KHA3000
Overview of the Product
This product can measure harmonics current, flicker, or voltage fluctuations. It can execute
tests that conform to IEC and JIS standards, in combination with the AC Power Supply and
Line Impedance Network.
This product displays measured values in various display modes in real time. It can make
evaluations, pass/failure decisions, and analyses by conformance test.
Because the AC power supply
1
can be controlled from this product, a test system can be
configured without a PC being used. This product can also be used independently as a power
analyzer.
Features
●
A test system can be configured without using a PC.
A harmonic current and voltage fluctuation test system can be configured without a
computer being used. The AC Power Supply
1
used for the test can be controlled.
●
Single-phase and three-phase circuits can be handled.
Single-phase and three-phase equipment can be tested with three-channel input. Wire
connections are simple because phase voltage measurement and line voltage
measurement can be switched by internal circuits.
●
Pass/failure decision for standards conformance
The cause of a problem identified by pass/failure decision can be investigated by the
analytic function.
●
Measured values are displayed in real time.
Measured values are displayed in real time and the status of the EUT can be displayed.
The margin ratios to limit values can be known in real time. Waveform measurement is
possible.
●
Compliant with the latest standards
This product supports the EN, IEC, and JIS standards, and can be upgraded to
accommodate future revisions of the standards. The product is compliant with measuring
technique standard IEC 61000-4-7 Ed2.1 and IEC 61000-4-7 Ed2.0 that measures
interharmonic waves and handles them as harmonic groups and IEC 61000-4-7 Ed1.0
that permits continuous use.
1. There are restrictions on the use of the following AC power sources.
・
PCR-WE
This product cannot directly control PCR-WE. To use PCR-WE, the separately sold
application software SD006-KHA Harmonics Analyzing Suite is required.
PCR-WE cannot be combined with a standard line impedance network. For the line
impedance network for PCR-WE, contact your Kikusui distributor or agent.
・
PCR-LA
PCR-LA with firmware version 3.32 or 3.33 cannot be used.
