●
Dip
Dip, as the opposite of a swell, is a instantaneous voltage
decrease, most of the time caused by switching ON large
load e.g. motors or by downstream power line failure.
●
Interruption
Interruption is a power line cut-off from any source of
supply. It can be caused by a fault in a power line, which
causes switch gear to open.
●
Transients/Over Voltage (Impulse)
Transient is a very fast and momentary voltage increase
that can seriously damage devices connected to a power line. It may be caused by electrical switching events
such as instable contacts of r
but also by lightening. KEW 6315 can catch Transients
from 2.4 μs.

Inrush Current
Inrush current is a surge current that happens when
motors, large or low-impedance loads are switched ON.

Can you close your distribution board door during
surveys?
The KEW6315 facilitates safe testing by being extremely
compact and with two clever option extras: a magnetic
case(9132) for attaching it to the sides of metal enclosures
and a power supply adaptor(8312) which takes the power
for the instrument from the supply being measured.
