It provides real-time compliance judgments and can generate test reports without a PC. Integration with AC power supplies and line impedance networks is possible for comprehensive testing setups.
Operation: The operation flow includes setting test conditions, starting tests, analyzing results, and printing reports. The device supports easy upgrades to accommodate new standards and allows users to switch between old and new standards in real-time.
Measurement Capabilities: The KHA Series measures harmonic compliance for currents between 16A and 75A per phase and flicker compliance for voltage fluctuations. It provides detailed graphical and list displays of various parameters, including V/I waveforms, harmonic trends, and flicker values.
Additional Functions: The analyzer includes a quality check function for power supplies, supports repeatability checks, and allows for simultaneous three-phase measurements. It features user-friendly interfaces and terminals, with support for GPIB, RS232C, and USB connections.
Technical Specifications: The KHA Series supports a maximum input voltage of 600Vrms and current up to 40Arms. It offers various measurement functions, including voltage, current, power, and frequency, with high accuracy and resolution. The device is equipped with a rush current measurement capability and provides guidance on standards and technical terms through an assist function.
Measurement Functions: The device can analyze voltage harmonics up to the 40th order and includes flicker/voltage fluctuation analysis conforming to IEC standards.
Standards and Requirements: The device adheres to IEC 61000-3-3 and IEC 61000-3-11 standards for flicker analysis, and IEC 61000-4-15 for measuring instrument standards. It provides Pst accuracy of 1 ± 5% with measurement times ranging from 30 to 900 seconds.
General Measurement Functions: Includes current/voltage waveform monitoring, FFT analysis, and in-rush current measurement. Communication interfaces supported are GPIB, RS232C, and USB.
Data Storage and Control: Data can be stored on Compact Flash memory cards up to 512 MB or USB memory up to 16 GB. External equipment control is possible via PCR-LA control using RS232C.
Environmental Conditions: The device operates within a temperature range of 0℃ to 40℃ and humidity of 20%rh to 80%rh. It has a withstanding voltage of 1500VAC for AC input to chassis and 3550VAC for measuring terminal to chassis.
Safety and EMC: Complies with the Low Voltage Directive 2006/95/EC and EMC instruction 89/336/EEC. Accessories include a power cord, voltage sensing terminal plug, and operation manual.
Software Applications: The KHA3000 and KHA1000 models come with dedicated software for harmonic analysis, allowing test condition settings, execution, and data analysis. The software supports Windows operating systems and requires specific system configurations.
AC Power and Impedance Network: Specifications for the PCR-LA series AC power units and LIN40MA-PCR-L impedance network include output capacity, frequency range, and impedance values.
Accessories and Options: Various accessories are available, including multi-outlet units, rack mount brackets, and Ethernet ports. The OP02-KHAS device is used for daily checks of harmonic and flicker measurement systems.
Procedures: Setup procedures emphasize using appropriate wiring to minimize voltage drop and ensure accurate measurements, recommending thick cables (at least 8mm2) for connections exceeding 16A.
Calibration and Traceability: Calibration is conducted in compliance with ISO/IEC17025 standards, although KIKUSUI does not directly provide ISO/IEC17025 compliant calibration for the KHA1000/3000. Calibration data can be provided with an expression of uncertainty as a chargeable option.
Recommendations: For accurate harmonics measurement, it is advised to use the internal shunt resistor and clamp sensors, with a relative error margin of ±0.6%. Enabling Delta Transform for KHA3000 version 2.00 or higher is suggested.
Additional Information: The document includes contact information for distributors and notes on product specifications, which are subject to change. It also highlights the importance of using the equipment under qualified supervision.
