The ability of a capacitor to accumulate an electrical charge is termed its capacitance, and it is this value that is measured by a capacitance meter. The simplest method of measurement is to apply an electrical current to a discharged capacitor, and to then measure the rate at which the voltage in the capacitor changes. With a known input, this process can be used to determine the capacitance of relatively large capacitors with a small test current.
The ABB CB-2000 Portable Capacitance Meter is an advanced measurement unit especially developed for measuring the capacitance of high power capacitors without making any disconnections within the capacitor bank.
In order to minimize power consumption, the low voltage (less than 1.4 V) test signal of the ABB CB-2000 Portable Capacitance Meter is generated only when a measurement is made.
The measurement frequency of the ABB CB-2000 is automatically adjusted according to the measured capacitance for best possible results, and to ensure reproducibility, up to five measurements can be stored and shown for each measurement object.
The measurements produced by the ABB CB-2000 are time stamped and the internal temperature at the time of measurement is stored as well. The data can later be downloaded to a PC for storage and analysis using the accompanying software.
The capacitance value is clearly displayed on the CB-2000 LCD, legible both in daylight and dark environments.
Short-circuit proof, the CB-2000 has a measuring range of 0-1000 μF.
