Features
The HTT-1R was designed to provide a fast, safe and reliable way to
verify proper operation of Dielectric Withstand (hipot) and Ground Bond
Testers between calibration cycles, using actual component values which
mimic the product being tested. It provides a stringent periodic check
of your production line hipot and ground bond testers as required by TUV
and others. The HTT-1R functions like our successful HTT-1 tester, but
goes a step further by providing component values as the test loads,
instead of opens and shorts provided by the HTT-1.
By choosing one of our standard configurations conforming to
your testing parameters (or custom parameters based on your
requirements), the hipot and ground bond tester in use are checked by
realistic component values which mimic the characteristics of your
production items.
The HTT-1R verifies the result of the three failure modes
encountered in production hipot and ground circuit testing (open ground,
high leakage current, and dielectric breakdown) separately or in any
combination to verify proper test equipment operation. A passing test
can also be simulated.
The HTT-1R is designed to test up to 30A ground bond testers
using these values to simulate actual operation. Connections to the
Ground Bond Tester will add approximately 0.03Ω to these values.
GROUND BOND PASS: 0.025Ω
GROUND BOND FAIL: 0.1Ω
The HTT-1R also tests the leakage current trip function of the
hipot tester up to 3000V using one of four standard values. All
voltages are RMS Values, which are the values shown on the AC or DC
range of the hipot tester.
LomA: LEAKAGE CURRENT PASS: 0.5mA at 2100V / 0.35mA at 1500V
LomA; LEAKAGE CURRENT FAIL: 1mA at 2100V / 0.71 mA at 1500V
MedmA: LEAKAGE CURRENT PASS: 2.5mA at 2100V / 1.8mA at 1500V
MedmA: LEAKAGE CURRENT FAIL: 5mA at 2100V / 3.5mA at 1500V
HimA: LEAKAGE CURRENT PASS: 5mA at 2100V / 3.6mA at 1500V
HimA: LEAKAGE CURRENT FAIL: 10.5mA at 2100V / 7.5mA at 1500V
ExmA: LEAKAGE CURRENT PASS: 7.1mA at 2100V / 5mA at 1500V
ExmA: LEAKAGE CURRENT FAIL: 17.5mA at 2100V, 12.5mA at 1500V
The HTT-1R also tests the Arc Detection circuit of the hipot tester. The arc circuit is rated at 3000V maximum.
ARC CIRCUIT PASS: Open circuit
ARC CIRCUIT FAIL: arc-over at 750V ± 400Vac / 1050V ± 560Vdc
The HTT-1R is provided with test leads which allow
connection to any brand hipot tester which uses a standard NEMA 15A
receptacle and banana plug return leads to connect to the EUT. The
manual contains anticipated results and suggests testing procedures.
Custom configurations for various leakage current pass/fail points are available. Consult factory for price and delivery.
Provided with ANSI Z.540 Calibration Certificate, test leads and manual.
The stock HTT-1R simulates the following failures:
- Ground Continuity Chassis to Ground (Depending of model), and/or
- High Leakage Line to Ground (Depending of model), and/or
- Dielectric Withstand Failure (Arc View window displays an arc at 750Vac ± 200V).
The HTT-1R can also be set to simulate passing tests:
- Ground Continuity Chassis to Ground (Depending of model), and/or
- Normal Leakage Line to Ground (Depending of model), and /or
- Dielectric Withstand OK (up to 3000 volts)
*Custom Configurations allow you to specify:
- Ground Continuity Pass and Fail Levels (.1-5 ohms).
- High Voltage Leakage Limits Pass and Fail (10uA to 5mA at a user-specified voltage).
Works with any manufacturer's Dielectric Withstand or Ground
Continuity Tester. The HTT-1R simulates the failures and your tester
should return results consistent with the switch settings on the front
panel of the HTT-1R
The HTT-1R is a passive device. No batteries or power is required
