Instantaneous power, efficiency and harmonics on inverters and motors
Power Analyzers
Efficiency measured across an inverter and a motor at the same instant, which is the only way the loss adds up.

What this group is for
Written as engineering fact. Nothing on this page states a specification the manufacturer has not supplied.
Simultaneous multi-channel measurement across input, DC link and output, so efficiency is a measurement rather than a subtraction of two separate ones.
Bandwidth that survives fast switching devices, where the harmonic content is the measurement.
Motor input alongside torque and speed, so electrical and mechanical power are compared on one time base.
Harmonic and noise analysis on the same acquisition.
Highlighted models
Model data to be supplied
Specific Power Analyzers models are quoted against the application, because the right one depends on the range you need to resolve and the conditions on site.
Tell us what you are measuring and we will name the models that cover it, with the ranges and accuracy classes written out in full.

Where it is used
Four situations this group is bought for, and the points on a real installation where it is connected.
- Inverter and motor drive efficiency evaluation.
- EV drivetrain and rapid-charger development.
- Power conversion R&D on wide-bandgap devices.
- Standards-referenced harmonic measurement.
Typical measurement locations
Instantaneous power and conversion efficiency
Inverter / drive
Efficiency is only real when input and output are measured at the same instant, on the same time base.
Transients and multi-channel waveforms
Motor
Start-up, regeneration and the fault that happens once all live in the same recording.

Power Analyzers: which one fits your measurement?
Give us the quantity, the range you need to resolve and the conditions on site. We will name the models that cover it and say plainly where they stop.
What has to be true inside the company
Four criteria of innovation, and the reason a measurement can be trusted outside it.
Increasing customer value
Production system
A production system built so that a measurement need turns into a delivered, calibrated instrument without the customer absorbing the delay.
Delivering peace of mind to customers
After-sales service
An instrument is only as good as the number it still reports in year five. After-sales service exists to keep that number trustworthy.
Pursuing productivity and precision
Manufacturing capabilities
Precision is a manufacturing capability before it is a specification. It is held in the process, not promised in the catalog.
Creating new customer value
Collaborative development of new products
When a field has no instrument for the quantity it needs to see, the instrument gets developed with the customer who needs it.
