Webinar : Tmetrix and Hioki -Leakage Current Measurement Testing

Description In this webinar, Hioki will present the basics of current leak testing and will give a special consideration to current leak testing of medical devices. Current leak requirements for medical devices are much more stringent than for commercial devices since the device often come into direct contact with the patients and healthcare workers. For medical devices such as ventilators, leakage current must not exceed a defined threshold for a variety of electrical fault conditions.

To meet these challenges, Hioki developed a suite of test instruments and management software, and attendees will learn about the patented technologies that enable users to preform medical leakage current tests faster and more reliable than with the competing products.

Application: Operational Testing of Multiple-circuit Protective Relays

Protective equipment at power plants and electrical substations detect earth faults and lightning strikes and issue instruction signals to circuit breakers for them to trip when the situation calls for it. For this reason, equipment such as protective relays must be regularly maintained and ready to serve when needed.
Maintenance work includes the verification of correct operation, which can be done using a data acquisition device or waveform recorder that can simultaneously measure control and operating signals for multiple circuits. DAQs also capture operating signal timing while using a command signal as the reference.
As protective equipment become more complex, so do the number of control circuits, and a measuring instrument that can capture data from multiple channels is indispensable.  The Hioki MR8827 Memory HiCorder presents a solution by delivering the following benefits:
  • High-speed, simultaneous sampling across multiple channels
  • Maximum 32 analog + 32 logic channels
  • Capture signals from multiple circuits with voltages ranging from high to low

Gauss Instruments’ EMI64k Automation Software: Fully Automated Emissions Measurements

Gauss Instruments’ TDEMI family of EMI receivers provides an expansive, fully CISPR-compliant, real-time bandwidth that allows you to dramatically—and simultaneously— accelerate your measurements and reduce measurement uncertainty. By using Gauss Instruments’ full automation software suite EMI164k, test procedures can be configured in accordance with the CISPR 16-2-3 standard for FFT-based measuring instruments. Compared to previous pre-scan and final measurement strategies, this greatly increases overall test quality—and reduces test times by orders of magnitude.

Previously, pre-scan and final scan test procedures were performed to reduce overall test times. Today, Gauss Instruments’ offers a novel real-time scanning feature for the TDEMI X test receiver series that provides a real-time bandwidth spanning several Gigahertz, allowing final optimization to be performed at all frequencies—simultaneously, in just one step.

With a newly designed, very powerful hardware module, such measurements across several Gigahertz can be done in the real-time spectrum analyzer mode. In the 1-18 GHz frequency range all frequency points can be directly measured at a very high resolution in time and the results can be optimized instantly.

Over the entire frequency range the results are displayed in real time. Detectors’ peak, average and RMS are all available in this mode. What’s more, video bandwidths required in accordance with the standards can be applied. Of course, all measurements in accordance with the standards CISPR 16-1-1 MIL 461 and DO 160, as well as many other national and international standards, are fully covered.

Automated Emissions Measurements

EMI64 graphical user interface

For the first time, a typical measurement in the 1-18 GHz range can be scanned in real time by testing with Gauss Instruments’ TDEMI X receiver. The DUT is rotated in just one continuous movement and the angular position and the maximum level of emission are recorded. All requirements of CISPR 16-2-3, ANSI and FCC standards are met by the TDEMI X receiver.

Automated Emissions Measurements_1

Full 3D radiation pattern of the DUT

The upshot of all this is that EMC testing can now be more sustainable. For example, it is now possible to create an entire database and documentation with radiation patterns, test procedures and casing construction, as well as with much more information. Newly developed products and designs can be tested right from the beginning to make sure all required limits are met. This allows you to reduce the time and money you spend in the development, design and final market certification processes.

The EMI164k is not limited to CISPR applications. It also performs measurements in accordance with FCC and ANSI, or MIL-461 and DO-160 standards!

The TDEMI receiver family is ideal for all kinds of tests and applications, starting with pre-compliance, ultra-compact and mobile receivers right up to high-end EMI test solutions with up to 685 MHz real-time bandwidth and 40 GHz real-time scanning—all with the lowest noise floor available in the receiver and real-time analyzer market.

