Automeg Automatic 500V Motor Insulation Tester

The Automeg is designed to produce a low current, high voltage which is applied to the motor winding. The circuit includes means for measuring leakage currents and for triggering alarms for selected levels of leakage. These alarms may be the existing high level alarm light and horn, or can be wired into the telemetering terminal board. The AUTOMEG/SUBMEG module includes a green sunlight visible LED display light to indicate power and a red sunlight visible LED display light to indicate one (1) megohm motor winding leakage resistance to ground. The AUTOMEG/SUBMEG module will automatically alarm if the motor winding leakage resistance drops to one (1) megohm or less. An optional model that inhibits the motor from starting at a low meg reading is also available. A motor reset button is included along with a by-pass switch so that the AUTOMEG can be by-passed in the event of an emergency situation. A new feature of the AUTOMEG/SUBMEG module is a manual test button to test the internal circuitry of the AUTOMEG/SUBMEG. Also included is a yellow LED that has been added to indicate when 500 volts DC is applied to the motor windings before starting. This latest major breakthrough in preventative maintenance eliminates the need for an electrician to manually test the insulation resistance of the motors. In addition to the relatively low cost of the versatile AUTOMEG/SUBMEG module, savings are compounded because of the fact that motor burnouts (due to moisture penetration) and motor failure emergencies will be virtually eliminated and repair work can now be efficiently scheduled.
