Power & Protection Systems for Critical Infrastructure Applications

Protection, identification and management of electrical power risks are of primary concern to any company associated with critical infrastructure. Any point of single failure brings about large consequences at the operational level. Securing essential services is a unique challenge for organisations responsible for operational continuity.

Hospitals, Water Treatment, Emergency Services, Hotels, Banking and Finance, Malls, Airports, Public service buildings all depend on electricity for basic needs such as food, water, shelter, communication, employment and healthcare. In any of these there are many critical situations. For example, an extended interruption of telephone and communications services during a major disaster, whether it is a terrorist attack or a natural disaster, may put lives in danger if the public is unable to call emergency services, or if other emergency communications are disrupted.

This is not the place to save money on providing quality power with back up, these industries need top quality products with fail safe systems.

Case Studies

Redundant Charging System for runway lighting

A typical but essential application is Emergency Lighting, even more important when we are talking about Airports. Air traffic control, navigation and landing aids.

One of the landing aids, the Approach Lights System (ALS), is designed to guide aircraft approaching a runway under nighttime or other low-visibility conditions.

CAB408 is a charger for the CAB580-MOD-SYS system and consists of a 750W 24VDC boost charger, +P50S/1 and a digital V/I meter in a 3U 19-inch rack. Helios Power Solutions were enlisted by the Runway Lighting Project team to design and supply an automatic duel redundant charging system, used for charging batteries on two generator sets used to power the runway lighting.

A digital V/I meter monitors the output of the charger and the charger has a 32A 1P Output MCB to protect the load. The charger also has a LVD in the form of a relay that is externally controlled by the control unit. A P50S/1 blocking diode in the charger is fed externally from the control unit.

Battery Charger For Emergency Applications – Fire Service Rescue NSW

AMP-K5913 is specially designed to power a paging system which in turn sends out SMS alerts to residents in the bush fire danger zone to evacuate. The unit consists of internal 2 x 500W power supplies wired in N+1 redundancy to provide continuance of operation in case one power supply fails. The 1U unit also provides TCP/IP control and monitoring, battery circuit breakers and four-position breaker protected power distribution. Each distributed output can be power cycled remotely. The power system will also send email alerts in case of system failure.

Banking Security System Project

Description: This project involved a purpose-built security cabinet which can be seen below. Helios Power Solutions has provided these systems for many major banking corporations, including The National Bank and BNZ in New Zealand.

Helios Power Solutions Contribution: Helios Power Solutions designed, manufactured and supplied the security cabinet with alarms included for identifying mains failure and low DC voltage, using our own Security Systems Battery Charger. The Smartcharger provided battery back-up for CCTV cameras and alarm systems on banking premises. The batteries for power back-up were housed in the bottom of the cabinet, just below the Smartcharger.
