TROUBLESHOOTING - continued

PROBLEM:

Harmonic current distortion exceeds 8% on one or more

 

phases at full load.

 

 

Possible cause:

On filters rated 52 amps and above, the capacitor assembly has not

 

been connected.

Solution:

Check interconnection of capacitor assembly with reactor panel

 

(Figure 26).

 

 

Possible cause:

A capacitor has failed.

Solution:

Inspect the tops of all capacitors for bowing. Replace failed

 

capacitors.

 

 

Possible cause:

Source impedance is less than 1.5%.

Solution

Add a minimum 1.5% impedance line reactor to the filter input

 

 

Possible cause:

Input source voltage harmonic distortion.

Solution

Identify equipment causing harmonic voltage distortion and add

 

filters as required or accept elevated THVD

Possible cause:

Line voltage unbalance exceeds 1%.

Solution:

Balance input line voltage to 1% or less.

PROBLEM:

Harmonic current distortion exceeds 5% on one or more

 

phases at full load.

 

 

Possible cause:

The input reactor required for a 5% filter was not installed. (See

 

Figure 38.)

Solution:

Install the required input reactor

 

 

Possible cause:

On filters rated 52 amps and above, the capacitor assembly has not

 

been connected.

Solution:

Check interconnection of capacitor assembly with reactor panel

 

(Figure 26).

 

 

Possible cause:

A capacitor has failed.

Solution:

Inspect the tops of all capacitors for bowing. Replace failed

 

capacitors.
