Arc faults in medium voltage electrical equipment can be devastating. One of the most feared hazards of the electrical industry, a failure of electrical equipment causing an arc causes astronomical releases of energy, with temperatures exceeding 35,000 degrees.
If this arc occurs in a device or location with no dedicated pressure release, the equipment becomes a bomb, rupturing under the massive energy and spraying molten metal and shrapnel in the vicinity.
The only way to prevent catastrophic arc fault’s from causing an explosion is to design equipment to safely vent the pressure. This design should be type tested and compliant to standards ensuring public safety.
For electricity distribution equipment such as pole mounted reclosers, the priority becomes even higher. No longer is the risk of explosion contained within the substation, but the risk occurs in the city, out in suburbia and the countryside. If your pole mounted equipment is not arc fault vented, the consequences of an explosion can be disastrous.
Fortunately, modern technology designs of switchgear make arc fault vented designed pole mounted equipment an accessible technology for electricity distribution network providers and private industry.
The NOJA Power OSM Recloser is the worlds only solid dielectric insulated recloser with type tested arc fault venting.
If an arc fault occurred on distribution switchgear resulting in loss of property or life, it would be challenging to justify the choice not to select arc fault venting when investments are essentially equal.”
NOJA Power are dedicated to making the safest, most reliable switchgear to modernise the electricity distribution grid. The OSM Recloser is the benchmark for safety in outdoor medium voltage distribution switchgear.
