Section 1
Safety Precautions
The dielectric withstand test generates voltages of up to 3000 volts ac at potentially
lethal current levels. Currents of as little as 5 mA at 120 volts can cause death, and the HT-
3000P-1A-AC is capable of generating 1 A at up to 3000 volts. The HT-3000P-1A-AC has been
designed to minimize exposure to high voltages. However, the potential for serious injury or
death exists and personnel should be aware when they conduct this test.
Test Personnel
Personnel require special training to conduct the dielectric withstand test. They should
understand electrical fundamentals clearly, and be aware that high voltage is adept and creative
at completing a path to ground. Instructions should include a warning against any metal jewelry.
Operators should not allow others in the testing area, especially when tests are being conducted.
Organization is to be stressed. The operator should keep the area free of unused leads and
equipment.
Testing Area
The area used for conducting the dielectric withstand test should be as remote as possible
from normal production line activities. Only personnel actually conducting the test should be
allowed in the area, and it should be taped or roped off to preclude casual entry by other
employees. In addition, the area should be marked "WARNING - HIGH VOLTAGE TESTING"
or the equivalent to warn others of the nature of the testing taking place.
The bench being used should be non-conductive, and any exposed metal parts should be
tied together and grounded. If a conductive surface must be used, it should be grounded.
Because of sparking during a dielectric test failure, it is not safe to conduct dielectric
withstand tests in combustible atmospheres.
It is imperative that a good ground be provided to the HT-3000P-1A-AC. Before
connecting the HT-3000P-1A-AC, ensure that a low-resistance ground is provided by the
building wiring. If the HT-3000P-1A-AC is used on a high-resistance grounding circuit,
dangerous high voltages may be present to the operator. In addition, the power to the Testing
Area should be provided with an easily reached shutoff switch which can be actuated by
personnel outside the Area if needed.
