Revolutionary Breakthrough in Electrical Safety for the EV Charging Market.

Many properties have poor and unreliable “as built drawings” where buried services connected to the PME infrastructure or drainage and sewer pipes are not accurately mapped out. This can lead to huge expense in time and money when installing traditional supplementary earthing systems.

No More Earth Electrodes !!

The O-PEN device can detect an open PEN fault on three phase TN-C-S (PME) infrastructures, and safely isolate the incoming supply or individual loads.

Allowing the installer to utilise the PME earth in line with BS: 7671 18th Edition Amendment 1:2020 Regulation 722.411.4.1 (iii), guaranteeing earth resistance values are maintained all year taking away the potential seasonal difference of traditional earth electrodes.

  • Simplifying installation
  • Reducing expensive and disruptive civils works
  • Saving time during installation
  • Increasing safety to the installer and end user

Electric Vehicle Chargepoint Installations

Used by many of the leading charge point manufacturers and installers in the UK the O-PEN protection device can help transform EV Charge point installation, especially where earth electrodes are used.

Allowing the charge point to be connected directly to the PME supply, negating the requirement for expensive and disruptive civils works when installing earth rods and can save £1000s per installation. Helping installation costs to be dramatically reduced.

Neutral Fault Detection for Commercial Buildings with 3 Phase Installations

Broken Neutral faults in three-phase systems are extremely dangerous as the single-phase (line to neutral) voltages can rise to the three-phase levels. This results in overvoltage that can be catastrophic to electronic appliances resulting in expensive insurance claims and create a potential fire hazard.

  • Single-phase voltages rising to 400V
  • Overheating of appliances
  • Potential fire risk
  • Danger of death from electrocution

Furthermore, electricity would travel back to the transformer via a different path, meaning that any bonded appliance or service connected to earth could become live. This is extremely dangerous, as you could suffer a serious electric shock if you touch something where electricity is present.

The O-PEN technology can also be used to indicate open-circuit neutrals and phase loss in parts of TN-S, and TT three-phase installations, which can be equally damaging to single-phase equipment. Using O-PEN technology gives the installation owner the information to help prevent the hazardous situation going undetected. A signal from the O-PEN can be used to send an alert via email or text, sound a siren, or even switch contactors or relays to isolate critical loads.

The Solution

Property Management Companies throughout the world will now be able to offer their client base the safety aspect that only O-PEN can give. This will allow a Monitoring System to fully utilize the capabilities of the O-PEN product in terms of early warning of risk disaster to Schools, Universities, Office blocks, and high rise residential buildings. Creating a phenomenal market for our future distributors of the product in their territory.
