Maximum current up to 4000 A
Designed to avoid the power losses due to long cables connections
Connected to T 2000 or T 3000 unit with long (up to 20 m) low power control cable
Supplied with high current clamps and high current cables.
The BU 2000 option is an innovative design concept that allows to avoid the power losses due to long cables connections. To achieve this, the BU 2000 transformer is placed very close to the device under test (CT primary side, Circuit Breaker main contacts), thus avoiding losses on the high current cables. The BU 2000 is then connected with a long (20 m) low current cable to T 2000 unit. The option can use one, two or
four transformers, as a function of the maximum test current and/or the test duration (see table below).
