Working in potentially explosive atmospheres is hazardous enough without having concerns that the voltage being supplied to temporary lighting is no longer within certified limits.
How can anyone be absolutely sure what voltage is being supplied, especially in a typical, long cable FPSO situation? Could it be one volt more or less than the certified safe range?
Reassurance is now available from Wolf Safety Lighting, whose latest technology gives an immediate warning when voltage either slips below or exceeds certified limits, even by just one volt.
Their SOVI™ technology – it stands for Safe Optimal Voltage Indicator – removes all doubt, giving operators the confidence that temporary lighting is operating safely, effectively and at the optimal voltage.
Unique to Wolf Safety products, the groundbreaking technology is now incorporated into its ATEX and IECEx certified Hazardous Area Temporary Lighting range, further enhancing safety in potentially explosive atmospheres.
It also ensures that a lighting solution is operating effectively and at the optimal voltage.
In the unlikely event that a light is operating at a voltage above the maximum certifi ed limit, the beam will pulse from bright to dim, giving a clear warning that action is needed to ensure that work can continue safely in the hazardous area.
However, it is more likely that issues will arise at the lower end of the voltage range. For example, if too many 24-volt lights are strung together and the transformer is overloaded, voltage could drop below the optimal level and light output will reduce incrementally as the input voltage falls.
If this does occur, SOVI™ ensures the light will pulse bright, indicating that the lamp is not within its certified voltage range, though the light itself is still safe as it is certifi ed down to zero volts.
