Page 4: Introduction
Page 5 of 32 INTRODUCTION The circuit breaker analyzer and microOhmmeter model CBA2000 is a two-in-one test set. When used as a circuit breaker analyzer, it allows the off-line testing of the characteristics of all modern MV and HV circuit breakers. The test set measures CB operation times as they are defined in the IEC standard 62271-100;... - Page 5 All circuits have been designed to ensure safe operation in the noisy environment of HV and MV substations. The instrument is housed in a transportable aluminium box, that is provided with removable cover and handles for ease of transportation. The following table lists he key new features of CBA2000 with respect to CBA1000. PERFORMANCE CBA2000 CBA1000 COIL DRIVING 2;...

. External trigger. The test set features a Trigger Out output and a Trigger In input, that allow synchronizing up to 4 CBA2000’s. In this mode, one CBA2000 acts as the Master unit; its Trigger Out output will be connected to all other units, selected as Slave. As the Master starts the test, all other Slave units will measure the timing on Main, auxiliary and analog inputs. -
Page 10: Static Resistance Measurement (Optional)
2.8 S (OPTIONAL) TATIC RESISTANCE MEASUREMENT This measurement is performed connecting CBA2000 to the test sample and measuring its resistance. Test samples can be: joints, main contacts and so on. Main contacts resistance is measured in the closed position. . Test current, resistance measuring range, resolution and accuracy: see the table. -
Page 11: Dynamic Resistance Measurement (Optional)
With this measurement it is possible to record the main contact resistance during the CB close. The CB is open prior to test start: CBA2000 issues the Close command; as the contact closes, the test current passes through the contact, and CBA1000 measures the contact resistance variations during the close movement. -
Page 12: Pc Software
. Enhanced measurement features for movement – speed – acceleration control. The software will be upgraded for free until a new version is released. Upgrading is simple: just connect to the ISA WEB site, and download the latest version. This applies also to the test set resident program. -
