Energy Saving with Little Helpers?
I recently stumbled over some advertisements related to plug-in or paste devices which are claimed to reduce the electricity bill by an average of 10%.

The interactive graphics below shows the impact on sampling rates on different waveforms. The error calculation is based on true-rms for a wave with 360 samples and for training purpose only.
A user interface unit (UIU) is a remote access terminal for STS prepayment meters. The device is placed inside the users premisses while the energy meter is mounted outside and mostly not direct accessible.
Electronic energy meters can have various additional useful functions for tamper protection, event logging or billing.
As you maybe already know the New Year started not as expected. Cases of a contagious coronavirus have increased dramatically over the past weeks.
When we do high precision measurements we have to make sure that we are getting the measurement results as accurate as possible.
The measurement circuit of CLOU three-phase energy meters constantly monitors transition through zero on all phase voltages.
As usual our company has rented the Shenzhen sports stadium for the annual Spring Festival Gala and Outstanding Staff Award Ceremony.
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.
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)
