As electrical systems grow more and more complex, spikes, transients, surges, and sudden overvoltage events become more common. These can trigger a sequence of events that may lead to serious injury. Which is why test equipment must be designed to protect people who work in this high-voltage high-current environment.

The IEC 1010 safety standard was established to define four overvoltage categories (CAT I, CAT II, CAT III, and CAT IV) based on the magnitude of danger from transient impulses.

The new Fluke 73/77 Series III DMMs have been designed to meet the new IEC-1010 standards. More importantly, they have been approved by CSA as actually making these standards. Which means they are designed to protect you against transients in three-phase distribution systems, including:

• Single-phase commercial lighting.
• Equipment in fixed installations, such as switch gear and polyphase motors.
• Bus and feeder in industrial plants.
• Lighting systems in larger buildings.
• Appliance outlets with short connections to the service entrance.
