Trip Coil Tester

A variable DC voltage is needed to test a circuit breaker. Substation batteries should not be used since this entails considerable risk for testing personnel, testing equipment and also for the equipment being tested. The best way to ascertain whether or not solenoids and protective mechanisms are sluggish or working properly is to perform a test at minimum tripping voltage. The minimum trip voltage test is described in international and national standards such as IEC 62271-100, ANSI C37.09 etc.

B10E can be used to test breaker coils in this manner. It provides a ripple-free variable DC voltage that can easily accommodate a high, variable load.

  • Reliable and stable power supply for circuit breaker testing
  • Continuously variable 24-250 V AC or DC output
  • Separate outputs for close coil, trip coil and spring charging motor voltage
  • Direct triggering for minimum trip voltage testing
  • Operate with a breaker analyzer for efficiency in testing sequence

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.
