A 500 VAR capacitor bank is installed on a bus with a voltage of 480 V and a frequency of 50 Hz. The bus has wave distortion, both current and voltage harmonics as shown in Table 1.

a) Calculate the THD of the voltage at the bus and evaluate the value based on IEEE 519 2014 standard!

b) With the harmonic distortion that occurs, evaluate whether the capacitor is still operating as recommended in IEEE 18 - 2002 standard?

Table 1

Frequency (Hz)	Volt Magnitude Vh (Volts)	Line Current Ih (% from Fundamental)
50 150 250 350 550 650 850 950	831.4 33.3 16.6 10 5 0 0 0	100 15 10 5 3 0 0 0
