Insulated EWP Electrical Testing
An insulated EWP is only as safe as its insulation. For crews working near live electrical apparatus, the dielectric integrity of the boom and platform is the barrier that protects them — and it degrades with age, contamination and damage. Periodic electrical testing confirms that barrier is still doing its job.
We coordinate dielectric and electrical testing for insulated units so their insulating properties can be verified and documented. It is specialised work that sits alongside routine and annual inspections, and it is what allows an insulated EWP to keep being used with confidence around live equipment.
Built For

- Anyone operating insulated EWPs in live-line environments
Equipment & Coverage
- Insulated boom lifts
- Insulated truck-mounted EWPs
- Insulated platforms and liners
- Insulated upper and lower boom sections
- Associated dielectric components
The Process
Confirm requirements
We identify the unit's insulation rating and the testing required under the applicable standard and manufacturer specification.
Prepare & clean
Insulated surfaces are inspected and prepared, since contamination and moisture directly affect dielectric performance.
Dielectric testing
The insulating components are electrically tested to verify their integrity against the required criteria.
Document results
Results are recorded so you have documented evidence the unit's insulation performs as required before it returns to live work.
Compliance & Standards
Insulated elevated work platforms are maintained and inspected under AS 2550.10 and designed to AS/NZS 1418.10, with dielectric testing carried out to verify their insulating integrity. Testing frequency is not something to guess at — the interval follows the applicable standard and the manufacturer's requirements for the specific unit and its rating. We test and document accordingly so your records reflect what is actually required.

Common Questions
How often does an insulated EWP need electrical testing?
The interval is not a fixed figure we would invent — it follows the applicable standard and the manufacturer's requirements for that specific unit and insulation rating. We confirm the correct testing regime for your equipment before scheduling.
Why does insulation need periodic testing?
Dielectric performance degrades over time through age, contamination, moisture and physical damage, none of which is obvious from a visual check. Periodic testing confirms the insulation still provides the protection crews depend on when working near live equipment.
What can reduce an insulated EWP's dielectric performance?
Contamination, moisture, surface tracking and physical damage to the insulated components can all reduce dielectric integrity. That is why the units are cleaned and inspected before testing, and why testing is repeated periodically rather than assumed to last.
Do you provide documentation of the results?
Yes. The testing is documented so you have clear evidence the unit's insulation meets the required criteria. That record supports your compliance obligations and gives operators confidence before returning the machine to live work.