Thanks to the modular architecture of Gauss Instruments’ TDEMI EMI receivers, as well as the EMI164k automation software suite, ACA TMetrix can provide an optimized, cost-effective software solution tailored to your requirements.

HIOKI Launches Power Quality Analyzer PQ3198

HIOKI Launches Power Quality Analyzer PQ3198

Revamped Functionality and Specs Simplify Recording and Analysis of Power Supply Issues

New instrument eliminates the need for a dedicated sensor power supply while enabling power and efficiency measurement of two circuits
March 14, 2019 – Nagano, Japan
HIOKI Launches Power Quality Analyzer PQ3198

                PQ3198 Power Quality Analyzer

HIOKI is pleased to announce the launch of the Power Quality Analyzer PQ3198, a new instrument that revamps the functionality and specifications of its predecessor, the Power Quality Analyzer PW3198. The product makes it even easier to record and analyze power supply issues, including by eliminating the need for a dedicated sensor power supply and by enabling power and efficiency measurement of two circuits.

■ Development Background
As power circuits become more complex with increasing use of power electronics devices, large equipment, and geographically dispersed power supplies, power supply issues in the form of electronic device malfunctions and failures are becoming more common.

HIOKI Launches Power Quality Analyzer PQ3198

Power quality analyzers are measuring instruments that record and analyze power supply quality in order to investigate the causes of those and similar issues in the field. Since launching the Power Quality Analyzer 3196 in 2001, HIOKI has developed a series of increasingly sophisticated products for the product line to accommodate customer needs while helping them resolve numerous power supply issues around the world.
HIOKI’s line of power quality analyzers currently consists of the mid-range PQ3100, launched in October 2016, and the flagship PW3198, launched in April 2011. Those instruments are paired with voltage cords and current sensors that measure voltage and current, respectively, and some of the latter require a separate, dedicated power supply. After HIOKI added functionality for powering current sensors to the PQ3100, there was increasing demand from customers to do the same for the flagship PW3198, which led HIOKI to redesign the model.

   Solar power system

■ Principal New Functionality  
1. Ability to supply power to sensors, eliminating the need for a dedicated power supply
The PQ3198 can supply power to AC flexible sensors*1 and AC/DC sensors*2, eliminating the need to provide a separate, dedicated power supply for those devices as they have required in the past. In addition to making it possible to use the instrument in outdoor locations where power is not readily available, this capability makes it easier to work in confined locations by reducing the number of wires needed to make measurements.

2. Ability to measure power and efficiency on two circuits
The PQ3198 can simultaneously measure power and efficiency on two circuits, for example in the primary (input) side and secondary (output) side of an EV rapid charger’s AC/DC converter or a solar power system.
The instrument can also measure DC to AC inverters with a fundamental frequency of 40 to 70 Hz and a carrier frequency*3 of 20 kHz or less.3. Remote measurement using FTP server functionality
The PQ3198 provides an FTP server function, making it easy to acquire data from the instrument remotely.4. Extended recording without the need to worry about the number of events (power anomalies)
Whereas the previous model (the PW3198) was able to record a maximum of 1000 events, the PQ3198 boosts that number to 9999. Further, it can record continuously for up to 366 days based on repeat recording settings.5. Standard support for analysis with PQ ONE analytical software
The PQ3198 ships with PQ ONE, a popular analytical software package that also comes with the Power Quality Analyzer PQ3100. Functionality includes display of event statistics (to display events by date or time of day), EN50160 judgment (for evaluation, analysis, and judgment capability that complies with the EN50160 standard), and report generation.

■ Principal Markets
Management of power quality and analysis of power supply issues by power companies, electricians, electrical maintenance engineers, building maintenance companies, electrical safety associations, and equipment end-users*1 AC flexible sensor: A loop-shaped AC sensor that can be bent freely. Used to measure wires with a large diameter and large currents. In the context of the PQ3198, “AC flexible sensors” refers to the AC Flexible Current Sensor CT7044/CT7045/CT7046.
*2: AC/DC sensor: A sensor that can measure either alternating or direct current. In the context of the PQ3198, “AC/DC sensors” refers to the AC/DC Auto Zero Current Sensor CT7731/CT7736/CT7742.
