1,000 A Power & Multimeter Clamp

The F407 clamp is ideal for low-voltage, medium-power systems in LV electricity production and distribution, industry, railways, etc. It is also suitable for lift/elevator technicians and other lifting and transport equipment specialists. Maintenance, testing, monitoring, diagnostics and connection are the main applications for the clamps in this series.

Equipped with a fast 12-bit TRMS digital acquisition system, F407 clamps offer particularly accurate measurements. Due to their large bandwidth and high crest factor, these clamps guarantee accurate measurements whatever the type of signal. Automatic AC/DC detection is a standard feature on all the models in this range, as is IP54 protection. The large backlit 10,000-count display makes it easy to read in all circumstances. The fact that each rotary-switch position corresponds to a single function means that it is simple to use.

Specs :

• Current: 1,000 AAC / 1,500 ADC
• AC and DC voltage up to 1,000 V
• Power values: W/VA/var, PF & DPF
• THD-f & THD-r
• Harmonics up to 25th order

Webinar 3 – Chauvin Arnoux- Low Resistance Measurement – March 2022 (March 24th 7pm, March 25th 10am)

In this webinar we will look in detail at the methods of carrying out low resistance measurement. When installing and testing power systems, such a bus bars, it is essential that we have very good electrical connections to avoid local heating, volts drop and many other effects. Using micro-ohmmeters to measure these very low resistance values is a simple and effective way to ensure reliable connections.

This webinar will cover:

•	Introduction to low resistance measurement
•	Factors that affect the accuracy of low resistance measurement
•	Applications that require low resistance measurement to be carried out
•	Selection of suitable devices to measure low resistances.

Brand New & Available to order now.

Chauvin Arnoux UK are pleased to announce the launch of the latest in our Qualistar family, the CA8345.

The latest model is fully compliant with IEC 61000-4-30 Class A.

Intended for inspection and maintenance teams on industrial or tertiary installations, the Qualistar gives you a snapshot of the main electrical network quality features. Comfortable to handle and equipped with an intuitive GUI, these analysers offer high measurement accuracy. They also feature numerous calculated values ​​and several processing functions.

The CA 8345 is a Class A Qualistar power and energy quality analyser.
Like the Qualistar+ models, it is equipped with an intuitive HMI and remains simple to use. Multilingual online help can be displayed at any time on the large color LCD touch screen.
Easy to handle, it is intended for inspection and maintenance teams working on industrial or tertiary installations. It can be used to obtain a snapshot of the electrical network's main quality features. The Qualistar model scan be used on all types of installations.
For greater safety, the CA 8345 automatically recognizes the type of current sensor connected.
The CA 8345 ensures high measurement accuracy.It provides a large number of calculated values ​​and several processing functions. It offers users all the measurements needed to successfully handle energy efficiency projects and monitor the electrical distribution network. By calculating the cost of the electricity, you can immediately determine the value of the electricity consumed.

It can display the harmonics and interharmonics as stipulated by IEC 61000-4-7.
At the same time, it detects the carrier currents flowing on the installation.

The CA 8345 monitors all the events on the network:

• Trend diagram, variations of the signal parameters
• Parameterizable alarms, with the possibility of sending an email alert to the user
• 2.5 µs transient
• 12 kV shockwaves lasting 500 ns
• TrueInrush to capture all the load start-ups….

A Monitoring mode can be used to record the measurement campaigns required for analysis as per EN50160.

Communication

In addition to the SD and USB drive, it is also possible to recover the measurements and communicate with the CA 8345 remotely. USB, remote links, Wifi (direct or via server) or via RJ45. An IRD Server mode allows extraction of the data from anywhere in the world without endangering internet security.

The Power Analyzer Transfer software can be used to process the measurements made with the Qualistar Class A.
The  PAT3 software  can be downloaded from our Support website.

Introduction to Insulation Resistance Testing- June 2022 (June 9th 7pm & June 10th 10am)

Insulation is arguably the most important component of all electrical circuits and equipment, this is certainly true from a safety perspective. The testing of insulation is critical to assessing the condition of all electrical systems. From PAT testing your kettle or carrying out an EICR on an electrical installation to checking the windings on an HV supply transformer, insulation resistance testing is a key test relied on by electricians every single day. These webinars give you a detailed look at the topic of insulation resistance testing across a range of applications. If you are an electrician, then these webinars are must see viewing.

• What is insulation and how it is tested
• Typical insulation test applications and test voltages
• Insulation resistance testing in BS7671 Amendment 2
• Test equipment selection ≤1000V
