AC DIELECTRIC TEST SYSTEM

The AC test transformers are especially designed for

medium capacitance testing object, such as power

transformers, cables, generators, motors, GIS

switchgears, bushings and arresters. It’s particularly

suited for tests requiring stable voltage even if the

load changes under voltage (corona, wet and

pollution tests) or when the load is inductive

(inductive voltage transformers).(inductive voltage transformers).

The possibility of stacking several of these

transformer modules allows reaching very high

voltage levels by keeping reasonable floor space. We

have successfully experienced 2250kV 4500kVA test

transformer by three module cascaded.

Tank type AC test transformer is situated in an

enclosed and earthed metal tank. This transformer is

oil-cooled and can be optionally equipped with a

suitable bushing (oil to air or oil to SF6). It’s also

qualified for continuous duty, long duration tests.

TheThe capacity of tank type test transformer is larger

than cylinder type, it can be used for high voltage

pollution tests, test line and capacity required

continuous test. This design is most suitable for

using outdoor, and therefore is recommended to use

in areas with poor climatic conditions, especially in

high humidity areas and tropical countries.

AC TEST TRANSFORMER

SF6 gas insulated test transformers are especially

designed for testing metal-clad switchgear (GIS) in

the factory and on-site, and for testing on-site

substation equipment. The conventional

transformer can be flanged directly to the GIS. This

makes testing of such installations possible

without feeding them through an air-SF6 bushing.

ThereforeTherefore the merits of the encapsulation remain

effective also during the test which is essential for

PD tests. These systems are particularly suited for

on-site tests of GIS after assembly. In the factory,

they allow to test sub-assemblies and components

directly in the manufacturing line, thus avoiding

transportation to a central test facility, and extra

handling.handling.

Portable test transformer are small volume, light weight, with compact structure and

multiple function, general purpose and easy to use. YDJ series is oil insulated, YDQ series is

SF6 gas insulated, GTB series is dry type, single voltage upto 150kV.

AC RESONANCE TEST SYSTEM

Adjustable inductance resonant test system is

designed to compensate capacitance in the

testing circuit precisely by tuning inductance of

the test system. The natural resonance frequency

of the test system matches feed-in mains, usually

50/60Hz. When the test system gets in resonance,

it generates continuous testing high voltage.

ItIt offers significant advantages to standard AC

test systems where the load is largely capacitive

with low loss such as power cables, GIS

switchgears, generator windings, motors,

transformers and dry testing of insulator strings.


Variable frequency resonant test system vary

the output frequency to tune the system to the

load capacitance creating a resonant circuit.

And the output frequency is typically in the

range of 20 to 300Hz. It is ideal for

commissioning tests of power cable and

GIS/GIL.

ComparedCompared to conventional AC test transformer,

the relatively low testing power required, and

the ability to make a direct comparison of the

factory and field tests, favors the variable

frequency resonant test system as the most

practical on-site test system.

SERIES RESONANT EQUIPMENT

Tank type AC series resonant test system is

special designed for the high capacitance load,

such as power cable. The huge system is suitable

for testing in the factory or on-site. There are two

different design: variable frequency or adjustable

inductance.

It’sIt’s widely used for MV capacitor testing, power

cable aging test, motor/generator testing and

other high power products testing.

ItsIts on-site testing system is movable and special

suitable for long distance paved power cable field

testing. The whole system are fixed on the truck (8

meters – 14 meters length, 2.5 meters width), the

truck can connected in series or parallel.

SF6 gas insulated series resonant test system is

special designed for testing of gas insulation

switchgear and gas insulation substations. The

system can be connected with the GIS directly,

which bring great convenient to the testing.

ComparedCompared to oil insulated resonant system, It has

the advantages of very low partial discharge

level, light weight, small volume and movable.

There are two different design: 30-200Hz

variable frequency or 50/60Hz adjustable

inductance.
