Tan delta test attachment
Серия: SebaKMT
запросить ценуDescription
The tan delta test attachment enables a precise determination of the condition of the cable. Integral aging effects, such as the degree of humidity and “water treeing” can be simply recognised and quantified, making the tan delta test attachment the ideal
instrument for monitoring the condition of the cable.
The tan delta test attachment can be used as a stand-alone system with the portable VLF sine
systems from SebaKMT or in combination with the integrated VLF sine test systems in test vehicles.
The system achieves very accurate measurements because it measures at the high voltage potential and the measuring head can be placed very close to the test object.
The test unit and laptop have a wireless connection with a range of 75 m.
The EasyGo software simplifies operation and logging. Especially test sequences can be created easily and intuitively.
During the measurement, the voltage current and the loss factor δ are displayed graphically in real time, which means critical cables can be detected at an early stage and the voltage load on the test object can be kept to a minimum.
