VACUUM CHECK  
Hazardous voltages are  
WARNING  
present during dielectric  
testing which can result in  
severe injury or death.  
Only qualified personnel  
should conduct this testing.  
A sufficient level of vacuum is necessary for  
proper performance of the vacuum interrupters.  
Although vacuum leaks are rare, the vacuum  
integrity should be checked periodically. The  
relationship between dielectric breakdown  
voltage of the contact gap and internal vacuum  
interrupter pressure has been found to be  
generally predictable. Therefore, vacuum  
interrupter integrity is checked by performing a  
high potential test across the open gap of the  
interrupter.  
TEST PROCEDURE:  
1. The contactor should be disconnected from  
the main circuit and be in the OFF position.  
2. Connect all the line side primary terminals  
together and to the output of the vacuum  
checker or AC hi-pot machine. Connect all  
the load side primary terminals together and  
to the ground terminal of the vacuum  
checker or AC hi-pot machine.  
TEST EQUIPMENT:  
Toshiba offers a compact vacuum checker (Type  
CI35-1D, Figure 11) which enables a quick and  
easy check on vacuum interrupter internal  
pressure. Alternatively, any commercially  
available AC high potential tester may be used  
which is capable of delivering at least 25 milli-  
amperes at 10 kV for a period of one minute.  
3. Increase the voltage from zero to 10kV AC at  
a rate of approximately 1kV per second.  
Hold the voltage at this value for 1 minute  
and observe the current drawn by the  
interrupter. See Figure 12.  
PRECAUTIONS:  
4. Decrease the voltage back to zero.  
Applying abnormally high voltage across a pair  
of contacts in vacuum may produce X-rays. The  
radiation may increase with the increase in  
voltage and/or decrease in contact spacing. X-  
radiation produced during this test with  
recommended voltage and normal contact  
spacing is extremely low and well below the  
maximum permitted by standards.  
As an  
additional safety measure, however, it is  
recommended that all personnel keep at least 1  
meter (3.3 ft) away from the vacuum circuit  
breaker while this test is performed.  
Radiation exposure hazard.  
WARNING  
X-rays may cause illness or  
injury. Stay at least 1 meter  
(3.3 ft) away from the circuit  
breaker during the vacuum  
check test.

CRITERIA:

procedure a few times.

2. If the contactor fails to meet criteria 1, then  
repeat the test on each pole separately to  
identify the damaged interrupter or

3. If the voltage can be held for 1 minute and  
the current flow does not exceed 5 milli-  
amperes, the interrupter has a sufficient  
vacuum level.  
After the test is complete, discharge any residual  
static charge from the primary terminals of the  
circuit breaker.  
If a vacuum checker or AC hi-pot tester is not  
available, a DC hi potential test may be  
conducted. If a DC test is conducted, the test  
voltage must be increased to 14kV DC. The test  
duration for DC tests and the criteria for  
acceptance remain the same as for AC tests.  
Do not use DC hi-pot  
WARNING  
testers which employ  
unfiltered half-wave  
rectifiers. The peak  
voltages produced by these  
testers may exceed the  
recommended value of  
14kV. This can result in the  
production of harmful X-  
rays and may invalidate the  
test results.

MECHANICAL SERVICE LIFE  
The normally energized type has a mechanical  
service life of 2.5 million operations. The  
mechanical service life of the vacuum  
interrupters is 500,000 operations.  
The criterion for the maximum number of the  
capacitor current switching operations is shown  
in Figure 14. The vacuum interrupter should be  
replaced when the number of switching  
operations in the graph is reached.  
For the components listed in Table 4,  
replacement or detailed inspection and cleaning  
are recommended after the indicated number of
