Section 1
Introduction to Impulse Testing with the MegaPulse PF
series tester
The impulse test is designed to simulate impulse surges which occur in everyday life due to nearby lightning
strikes, switching transients, and other high-frequency faults on the power distribution network. Impulse
testing is the fundamental method for empirical verification of the adequacy of insulation. Other methods of
ensuring adequate insulation (AC or DC Dielectric Withstand testing, measurement of over-surface creep
age, through-air clearance, or distance-through-insulation) are all extrapolated from the results of impulse
testing. The impulse test is performed to ensure that the insulation in question will be able to function properly
when subjected to similar impulse surges in the field.
Safety Precautions
The impulse withstand test can generate voltages in excess of 5000V peak at potentially lethal current levels.
Currents of as little as 5mA at 120 volts can cause death; the MegaPulse can deliver currents of more than
500 Amps peak for very short time duration. 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 impulse 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 impulse test should be as remote as possible from normal production line
activities. Only personnel 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. Ifa conductive surface must be used, itshould be grounded. Because of sparking duringan impulse
test failure, it is not safe to conduct impulse testing in combustible atmospheres.
It is imperative that a good ground be provided to the MegaPulse tester. Before connecting the equipment,
ensure that the building wiring provides a low-resistance ground. If the MegaPulse tester 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.
CAUTION: Plug on power cord is disconnect device. 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.

Safety Techniques
The high voltage circuit of the MegaPulse Code 360 can be shut off at any time by turning OFF the rear
power switch. Always press TRIGGER to discharge the tester before turning OFF.
The MegaPulse tester is provided with a digital VOLTAGE ADJUST knob on the front panel. This voltage
setting should always confirm by pressing the VOLTAGE ADJUST knob before start any testing.
The MegaPulse tester is provided with a CHARGE switch that is in the unarmed "Standby" setting when the
tester is first turned ON. When the yellow CHARGE button is lit, the tester will not provide high voltage
until the CHARGE Button and the TRIGGER Button have been pressed in order. To prevent inadvertent
operation, the operator should be instructed not to press the CHARGE Button until the test is ready.
The MegaPulse tester has been designed for one-touch operation with the right hand. If possible, it should
be set up to the left and in front of the equipment under test. The equipment under test should be connected
to the MegaPulse tester and then left alone by the operator. After the operator is clear of the Tester and the
equipment under test, the operator should turn the rear-panel power switch to ON, press the CHARGE
Button, adjust the voltage to the desired level (as displayed on the front panel meter), then press the
TRIGGER Button, with his right hand. This will allow the greatest separation between the operator and the
test being conducted. Note that the CHARGE process will stop after 2 minutes if the TRIGGER button is not
pressed.
The MegaPulse tester is designed to bleed the high voltage away after the test has concluded. In order to
ensure that any voltage present in the equipment being tested has been completely bled away, the operator
should not unplug the equipment under test from the MegaPulse until the front panel meter reads a safe level
(40 volts or less is generally considered a safe level). Pressing the TRIGGER button before disconnecting
main power (or turning the equipment off) will ensure that the internal capacitors are discharged as much as
possible.
Safety Markings

Using the MegaPulse Impulse Tester
The impulse test involves high voltage and caution should be exercised when using the tester. The RETURN
lead is referenced to building ground when properly connected. However, both the OUTPUT and RETURN
leads must always be treated as Hazardous whenever the power switch of the MegaPulse is in the ON
position.
The MegaPulse PF tester is designed to bleed the high voltage away after the test has concluded. In order to
ensure that any voltage present in the equipment being tested has been completely bled away, the operator
should not unplug the equipment under test from the MegaPulse until the front panel meter reads a safe level
(40 volts or less is generally considered a safe level). Pressing the TRIGGER button before disconnecting
main power (or turning the equipment off) will ensure that the internal capacitors are discharged as much as
possible. CAUTION
High voltage generated by the MegaPulse tester is exposed during this test. A riskof shock exists.
Exercise care when using the MegaPulse unit.
Pressing the POLARITY switch on the front panel can change the polarity of the output waveform. The
polarity is Normal when the NOR indicator is lit. In this case, the high voltage will appear on the OUTPUT
as a positive pulse relative to the RETURN jack. When the polarity switch is in the Reverse position (REV
indicator is lit), the high voltage will appear on the OUTPUT as a negative pulse relative to the RETURN
jack. The polarity switch only operates when the CHARGE LED is lit, i.e. the output is not charged.
Note that the voltage meter may indicate that some residual voltage is present on the main storage capacitor,
even when the tester is first turned ON. This is due to inherent charging of the internal capacitors. Pressing
the TRIGGER switch will discharge the capacitors (be sure not to touch the output and return leads when
pressing the trigger switch).
Note that the peak amplitude of the measured output waveform is proportional to the voltage that is read on
the front panel of the MegaPulse, but it will always be somewhat lower. This is because the meter on the
MegaPulse is measuring the voltage on the main impulse storage capacitor. This voltage will intentionally
dissipate to some extent before reaching the output leads. Therefore, it is important to measure the peak
amplitude of the output waveform, and adjust the output of the MegaPulse accordingly.
Determination of Passing and Failing results can prove difficult. To obtain the most accurate results, it is
generally necessary to perform multiple impulse tests on a few different test samples (that have adequate
insulation to pass the impulse test). Take note of the impulse waveshape, amplitude, and duration. Also note
how much variance there is in the waveshape from test to test. Also (if possible), perform impulse testing on
some test samples that are known to have inadequate (or damaged) insulation. Take note of the impulse
waveshape, amplitude, and duration, when an insulation breakdown occurs.

Testing
This section describes how the MegaPulse Code 360 tester is used to conduct a test. The test can be stopped
immediately at any time by turning OFF the rear-panel power switch.
CAUTION: Make sure you have a load of at least 50Ω connected between Output and Return or use internal
load for testing purposes.
1. Connect the tester to a proper source of supply using the included 18 AWG power supply cord.
2. Plug the Output and Return test leads into the jacks on the front panel.
3. Connect the ends of the test leads to the equipment under test.
4. Turn the Tester on. Toggle the POLARITY switch as needed so that the NOR or REV indicator
is lit.
5. Note that the Voltage meter may indicate that some residual voltage is present on the main storage
capacitor, even when the tester is first turned ON. This is due to inherent charging of the internal
capacitors. Pressing the TRIGGER switch will discharge the capacitors (be sure not to touch the
output and return leads when pressing the trigger switch).
6. If no load is connected at the Output, turn ON the 50Ω load switch.
7. Push the yellow CHARGE button. Verify the red TRIGGER indicator is now lit.
8. Adjust the digital VOLTAGE knob up to the desired level. Push the red TRIGGER button, when
the desired voltage is displayed on the front panel meter.
9. Note that the peak amplitude of the measured output waveform is proportional to the voltage that
is read off the front panel of the MegaPulse, but it will always be somewhat lower. This is because
the meter on the MegaPulse is measuring the voltage on the main impulse storage capacitor. This
voltage will intentionally dissipate to some extent before reaching the output leads.
