Dorman Smith

Das Impsc genannte robuste Instrument dient zur Ermittlung von Kurzschlussstrom und zur Messung des Schleifenwiderstandes.
Das große analoge Anzeigeinstrument ist umschaltbar von 200 A oder wahlweise 2 kA bis zu 20 kA Maximalstrom.
Außen-, Neutral- und Schutzleiter können so auf korrekten Anschluss überprüft werden, das Instrument ist für 415 V bzw. 240 V kalibriert.

English translation of German description:
IMPSC was developed to enable simple measurement of PSC and avoid the complicated exercise of acquiring details of cable sizes, lengths and source characteristics to enable its calculation. Errors introduced during calculation by assumptions relating to impedances of high voltage systems, busbars, joints, etc, are eliminated.
This is an almost vintage instrument for measuring prospective Short Circuit Current and earth loop impedance, it's called IMPSC or PSC.
It is housed in a robust and fully insulated moulded case and is provided with two substantial terminals for connection to the source.
It's calibrated for use under either line-to-line (415 V) or line-to-neutral/earth (240 V) conditions. The measured PSC is corrected to the nominal system voltage, indication of which is provided. A range change switch enables coverage of PSC's from 200 A upwards and 2 kA upwards, the maximum readable figure being 20 kA.
The lower range is also calibrated in ohms at 240 V thereby enabling measurements of the external earth loop impedance of installations to be made directly.
The instrument comes with an english manual in a transport case with the probes shown in the picture.
