Megger PMM-2 Multi-Function Measuring Instrument
The Megger PMM-2 is a Multi-function Measuring Instrument; an ideal instrument for use in general electrical systems maintenance, electrical machine repairs, protective relay testing or in monitoring power at the electrical service entrance. Motor starting currents, voltages, and power can be captured for analysis.
The PMM-2 is designed to perform fast, accurate checking and testing of protective relay and meter installations during commissioning and in routine maintenance.
During meter installations the instrument can be configured to measure phase-to-phase voltage, single-phase current amplitudes, and phase angles.
The PMM-2 can be combined with a voltage or current source for test and calibration of virtually any type of protective relay.
Megger PMM-2 Key Features:
- Integrated onboard LCD touch-screen display
- Multi-colored graphics with intuitive navigation
- Built-in report generator
- Portable battery-operated instrument
- Measure and display up to four voltages and four currents simultaneously or up to eight currents
- Accurate phase angle measurements at low current levels
- High-speed sampling and data recording
- Built-in timer and event logging
- Available in the standard PMM-2 or rugged PMM-2R models
The Megger Power Multi-Meter, PMM-2 is the next generation multifunction instrument for measuring AC or DC voltage and current, primary, and secondary voltage and current, power, reactive power, power factor, phase angle and frequency of a single-phase or three-phase electrical system.
In the single-phase mode, the PMM-2 is easily configured to measure the amplitude and phase angle between any two voltage and current inputs. These measured quantities are then displayed in an enlarged font size for easier reading on a graphic display. In three-phase mode, all measured quantities are displayed simultaneously on a large, easy-to-read graphic display.
The unique software in the PMM-2, combined with a built-in, microprocessor-based timer, is specifically designed to ease testing and commissioning of protective relay systems, including induction unit pickup and timing tests.
The internal timer responds to a variety of start and stop gates, including the application of ac or dc voltage, and opening or closing of dry contacts.
The PMM-2 is a menu-driven instrument equipped with data-retention capabilities. It can be used to automatically store measured data using a user defined trigger. With a sampling rate of 28.8 k samples/second, and with 64 GB of memory, over 60 minutes of data can be stored on-board in non-volatile memory. The date and time can also be set, which can be used to start and stop data logging.
Accurate phase angle measurement at very low current levels, which can be displayed either as lagging or leading angles, is another feature of the PMM-2. The user can choose phase angle readings to be displayed as 0 - 360 degrees (leading or lagging) or ± 180 degrees.
Any current or voltage transformer ratio up to a ratio of 9999:1 or 9999:5 can be input into the instrument. The displayed value on the PMM-2 is the primary line value of the circuit under test. The values measured will be displayed as primary values eliminating the need for making conversions.
