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.

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. 12 To stay on the safe side, find out more about NHP Concept Emergency Lighting Test Units at nhp.com.au/more/lighttu
