ACHIEVE IEEE 519-2014 COMPLIANCE WITH JANITZA AND MESSUNG

Posted by messungelectricalengineering on August 27th, 2021

In the world of power electronics, bad power quality can cause malfunctioning of sophisticated equipment. Newer-generation load equipment with microprocessor-based controls and power electronic devices, is more sensitive to power quality variations than was equipment used in the past.

The minor power disruptions which one would have noticed only as momentary flickering in the lights, may now interrupt the whole automated factory assembly line with sensitive electronic controllers or make all computers in a data centre or office go blank at once.

No wonder Power Quality (PQ) is the buzzword across industries and countries today. Both end users and utilities of electric power are concerned about the quality of power.

Some of the issues that adversely affect energy consumption, production and its quality include harmonics, voltage unbalance, voltage sag and flicker problems, standing waves and resonance. All these issues lead to huge loss in terms of energy, product, service, and damage to equipment.

PQ and reliability are critical for the successful delivery of a product and uninterrupted operation of an industry. It is even more critical for industry to pursue Energy Efficiency (EE) because of the increasing application of electronic loads and digital controllers which are sensitive to the quality of power supplied.

INDIA AND IEEE 519

In India,IEEE 519-2014compliance is slowly but surely becoming the norm for industries. It is becoming mandatory to implement energy management systems that meet IEEE 519-2014 standards. In India, Tamil Nadu has already made IEEE 519-2014compliance mandatory; Maharashtra will enforce it by 2023. No doubt other states will also follow suit.

 So it makes sense to build a futuristic EMS platform of devices, software and apps to meet IEEE 519-2014 &IEC 61000-4-30standards so you can reduce bills & penalties, optimise energy efficiency & uptime.

WHAT IS IEEE 519-2014

The Institute of Electrical and Electronics Engineers (IEEE), a non-profit professional association dedicated to advancing technological innovation related to electricity, has developed the IEEE-519. It is a system guideline for setting limits on voltage and current distortion, which is being followed by industries around the world.

The IEEE-519-2014 standard details the recommended practices and requirements regarding harmonic control in electrical power systems. It defines the specific and separate responsibilities for each participant – utilities and users – to maintain the voltage THD within acceptable limits at the Point of Common Coupling (PCC) between the utility and the user, and protect the user and utility equipment from the negative impact of harmonics.

HOW‘INDUSTRIAL’ CUSTOMERS CAN BUILD A HEALTHY PQ ENVIRONMENT

There are some basic precautions industrial customers can take:

• Undertake PQ monitoring and periodic power quality audit (PQ Audit)
• Maintain power factor within prescribed limits to reduce reactive power demand, which in turn will balance the voltage in their premise and also overall network
• Reduce harmonic currents while using more energy efficient equipment at their premise
• Keep a log of faced power disturbances at premises, which may come handy in finding effective solutions
• Capture financial information correlated with the PQ event for establishing return on investment in proposing any PQ mitigation proposal before the plant management.

HOWMESSUNG AND JANITZA CAN HELP

For efficient power quality monitoring, power measurement and analysing, Janitza electronics GmbH offers a globally renowned range of advanced devices and software. A world leader in development and manufacture of energy management solutions, Janitza\'s energy measurement technology, , GridVis® system software, energy data management systems, digital integrated measurement equipment, power factor controllers, harmonics filters and correction systems are setting the standard throughout the world.

Janitza’s UMG 512 PRO is a fixed Class A power quality analyzer in compliance with IEC 61000-4-30 Class A,EN 50160and IEEE 519-2014standards. It reliably records, analyses and documents all interferences such as harmonics, unbalance, transients, voltage dips, voltage swells, flickers, phase shifts and reactive power.

Janitza’s UMG 96-PA series of energy measurement devicesis the preferred choice for collecting and monitoring electrical measured values. Janitza technology enables energy management, and also power quality monitoring and residual current monitoring in a single device. Residual currents can be detected at an early stage and equipment damage avoided.

The UMG 96-PA-MID version also allows companies to record energy data relevant for billing.
