The new generation of IEC 61000-4-30 Ed.3 compliant power quality monitors

Prevent power quality problems with LINAX PQ3000


Power quality monitoring often only gets talked about when there are disturbances, for plant malfunctions, device failures, process interruptions, data losses, IT failures or even an electrical power blackout. These types of failure are usually very time-consuming because the cause is not always immediately detected. In addition, breakdowns are always associated with avoidable costs. So continuous preventive monitoring of the mains with the LINAX PQ3000 from Camille Bauer Metrawatt AG produces a direct pay-off.

The PQ3000 helps to detect problems in the mains supply before any financial damages or personal injuries are suffered. It generates data that assists in identifying the cause of failure as soon as an event occurs. It is rated as a Class A device and measures the power quality in compliance with IEC 61000-4-30 Ed.3. Certified compliance of the PQ3000 to all standards is guaranteed by an authorised test lab. This means that reliable and comparable data and information resulting from its measurements can be provided to regulation authorities, used in negotiations with energy suppliers, or for internal quality control. An EN 50160 voltage quality standard compliance report can also be generated in order to audit the quality agreed between the energy supplier and the consumer.

The PQ3000 from Camille Bauer Metrawatt AG can be freely parametrised using either the display or a web browser. It captures periodic data as well as PQ-related events. The PQ3000 performs extremely reliable measurement of normative parameters, such as mains frequency, flicker, supply asymmetry, harmonics, interharmonics, voltage dips, voltage swells and voltage interruptions. The PQ3000 also provides configurable digital inputs as well as analogue, digital and relay outputs. These can be used for example, for alarm signals, counters, status logs etc. Long-term recordings spanning several years using the datalogger are no problem for the PQ3000. An optional UPS can prevent unwanted data loss when a voltage event occurs. The PQ3000 can be connected via Modbus to a higher-level system (SCADA, for example) or to an industrial Energy Management System (for example SMARTCOLLECT from Camille Bauer Metrawatt AG) which creates extra added value.

The LINAX PQ3000 is one of the first devices on the market which is not only capable of capturing ripple control signals as required by the IEC 61000-4-30 Ed.3 standard, but also of recording them as an event for a defined period of up to two minutes. This makes it possible to check at any time (to control a consumer for example or to switch tariffs) and determine if the ripple control level and the pulse sequences are in the expected range. This can be done directly on the device or through the web interface.
