The use of Sphere Gap Apparatus is an internationally accepted and standardised method by which the distance a spark can jump in air between two spherical electrodes is used to measure high voltages.
This apparatus has been designed and manufactured for use in accordance with EN 60052 Voltage Measurement By Means Of Standard Air Gaps.
We strongly advise that all tests using this apparatus are undertaken with reference to, and an understanding of, the latest version of EN 60052.
The apparatus is ideal for verifying the output range of high-voltage AC equipment such as Buckleys’ PST-100 and ST-AC Pro’ range of AC spark testers and is supplied with comprehensive assembly, set-up, calibration and adjustment instructions.
It has a measurement range of 17mm with a resolution of 0.1mm; thanks to its micrometer-screw adjuster.
Replacement phosphor bronze sphere electrodes are available from Buckleys and are quick and simple to install.
Features:
Robust 20mm aluminium chassis
2 x 4mm banana plug terminals
Micrometer adjustment
Replaceable phosphor bronze sphere electrodes
Simple set-up PVC support columns
EN60052 compliant design and construction
Ideal for testing Buckleys high-voltage AC products
