The 100ADM mk4 provides commissioning and maintenance engineers with a flexible system for testing protective systems. It has an easy to understand panel layout and a simple user interface. The status of every function can be seen at a glance, and there are no complex menus to navigate. The 100ADM mk4 keeps the familiar user uinterface of previous models but adds a new metering system that accurately measures the RMS of a single cyle. It also features a new current limit mode to provide very fine control of very low currents, even into low impedance loads. Current limit mode also assists in testing self-powered overcurrent protection as fitted to many 11kV ring man units.

The unit has a range of outputs allowing injection of currents as low as a few mA and as high as 100A. Voltages up to 240V are available on the main outputs, allowing high impedance current relays and voltage relays to be tested. Four true RMS metering ranges are provided, allowing the full scale of the meter and trip level to be set independently of the selected output. Industry standard safety connectors are used on all inputs and outputs for convenience, reliability and safety.

The 100ADM is comprehensively protected by overcurrent, duty cycle and thermal trips, and keeps the user fully informed of any trip condition.

The back-lit display on the 100ADM mk4 is bright and clear with a wide viewing angle. The results of a test can be seen here as they appear on the display

A stabilised DC supply is provided to power the relay under test, along with an independently switched and isolated 110V AC output.

A very flexible two channel timing system is provided, allowing trip times, reset times and re-close times to be quickly measured to a high degree of accuracy. The timer auto-ranges to measure from 1ms to 99999.9s.

The 100ADM can be used to test many types of single phase secondary protection including:
•27/59 Over and under voltage relays
•37 Under current
•51 IDMT relays
•50/76 Intantaneous overcurrent
•59G Neutral voltage displacement
•79 Auto-reclosers
•2 Time delay relays
•51G/50G Earth fault relays
•67 Directional overcurrent (basic tests)
•52 Miniature circuit breakers
•Tripping relays
•Thermal relays
•90V Voltage regulating relays
