Circuit breaker analyser
September 2013
Electrical Power & Protection
Megger’s EGIL circuit breaker analyser is suitable for testing timing and travel on all breakers that have a single interrupter per phase. In addition, when used in conjunction with the SDRM201 accessory, the instrument can be used to carry out static and dynamic resistance measurements in SF6 switchgear. This includes arcing contact length in conjunction with Megger’s CABA Win software.
Although the EGIL is available at a very attractive price, no compromises have been made on its versatility or performance. It is therefore an ideal choice for the timing or maintenance of simple circuit breakers for operators of small power plants, contractors testing switchgear, commissioning engineers and MV switchgear builders.
The EGIL has a built-in sequencer that automatically runs the selected breaker operating sequence while making the appropriate measurements and recording the results. In addition, menu-driven procedures invoke sensible default settings, thereby eliminating the need for time-consuming pre-setting. Megger’s EGIL test set offers three timing channels for the circuit breaker main contacts. Main contacts and pre-insertion resistor contacts can be timed on the same channel, with the results recorded graphically and numerically on an integral print-out. Results are also shown numerically on the instrument’s large, easy-to-read display.
Two additional galvanically isolated timing channels are provided for auxiliary contacts. In addition, an analog channel is available as an option. While primarily intended for monitoring contact motion, this channel also has many other applications.
For EGIL test sets that have the SDRM option installed, the SDRM201 module extends the facilities to allow accurate resistance measurements to be made on circuit breaker contacts and other low resistance devices. When used with the test leads provided, the SDRM201 is capable of supplying an instantaneous current of 200 A DC, falling to 140 A after one second. Multiple tests can be run with only a short waiting time between them.
Used in conjunction with the SDRM201, the EGIL test set supports dynamic resistance measurement from 0 to 32 m, and static resistance measurement from 0 to 2 m. The inaccuracy of static resistance measurements is 2% ±2 μ or better.
To complement the EGIL circuit breaker analyser, Megger has introduced a new version of its CABA Win computer-aided breaker analysis software, the R03A. Designed to run under Microsoft Windows on a standard PC, this adds full support for static and dynamic resistance measurements; new test plans for applications where the EGIL is used with the SDRM201; and 19 new timing parameters for multiple operations.
