Arc Flashes


9

• Mainly occur in electrical devices that are 480 volt and up.

• Motor control centers and substations are a great source of faults.

Arc Flash Explosion


10

• – Forms the arc path through air

• – Expands to form blast wave • Vaporized metal and ionized air:

• Temperatures reach 35,000°F+

• Energy levels can reach 20-100 Cal/cm2

• Duration is less than 7/10ths of a second

• Proportional to energy and distance.

Damages from Arc Flash

UETS/ AVERNR/Iqbal Ibrahim

11

• High temperatures burns to skin

• Melting of synthetic clothing to skin

• UV and IR burns to eyes and skin

• Temporary or permanent blindness

• Pressure Wave can knock you down

• Decibel can reach 160 DB

• Neurological effect of a magnetic field

• Temporary or permanent personality changes

The End Results

Solution: Install MTAP 13


MTAP2 meets both OSHA and NFP 70E

definitions for safe voltage

Time consuming tag

out and lock out

procedures are

eliminated and in

seconds you can

connect and collect

accurate data to

determine your motor

health.

MTAP 2 Provides protection from Arc Flash

Before MTAP2 you need PPE to protect against Arc Flash

while connecting test leads & current probes

After installing MTAP2 there is no need to open the MCC door to make connections.

Test cable is connected to the connector installed on MCC Door
