EGIL – Circuit Breaker Analyzer (One Break Per Phase)

EGIL™, which incorporates benefits gained from experience with our larger instrument, is intended for circuit breakers with one contact per phase. Smaller and simpler, EGIL is equally versatile – and EGIL’s price makes it attractive to small power plants. Moreover, it provides an ideal supplementary instrument for maintenance departments at large power companies.
EGIL is designed to test circuit breakers having one main contact per phase. Its three time channels are connected together on one side. Events at 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 hookup, 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 or via the built-in printer. EGIL is easy to use – a built-in sequencer (program unit) sets the instrument automatically for the next sequential breaker operation.
Intended primarily for measuring travel (motion), the optional analog input channel finds many other uses as well. If this channel is not installed, all associated menu commands are hidden.
EGIL with the SDRM option together with the SDRM accessory enables static and dynamic resistance measurements.
EGIL can also be equipped with an optional USB interface for communication with a PC and the CABA Win™ Circuit Breaker Analysis Software.

Key features

  • Suitable for testing timing and travel on all circuit breakers with single interrupter per phase
  • Extremely easy-to-use and reliable
  • Two separate timing channels for measurement of auxiliary contacts
  • Analog measurement channels for travel transducers or general voltage/current measurements
  • Static and dynamic resistance measurements along with the SDRM201 accessory

The EGIL is an automatic timer and motion analyzer for medium- and high-voltage substation circuit breakers. It 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. It’s price makes it attractive to smaller utilities and it is an ideal supplementary product for maintenance departments at larger power companies and for testing contractors.
