Performance of TBB
The device allows continuous operation under the steady-state overcurrent of 1.3 times the rated current due to overvoltage and high harmonics.
The device is allowed to run for a long time under the rated voltage of 1.1 times power frequency.
The device can set the inrush current limit value at the moment when the capacitor bank is put into operation, which is less than 20 times of the rated current of the capacitor bank.
Capacitor capacity deviation not exceeding -5%~+10% of the rated value The ratio of maximum to minimum capacity measured between any two line terminals in three phases shall not exceed 1.02.
The dielectric between the terminals of the capacitor unit must be able to withstand one of the following two tests, lasting 10s: power frequency AC voltage (2.15un);AC voltage (4.3un)
