Intelligent Dielectric Loss Testervalid until: 07 Jan 2023date published: 07 Jan 2022
The Intelligent dielectric loss tester also applies to the measurement of tgδ and electrical capacity of high voltage electrical equipments in the workshops, laboratories and research institutes.
It could measure non-grounded or grounded high voltage equipments adopting positive and negative connection method. Besides, it could measure the tgδ of capacitor voltage transformer and capacitance of main capacitor C1and C2.
Control panel: printer, keyboard, indicator and communication transferring.
Variable frequency power supply: SPWM switching circuit is adopted to generate and output high-power sine wave stable voltage.
Step-up transformer: the output of variable frequency power supply is stepped up to the measuring voltage. The maximum reactive power output is 2KVA/one minute.
Standard capacitor: internal Cn. It is the measuring basis.
Cn current detection: it is used to detect the internal standard capacitor current, 10μA ~ 1A. The input resistance is
