Innovating Electrical Safety
The weakest part of an electrical circuit is its earthing integrity and hence the most important aspect from an electrical safety perspective. Yet once designed and installed, we often forget to verify its integrity! When was the last time you verified the integrity of the earth stake at your home? In truth, even we in the industry overlook it yet frontline protective devices RCD’s/RCBO’s, require a low impedance earth path in order to provide electrical protection and when not present, electrical safety can be compromised.
A ‘good/low impedance earth’ may be compromised by many factors including corrosion, hot joints and aging installations but by far the most variable and overlooked is the ground itself. Soil types such as sandy/rocky environments, concrete and bitumen pose a real problem making a low impedance environment difficult and at worst impossible to achieve. Add in moisture and environmental changes and the problem is exacerbated.
Unearthed or IT systems are also problematic for RCD’s due to lack of an earth-path and the 1st and 2nd fault scenario. Although widely regarded as the safest earthing system, they are not widely used as a result.
The RVDSAFE® technology is essentially an electrical safety isolation mechanism. Whilst the RVD® performs a similar function to the “safety” switches or Residual Current Devices (RCD’S), its operation is different to that of the normal RCD. The RVDSAFE® Technology provides tripping characteristics that are equal to or better than those of the standard RCD and in some cases, it can provide tripping in response to faults that will not activate RCD’s. The RVD® is designed to accompany any RCD/RCBO to provide ‘an additional layer’ of electrical protection. The device enables enhanced protection in the TN (MEN), TT and IT earthing systems. When a voltage above a predetermined level of 43V is detected, triggering the RVD® which triggers the RCD/RCBO isolating the circuit in under 20mSec.
Enhancing Electrical Protection
The RVD® significantly enhances electrical safety, saving lives, reducing risk and protecting downstream equipment from electrical damage.
The RVD® technology works in both ‘earthed and uniquely unearthed’ environments, significantly reducing the risk of personnel experiencing an electric shock incident.
Our technology provides and ‘additional layer of electrical protection’ in earthed or unearthed systems by detecting a voltage leakage to frame.
When coupled to an RCD/RCBO, you are provided with enhanced electrical protection within all earthing systems and high impedance environments. RVDSAFE® are raising the bar on electrical safety!
