Circuit breaker analyser

April 2010 Maintenance, Test & Measurement, Calibration

The Programma EGIL is an automatic timer and motion analyser for medium and high voltage substation circuit breakers. It tests three-phase breakers up to 240 kV and is intended for use on circuit breakers with one contact per phase. EGIL incorporates features commonly found on more complex test systems, but is designed to be smaller, simpler to use and less expensive than other similar test sets. Its price makes it attractive to smaller utilities and it is an ideal supplementary product for maintenance departments at larger power companies and municipalities. The easy to use front panel keypad has pre-programmed standard circuit breaker operation modes, which ensure that operational training is minimal allowing quick easy use in the field.

EGIL’s three time channels are connected together on one side. Events consisting of parallel contacts equipped with pre-insertion resistors are recorded and displayed simultaneously. There are two separate time channels for measurement of auxiliary contacts. To simplify on-site hook up, EGIL comes with ready made multicable 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 or via the built-in printer. EGIL has a built-in sequencer that sets the instrument automatically for the next sequential breaker operation.

Intended primarily for measuring travel (motion), the optional analogue input channel finds many other uses. If this channel is not installed, all associated menu commands are hidden. EGIL can also be equipped with an optional serial interface (RS-232C) for communication with a PC.

Microdieseling – the explosions you never hear
Maintenance, Test & Measurement, Calibration
Microdieseling is a pressure-induced thermal degradation mechanism in which entrained air bubbles are compressed so rapidly that the surrounding oil ignites, producing soot, varnish and sludge. WearCheck explains how it happens, why the damage varies, and how oil analysis detects it.
