Vacuum interrupter tester

  • Tests the integrity of vacuum interrupters quickly, safely and easily
  • User defined voltage selection
  • Extensive voltage range
  • Easy to operate. Follows ANSI/IEEE standardized DC test methods.
  • Lightweight and portable

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.

 On-load protection condition analyser

  • Tests entire system (relay, breaker, tripping supply, CT, wiring etc.) simultaneously
  •  Records full protection operation sequence (before, during and after fault, trip or reclose)
  •  Captures critical ‘first trip’
  •  On or off-load injection test set or timer
  •  On or off-load breaker analyser
  •  General purpose oscillographic or event recorder with COMTRADE export
  •  Quick PC data transfer via USB drive

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.

 Circuit breaker analyzer for breakers with one break per phase

  • 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.
