Negative Phase Current
Electronic energy meters can have various additional useful functions for tamper protection, event logging or billing.
Preventive Measures for Virus Control
As you maybe already know the New Year started not as expected. Cases of a contagious coronavirus have increased dramatically over the past weeks.
What is Measurement Uncertainty?
When we do high precision measurements we have to make sure that we are getting the measurement results as accurate as possible.
Wrong Phase Sequence
The measurement circuit of CLOU three-phase energy meters constantly monitors transition through zero on all phase voltages.
Welcome to the Year of the Rat 2020
As usual our company has rented the Shenzhen sports stadium for the annual Spring Festival Gala and Outstanding Staff Award Ceremony.
What are Transient Voltages?
Transient voltages are short time peaks in the a.c. power supply. They typically last a few milliseconds and the voltage can reach several thousand volt. A transient is by definition shorter than half cycle.
What is a Voltage Swell Event?
A voltage swell is a surge (increase) of voltage above 110 % of the rms magnitude in your power grid. The duration can be between ½ cycle and one minute. (EN 50160)
What is a Voltage Dip Event?
Sometimes it’s also referred to voltage sag (IEEE term). The meaning is the same. This article explains the power quality event logging inside of smart meters.
The First Breath Notification
The First Breath Push notification is sent to the head end system (HES) as soon as the meter is powered up.
The DLMS Push Message
A electronic energy meter with communication via DLMS can be configured to send Push messages.
Usually a meter acts as a server.
