Active and apparent power, power factor

Power Meter

Power measured properly on a waveform that is not a clean sine, which on real equipment it never is.

What this group is for

Written as engineering fact. Nothing on this page states a specification the manufacturer has not supplied.

  • True power computed from simultaneous voltage and current samples, not inferred from RMS values.

  • Correct results on distorted and phase-shifted waveforms, where a simple meter quietly reports the wrong number.

  • Single- and three-phase configurations for the wiring actually in front of you.

  • Continuous measurement for standby, idle and loaded conditions in one run.

Highlighted models

Model data to be supplied

Specific Power Meter 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.

  • Power consumption and standby power evaluation of products.
  • Efficiency measurement on power supplies and converters.
  • Equipment acceptance testing against a power specification.
  • Energy studies on individual machines.

Typical measurement locations

Supply quality: sags, swells, harmonics, flicker

Incoming supply

Everything downstream inherits whatever arrives here. Measure it before blaming the equipment.

Power Meter: 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.
