Hipot Tester Description

The Chroma Guardian 19050 series Hipot Tester is comprised of three models. The Guardian 19052 is capable of AC/DC/IR Hipot testing and insulation resistance (IR) measurements. The Guardian 19053 combines both AC and DC Hipot tests and IR measurements with 8HV scan channel capabilities. The Guardian 19054 combines both AC and DC Hipot tests and IR measurements with 4HV scan channel capabilities. Front panel operation, digital display, and user friendly controls allow test parameters and limits to be set easily without high voltage activation.

Open Short Check (OSC)

The O.S.C function is used to check whether the connection is open, or a short circuit, between the instrument and DUT (device under test) before the Electrical Safety Test is performed. If the connection is bad between the instrument and DUT, like bad leads or relay oxidation, the test may reult in a PASS determination. In some cases, the DUT has a short before testing. Testing continually leads to instrumentation damage due it suffering the high load current. Therefore, we check for the open and short circuit to ensure the test is effective and to protect the instruments.

Generally, DUT have a capacitive load (Cx) from tens to thousands of pF. If the connection is open, a capacitance will appear and then total capacitive load is lower than that of normal conditions. If the DUT is shorting, the total capacitive load is higher than that of normal conditions. Therefore, we can measure the value of the capactive load to verify that the contact is good or not.

Hipot Tester Circuit Open/Shorted

 

Ground Continuity Check

All of the 19050 series testers have a ground continuity check feature to determine the resistance between the ground blade of the power cord and any exposed metal on the product. This resistance should be less than 1Ω.

 

Ground Fault Interrupt (GFI)

A requirement for test environments indicates that test equipment be equipped with auto interrupt device. Chroma builds in a Ground Fault Interrupt (GFI) function for this purpose. When the current meter A1 and A2 detect a difference (i2-i1=iH) between the value i1 and actual i2 test current over high, this device can cut the power transiently for protection of the operator. It is not only compliant with the safety standard but also provides additional safeguards for test personnel.

Load Boxes are used to verify Hipots are passing and failing when they should be. Verification tests are commonly run at the beginning of each shift, day, or week depending on production requirements. This box is built with resistors of your choosing so you don’t have to change your test paramaters.

HV Retracting Probe
A190344

An alternative test lead option that may be desired based on your application

Dual Switch Fixture (for A190512)
A190354

This option for the A190512 saves time by switching in between fixtures. After fixture A is tested you can switch to fixture B and run through that test sequence while removing and installing a new DUT on the A side.

GPIB Interface
A190508

Optional PC communication interface that may be preferable over the standard RS-232.

Pneumatic Scan Box (Model 19053 only)
A190512

This scan box is able to conduct low voltage and high voltage tests on the DUT at the same time to save manpower and increase productivity. It interfaces with a 19053 for the high voltage test and with an LCR Meter for a low voltage test. Ask us about our LCR Meters.

A190517 – 19″ Rack Mount Kit [19050/19572]
A190517

19″ rack mount kit for the 19050 series of hipot testers and 19572 ground bond tester.

Remote Test Box
A190701

Allows you to remotely run your tests to keep operators away from the front panel output.

40kV Test Probe
A190702

An alternative test lead option that may be desired based on your application.

Remote Foot Switch
A190704

Allows you to initiate a test remotely to keep operators away from the front panel output.

ARC Verification Fixture
A190708

ARC Verification Fixture for 19050/19070/19570 Series. Used to verify the ARC Detect feature on your hipot is functioning properly.

Corded Product Adapter Box (115V)
G13

This internally shorts line and neutral, and plugs into the HV output. If your DUT is terminated with a line cord you can plug into this box to make your testing easy.

Clip Lead Set: HV and Return
S02_S04_S02-02

3 ft. (S02) cables come standard with the purchase of a 19052, 19053 or 19054. Also available in 6 ft. (S04) and 12 ft. (S02-02)

Unterminated HV leads
S09_S10_630215

3 ft. (S09) cables come standard with the purchase of a 19053 (quantity 8) or 19054 (quantity 4). Also available in 6 ft. (S10) and 12 ft. (630215)

Multi-resistor Load Box
S12

Load Boxes are used to verify Hipots are performing properly. Verification tests are commonly run at the beginning of each shift, day, or week depending on production requirements. This box is built with resistors of your choosing so you don’t have to change your test paramaters.
