Unbalanced Voltage

An excessive unbalance between pha-

ses in a 3-phase system will lead to mo-

tor overheating and failures. 

The maximum allowable unbalance is 

2%.  Voltage  unbalance  can  be  defined 

as 100 times the maximum offset of the 

three voltages (i.e. three phases) minus 

the average (regardless of the sign), di-

vided by the average.

Example:

If the three voltages measured in a line 

are 221 V, 230 V and 227 V, the avera-

ge will be:

(

221 + 230 + 227)/3 = 226 volts 

The unbalance percentage is:

100 x (226 - 221)/226 = 2.2%

This result indicates the presence 

 

of an unbalance above the maximum 

allowable value of 0.2%. The phase 

unbalance can result in a current unba-

lance of 20%, leading to an increase in 

motor winding temperature and reducing 

motor life.

Procedures

Belt Tension Measurement

A tension meter such as the one 

showed in Fig. 3 will be required to 

measure the belt tension. The pro-

per  deflection  is  determined  by  the 

result of the division of the distan-

ce between sheaves by 64 (inches). 

If a tension meter is not available, 

press the belt with the thumb. The belt 

should  present  a  deflection  of  approx. 

 

10 mm. If replacement for a new one 

is required, set tension to the belts and 

allow them to work for several hours un-

til they adapt to the sheave channels, 

then set tension again.

Liquid Sight Glass

When the sight glass displays bubbles, 

one or more of the following problems 

may be present:

a.

 Lack of refrigerant.

b.

 Clogged drier filter.

c.

 Expansion valve is too open.

d.

 Low subcooling.

e.

 Presence of non-condensables. 

A yellow color indicates the presence of 

residual humidity in the refrigerant circuit.

During normal operation the sight 

glass display should be green with no 

bubbles, indicating that the refrigerant 

load in the refrigeration circuit is correct 

and that the refrigerant is dehydrated.

Condenser Coil

The condenser coil should be cleaned 

with a soft brush and compressed air 

jets or low pressure water jets in the 

opposite  direction  of  normal  air  flow. 

Move the hose vertically and adjust the 

hose pressure so that it doesn’t damage 

the fins.

CAUTION:

!

Do not crush the fins during 

the cleaning process. This will 

reduce the heat exchange.
