THE LOGICAL CHOICE FOR IMPROVING SAFETY
AND REDUCING INFRASTRUCTURE DAMAGE
NHP’s Arc LogiX system provides an end-to-end
flash migration solution to minimise power-
crippling infrastructure damage caused by arc flash
while increasing electrical contractor safety.
An arc flash is usually initiated by either a
breakdown of insulation or a foreign object, such
as a hand tool, causing a conduction path through
an air gap in a switchboard. When this occurs, an
arc is formed between phases or phase to ground.
The consequences of an arc flash include
significant damage to switchgear, conductors,
switchboards and the installation. However, the
biggest consequence is potential injury or death of
operators in the area.
The Arc LogiX system combines two powerful
technologies to detect and clear an arc fault within
an optimum timeframe.
The Arc LogiX CS smart touchscreen system
improves arc flash safety by using temporary
‘maintenance mode’ protection settings with
Terasaki AR ACBs. It can handle 12 ACBs per
system and display information which includes
circuit breaker energy management data and trip
history, and switchboard internal temperatures.
Manufactured by NHP and fully programmable
out of the box, it also has wireless email event
notification.
Arc LogiX Optical is a range of fast acting fibre
optic based arc flash relays suitable for MV and LV
applications, available in solid state or relay-based
technologies for both linear and point optic fibre
sensors. Delivering multiple zone monitoring,
it can be used as a complementary technology
layer to Arc LogiX CS or as standalone arc flash
mitigation technology.

SEE THE LIGHT WITH NHP’S EMERGENCY
LIGHTING TEST UNITS
NHP Concept’s updated Emergency Lighting Test Units provide a safe,
simple and time efficient testing method to comply with the six-monthly
testing requirements of AS/NZS 2293 standards.
During a test, the timer starts and a contactor cuts mains supply
so emergency and exit lights run on battery power. The inspection
continues until either the timer times out or the stop button is pressed
to cancel the test, and mains power is automatically restored to the lights
and the batteries recharge.
In areas accessible by the general public, the ELTKA test switch kit
provides manual operation with secure access to the test functions via a
key-operated, spring return switch.
For areas accessible by authorised personnel only, the ELTSA test switch
kit provides manual operation via the push button with a spring return
switch.
An added feature with the new ELTKA and ELTSA test switch kits is that
in an event of a power blackout they will allow for emergency lights
to remain on for 10 minutes giving time for normal lighting to regain
sufficient light warm up preventing a blackout period.
The NTSELS is an optional accessory used with the test switch kits that
is available for environments where ongoing monitoring is required and
features sensing of eight lighting circuits.
The compact design of the Emergency Lighting Test Unit from NHP
allows for easy connection to existing circuits and is also available in an
open version which can be retrofitted to an existing panelboard.
