The UP-2210 unit is an advanced Power Quality meter


• The UP-2210 unit works as an advanced power quality meter and at the same time as a fault recorder. All of the power quality parameters can be analyzed in accordance with voltage quality standards such as the EN 50160 or national regulations such as the Swedish EIFS. The UP-2210 unit captures both steady state disturbances (harmonics, flicker etc.) as well as rapid voltage changes (sag/swell events and fast transients). The nodes in the PQ Secure system consist of UP-2210 meters.

• Advanced 3-phase Power Quality and Transient Monitor

• The UP-2210 is a full-featured, norm-compliant power quality monitor capable of detecting any disturbances encountered in a network.

About Power Quality 

Power quality is a generic term for disturbance-free electricity supply. Deviation from voltage sinusoidal waveform (50 Hz), which may result in equipment being disturbed or damaged, is to be regarded as a power quality disturbance. This means that the more sensitive equipment you connect to the grid, the higher should your demands on power quality and disturbance-free environment be. - Unipower AB

Power Multimeter with PQ Analyzer
The new, professional METRAHIT ENERGY multimeter is exceeding all previous performance limits.

The METRAHIT ENERGY is a digital multimeter with power and energy measurement, e.g. for ascertaining energy consumption values for consumer electronics, communications devices, information technology equipment and household appliances (e.g. refrigerators) during operation and in standby, and a single phase power quality analyzer for testing power quality and detecting power disturbances.


P211C: Fuse lead adapter with 8 ID rings

Fuse Lead Adapter 

This adapter adds flexibility to virtually any electrical test application as it fits in-series with existing test leads. Easily connecting inline with sheathed 4 mm banana plugs, the P211 extends safety by reducing risks associated with arc flashes. In the event of a current surge, its internal fast acting fuse will cut power in fractions of a second, thereby protecting the individual and equipment.

The versatile P211 allows users to easily replace blown fuses. Unscrew the forward portion of the body to access and replace the 6.3 x 32 mm type FF fast-acting ceramic fuse*.
Fuse rating: 0.5 A, 1000 V, 50 kA.
You'll be back to your project in no time flat.


Power Quality Blog has been created by Power Quality (Thailand) Co., Ltd. to share knowledge, and experience in solving power quality challenges. We focus on a wide range of power quality related issues, such as harmonics, transients, voltage variations, flicker, poor power factor, voltage sags and swells, and unbalance electrical loads etc.

PQSynergy™ International Conference and Exhibition

We organize an International conference annually. PQSynergy™ objectives is to support research and to share experiences in the related fields of power quality, energy efficiency, renewable energy, and smart grid. The conference is held normally in Thailand but occasionally is relocated around Asia.
