MULTICHANNEL HIPOT TESTER
MODEL 19020 SERIES

High Eciency Hipot Test Solution

Hipot test is one of the major test items in electrical
safety test. All electrical components and products
including transformers, capacitors, power supplies,
chargers and home appliances all require Hipot
test.

Wi th more tha n 2 5 ye ars of ex pe ri en ce in
de vel o p i ng t h e i n st ru me nts fo r t es t an d
measurement, Chroma creates the 19020 multi­channel Hipot tester with a brand new architecture.
It can measure the Hipot leakage current of all
channels at the same time and conduct tests on
100 DUTs maximum simultaneously.

There is no need to purchase various Hipot testers
to save the production line space. I ts one time
multi -c hannel tes t can increase the eff iciency
of e le ctrica l re gul atory test . It i mpr ov es t he
productivity and reduces the risk of test for the
products that require Hipot test only.

Chrom a 190 20 also has powe rful func tion s in
Fla shover detection and Open/S hort Check . It
contains several international patents and is the
best tool for electrical regulatory Hipot test as not
only reliable quality can be obtained, but highly
ecient test platform can also be created.

World's First Sync Hipot Test
(Patent Registered)

Chroma 19020 has equipped wit h the world 's
firs t sync Hi pot test functio n that on e single
unit can perform 10 channels sync output and
measurements simultaneously. Maximum 10 units
(master & slave) can be controlled to have 100
channels in total. They can be grouped for output
to avoid creating voltage dierence due to adjacent
tests as well as to improve the productivity.

Applications

Chroma 19020 can be applied to various electrical
products for time consuming tests such as quality
assurance sampling test and production line test.

SYNCHRONOUS HI-POT TEST

The issue frequently encountered when testing multiple DUTs for Hipot is unable to synchronize the voltage output. When planning for production line or

automation, minimized facility and optimized space are often utilized in the plant; therefore, the distance between two DUTs is usually very short. Taking the

output voltage 5kVac for example, when the output of Hipot tester is not synchronized, the two DUTs may create a discharge of high voltage dierence (up

to14kV peak-peak) and cause the xture to be damaged and erroneous judgment. Chroma 19020 synchronizes the output signal so there is no high voltage

dierence on the adjacent two ends that not only can extend the life of production equipment but also reduce the occurrence of misjudgment.

FLASHOVER DETECTION

Same as other Chroma EST Series, 19020 has Flashover detection function. Flashover is the electrical discharge generated by high electric eld inside or on the

surface of insulation material that makes the DUT to lose its insulation characteristic and form a transient or discontinuous discharge. It can cause a carbonized

conductive path or damage the product under test. Flashover cannot be detected by monitoring leakage current only. The change rates of test voltage or

leakage current are monitored to detect ashover as its detection is one of the most indispensable test items for electrical safety test.

OPEN / SHORT CHECK (OSC)

OSC function can check if there is any Open (bad connection) or Short (DUT short circuited) occurred during test. If a DUT is open circuit during test, the unit
might be misjudged as a good one. If a DUT has short circuit, OSC function can lter it out to diminish the damage to xture and save the test cost.

In general, products under Hi-pot test have capacitance (CX). CX could be tens of pF to several μF in normal condition. When the circuit connection is
interrupted, a small capacitance (Cc in Figure 6) will be formed on the broken interface that is usually lower than 10pF. It makes the entire capacitance of the
product lower than normal value. The capacitance of a product may be higher than normal when the product is short-circuited or near short circuit. Thus the
high/low limit of capacitance variation can be used to identify the short circuit problem.

Chroma 19020 can be applied to test various electrical parts and

products. The multi-channel Hipot tester can test multiple DUTs at

once. The applications include:

• Automation of power cord and related cable material

• Automation of capacitor and resistance

• Insulation test of switch and connector

• One time test for transformer with multiple pins or multiple units

• Production planning for charger and adapter

With 190201 3-CH scanner, 19020 can finish 3 Hipot tests at once.

Taking a two winding transformer as an example, the following three

Hipot tests can be done at one time within a DUT loading time.

1. Primary to Secondary Hipot test.

2. Primary to Core Hipot test

3. Secondary to Core Hipot test.

This application can be applied to transformer, power adapt er,

common mode choke and so forth.

For different test solutions, Chroma has accessories and fixtures

available for use. Please contact local service for further information.
