power distribution systems are often caused
by non-linear loads such as switched mode
dc power supplies and adjustable speed motor
drives. Harmonics can cause transformers,
conductors, and motors to overheat. In the
Harmonics function, the Test Tool measures
harmonics to the 51st. Related data such as dc
components, THD (Total Harmonic Distortion),
and K factor are measured to provide a com-
plete insight in to the electrical state of health
of your loads.
