TEST ELECTRONICS’ TE-10,000
High Voltage Surge Current Monitor
For simultaneous surge testing: transformers, inductors,
and other magnetic windings
TE-10,000 SCM
Order # TE-10,000 SCM
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..
Top Polycarbonate Shielded Test Surface
The top of the surge current monitor 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, the short lead lenths eliminate test lead
ringing, which minimizing RF noise emission, and false scope triggering. This results in
extremely accurate tests.
Safety Features
- Top of the unit doubles as a safe insulated testing area.
- Polycarbonate cover protects the operator from flying debris.
- Tinted cover prevents blinding flashes.
- Magnetic reed switch safety interlock disables all power to the test terminals when the cover is lifted.
- These safety features make it nearly impossible to touch the HV parts unintentionally.

Easily Upgraded for Different Applications
The Surge Current Monitor's internal circuitry consists of an array of torroidal current
transformers. When the current transformer outputs a pulse higher in amplitude than the
reference setting on it's associated operational amplifier, the LED lights, showing a
failure. This reference value is adjustable to meet the needs of mostly every application.
