Know what reached the property
before the claim was filed.
When your policyholders run TENA, every supply event at their property is timestamped and stored off-site. Their claim pack shows what electrical event reached the site, and when, so assessment starts from a record rather than a recollection.
Electrical damage claims turn on one missing thing: a record of what the supply actually did.
Events leave no trace
Surges and sags last milliseconds. Weeks later, only the damaged equipment is left to inspect.
Grid-wide or one property?
Without measurement at the site, a network event and a local fault look the same on paper.
Silent failures go unseen
A spent surge arrester or a bad restart pattern goes unnoticed until it becomes a claim.
- Loss reportedThe policyholder attributes equipment damage to a power event.
- Site visit arrangedThere is no other way to form a view of what happened.
- Event inferredDays or weeks later, from whatever survived.
- Decision made on limited informationWith no record of the supply at the time.
- Loss reportedThe event is already on record.
- Claim pack providedVoltage, current and frequency at the property around the time of the failure.
- Event placed in contextWhether nearby sites on the same network recorded the same event.
- Assessment starts from evidenceYour assessors decide, with a record of what reached the site.
TENA documents what electrical event reached a property, and when. It does not claim to establish what caused a particular failure. That remains your assessment.
What the record showed.
A valid CoC that was no longer true
Earth impedance had degraded and the surge arrester was close to failure, on a property with a clean certificate of compliance. Both were flagged early and the owner remediated before anything failed.
A generator, not the grid
During municipal powerline work, voltage fell to 194V and frequency rose to 52.8Hz, the signature of a generator supply. Without the record the event would have been described as a grid fault.
Load imbalance nobody had noticed
L2 was carrying 48% of total load against a 33% balanced norm. Structural, not transient: the kind of condition that quietly ages equipment. Correcting it is electrical contractor work; the measurement showed where to look.
Five sites, one recorded event
TENA devices at five sites across Kloof recorded the same voltage sag at the same instant, showing it was an eThekwini network event rather than a fault at any single property.
* Full event records available under NDA
One event. Five sites.
One consistent record.
A network of devices shows whether an event was on the wider network or began and ended at one property.
