High Voltage Surge Tester
PN# 10000HVST
The most important features of the surge tester are its ability to test the entire winding insulation system. A high voltage surge generates turn to turn, coil to coil, and phase to phase voltage stress, as well as ground insulation stress. When used as a dielectric test, accurate voltage readings are essential. The HV Surge Tester monitors the voltage directly across the winding under test. This voltage is displayed on an oscilloscope and recorded on the Pass/ Fail LED latch monitor. This voltage will be accurate despite the impedance of the winding being tested. The insulation system can be tested way above the operating voltage because of the brief duration of the applied voltage test pulse. This allows faults to be detected long before they become apparent at operating conditions.
- Digital Voltage metering and a feedback regulated high frequency switching power
supply gives precise voltage control, and high power in a compact package.
- An internal 120V or 240V 60Hz power supply is provided. This power supply
voltage is used to power up the unit under test. The surge voltage is then
superimposed on top of this providing power on surge testing.
- AC input jack for superimposing any AC signal from 0-600VAC 50-500HZ on the HV
output. Used for High line, low line surge testing.
- Internal 1000:1 divider oscilloscope monitor jack simplifies monitoring the
pulse with a storage scope by eliminating the need for a big cumbersome HV scope
probe.
- The top of the surge tester doubles as a safe insulated testing area. This
innovative design saves bench space, costly safety equipment, and eliminates
those dangerous high voltage test leads. Above all, it eliminates test lead
ringing, minimizing RF noise emission, and false scope triggering. Resulting in
extremely accurate test results.
Easily Upgraded for Various Applications
The Surge Tester's internal circuitry consists of a back plane interconnecting
6 modular plug in wave shaping and signal processing boards.
These boards are readily available and may be easily swapped to generate almost any surge wave form.
The default internal power supply voltage may be changed simply by swapping the power supply board.

Computer Controlled Testing
The surge tester uses the standard RS232 serial interface for computer
controlled testing. The write function initializes a surge while the read
function monitors the Pass/ Fail indicator. Also, a D-A converter can be used to
adjust the surge voltage level. The computer controlled testing will greatly
reduce production time when multiple surge testing and variable surge voltages
are required. Safety Features
- Top of the unit doubles as a safe insulated testing area, saving bench space.
- Polycarbonate cover protects the operator from flying debris.
- Tinted cover prevents blinding flashes.
- Magnetic reed switch safety interlock blocks the surge pulse when the cover is lifted.

HVSCM- High Voltage Surge Current MonitorFor simultaneous surge testing magnetics Also available in rack mount
Designed to be used with the Model HVST High Voltage Surge tester. The Surge Current Monitor allows simultaneously surge testing 20 units. The Surge Current Monitor monitors the current going through each unit under test at the time of the surge. If a unit under test breaks down or leaks, the Surge Current Monitor will identify the bad unit by lighting the corresponding LED. The most important features of the surge tester are its ability to test the entire winding insulation system. A high voltage surge generates turn to turn, coil to coil, and phase to phase voltage stress, as well as ground insulation stress. When used as a dielectric test, accurate voltage readings are essential. The HV Surge Tester monitors the voltage directly across the winding under test. In production testing we expect that most of the time the devices will pass. In the event that one should fail, the failed device would be removed and then all the parts would have ot undergo another surge test. Since most devices pass most of the time, simultaneous surge testing can be a real time saver.. 
300VAC- Regulated Variable 0-300VAC Power SupplyFor convienient desk top and bench top use Also available in rack mount
The most important features of the power supply is its ability to hold a constant voltage as the power lines fluxuate and the load fluctuates. Used for testing testing high and low line conditions for any AC powered device.
