What this group is for
Written as engineering fact. Nothing on this page states a specification the manufacturer has not supplied.
Continuous monitoring with event capture, so an intermittent disturbance is recorded the first time it happens rather than waited for again.
Records the disturbance and the conditions around it, which is what turns a complaint into a cause.
Standards-referenced measurement, so the result is admissible in a discussion with a utility or a supplier.
Installs on a live system with clamp sensors rather than requiring an outage.
Highlighted models
Model data to be supplied
Specific Power Quality 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.
- Investigating nuisance trips and unexplained equipment failures.
- Power quality surveys before and after installing new equipment.
- Verifying supply quality against a contract or a standard.
- Commissioning renewable generation onto an existing network.
Typical measurement locations

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

Power Quality 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.
