When a vacuum circuit breaker is commissioned or undergoes routine tests, it is very important to be able to ascertain whether or not the Vacuum Interrupter (VI) is intact before putting it back into operation.
VIDAR enables you to check the integrity of the vacuum interrupter quickly and conveniently by means of the known relationship between the flashover voltage and the vacuum interrupter. A suitable test voltage (DC) is applied to the breaker, and the result is known immediately.
Developed in conjunction with a major European utility, the PCA2 incorporates an advanced current injection unit together with a deep-memory high-resolution multichannel current/voltage/contact-event recorder. Both injection and recording functions can be used together or totally independently.
All instrument control is via a bright high-resolution colour touch-screen. The built-in printer provides an instant hard-copy printout. The USB port enables quick and convenient results transfer to a PC via ‘pen drives’ as well as the use of a barcode reader for quick site data entry.
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.
