DTMG High Voltage Hipot Tester
The DTMG is a high voltage hipot tester which controls transformers up to 50kV AC and/or DC.
The DTMG is available as either a single rack unit, 2 element rackable unit or separated units (control on one side and transormer on the other) according to the main european standards
Typical applications include use in test laboratories, production lines and high speed production lines for testing cables, capacitors, motors, electrical modules, switchgear, insulation materials, connectors, relays, transformers, bushings, fuses and arrestors to comply with the 60060 standard.

Technical Specification
DIELECTRIC STRENGTH TEST FUNCTION
Output voltage
-
1 kV to Umax AC (50 or 60Hz - to be specified when ordered)
-
Accuracy : ± (2.5% + 1U) of the reading voltage (1U=1% of the full scale), with the detection modes : DI, IMAX or DI+IMAX. Voltage regulation is made by an internal varistat.
Voltage reading
- On a digital kilovoltmeter connected on the output terminals
- Accuracy : ± (1.5% + 1U) of the displayed voltage (1U=1% of the full scale)
- Display : 3 digits (example : 25.0 kV)
- Resolution : 3 digits (example : 250 points for Umax = 25.0 kV)
Stability
- Less than 3% for a mains variation of ± 10%
Current
- Short circuit : ± Pmax/Umax at the full scale (in AC voltage) for the max. voltage adjustment
Current reading
-
On a shunt resistor inserted in the test circuit
-
Accuracy : ± (2.5% + 2U) of the displayed voltage (1U=1% of the full scale)
-
Display : 3 digits (example : 9.99 mA)
-
Resolution : 3 digits (example : 999 points for Imax = 9.99 mA)
Breakdown detection
-
“DELTATEST” detector adjusted for DI = 10% of the full scale ± 10% with 10 μsec. ± 20%.
-
Total insensitivity to current due to the resistance and the capacitance of the device under test
-
“IMAX” detection by maximum current adjustable from 0 to Pmax/Umax in AC voltage by current steps of 1 digit (example: for 99.9 mA, steps are 0.1 mA, for 20.0 mA, steps are 0.1 mA)
-
DELTATEST and IMAX mode combination
Breakdown indication
-
By visual (LCD screen and LED) and sound signal
-
Breakdown voltage and current are stored on the LCD display
-
HV primary transformer shorted when the output voltage is switched off
IMIN threshold function
DC voltage option
Timer
-
Rise and fall time adjustment between 1 and 999 sec. in AC voltage
-
Hold time adjustment from 1 sec. up to 999 sec. in AC voltage (up to 60 hours with DTMGPro PC software)
-
Display : 3 digits (example : 999 sec)
