Hengelo, Netherlands

SHORT CIRCUIT TESTSConfiguration of tests:

Tested according to standard EN 50638 (2003)

Tray used:

CF105/450 (3 meters)

Span 1500

Coupled with fast coupler EDRN at 1/5th of the span

Cables:

Three 38mm outside diameter single core power cables in a trefoil formation.

They represent the most common form of cabling used and potentially the most difficult cables to test (the smaller the diameter the higher the strain on the cleats).

Cleats

Ellis Patents cleats. See details of rigs for cleat model.

SHORT CIRCUIT TESTSRig 1:

Cleat: ALPHA (aluminium)

Spacing of cleats: 600mm

Peak current: 70 kA (72.4 kA actual)

Represents a force of 13 152N on the cleats

SHORT CIRCUIT TESTSRig 2:

Cleat: VULCAN (stainless steel)

Spacing of cleats: 600mm

Peak current: 100 kA (104 kA actual)

Represents a force of 26 842N on the cleats

SHORT CIRCUIT TESTSThe lab:

3 cables are short circuited Close inspection before/after

High speed camera link up

SHORT CIRCUIT TESTSRESULTS

Rig 1: 70 kA

Class 1: Water spray:

Class 2: according to EIC draft

Rig 2: 100 kA

Class 1: Water spray:

Class 2: according to EIC draft

Class 2 test is equivalent to Class 1 test after the rig has already been tested once.
