What this group is for
Written as engineering fact. Nothing on this page states a specification the manufacturer has not supplied.
Multiple test voltages so motors, cables, switchgear and low-voltage wiring are each tested at the voltage that is meaningful for them.
Trend-capable results, because insulation is judged by how it changed since last time, not only by today's number.
Automatic discharge after the test, which is a safety feature and not a convenience.
Continuity testing in the same instrument, so a bonding check does not need a second tool.
Highlighted models
Model data to be supplied
Specific Insulation Testers 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.

Ranges, accuracy classes and model numbers for Insulation Testers, by email. No call unless you ask for one.
Where it is used
Four situations this group is bought for, and the points on a real installation where it is connected.
- Periodic preventive maintenance on motors, cables and switchgear.
- Commissioning and handover testing of installations.
- Fault location on a circuit that trips its earth leakage protection.
- Condition assessment before a shutdown is scheduled.
Typical measurement locations
Insulation resistance of windings
Transformer
Insulation does not fail suddenly. It trends, and the trend is only visible if someone measured it last year too.
Earth resistance, phase sequence, live-line check
PV array / generation
The three checks that happen before anyone is allowed to start work.

Insulation Testers: 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.
