The Megger Programma EGIL is an automatic timer and motion analyser for medium and high voltage substation circuit breakers and is intended for use on circuit breakers with one contact per phase. Its three time channels are connected together on one side and events consisting of parallel contacts equipped with pre-insertion resistors can be recorded and displayed simultaneously. There are two separate time channels for measurement of auxiliary contacts. To simplify on-site hookup, the EGIL comes with ready-made multi-cable sets for both main and auxiliary contacts. Coil currents are measured automatically and presented together with other readings immediately after testing on the display window such as closing and opening time, comparison between phases, over-travel, Close/Open and Open/Close time.

• Pre-programmed with standard circuit breaker operation modes (Close, Open, Open/Close, Close/Open, Open/Close/Open) for ease of use.
• EGIL automatically measures or calculates circuit breaker timing characteristics such as opening and closing time.
• Simple menu-driven operating procedure makes setup and operation extremely easy for the test technician.
• Monitors the state (open or closed) of the circuit breaker and automatically determines the appropriate tests that can be performed next.
• Dual-function timing channels allow detection of both main and pre-insertion resistor contacts.
• User-programmable coil signal duration and delay times allow proper sequencing of each breaker operation combination (Close/Open, Open/Close or Open/Close/Open).
• EGIL monitors close and trip coil currents.
• Monitoring for auxiliary contacts (wet or dry) is also provided.
