Applications:
The Grounding Transformer is a
kind of auxiliary transformer that used to offer an earth point for the
Delta-Star system. They are typically used for providing a path to ground for
unbalanced load current and for fault currents on system where a suitable
ground is otherwise not available.
Design:
The grounding
transformers are generally designed with one of the two configurations: Zig-Zag (Zn) with or without
an auxiliary winding or a Wye (Ynd) with a delta connected secondary. The
Zig-Zag connection is preferred as it is more cost effective and have smaller
size than the Delta-Wye unit. For more safety, neutral earthing resistors (NER)
are often used in conjunction with the grounding transformer to limit neutral
ground fault current magnitude. The rated voltage of the NER should be equal to
the line to ground voltage of the grounding transformer. The current rating and
duration should match the grounding transformer

Iqiyi TV Q1 is OK?
As a video platform, providing users with a better video playback experience is naturally one of their pursuits. This is one of the reasons why iQiyi has launched this TV Fruit Q1. By wirelessly projecting the contents of the mobile video app, we can instantly output larger-sized images on the TV.

But on the other hand, "casting artifact" in a search on a treasure a lot, cheaper than the 198 yuan TV Q1 also abound, then TV Q1 really have sufficient competitiveness?
Appearance, material hanging like products
As a single-function projection artifact, many manufacturers are trying to reduce the cost of the compression shell and material to bring a lower price. In contrast, TV Fruit Q1 is very hard: the front panel of the fuselage is made of glass, and the rose gold frame is processed by CNC trimming, which is more in line with the aesthetic needs of the current users.

There is a small opening in front of the fuselage to provide the user with LED light indications at power on.

iQiyi TV Q1 is made of polycarbonate at the bottom of the fuselage and a circular hole for reset is located on it. The only small regret is that the bottom of the fuselage does not increase the rubber foot pad, the product is easy to run around in a smooth plane.
The bottom of the fuselage design
Iqiyi TV Q1 machine measurements only 45 × 45 × 16mm, basically only the size of a palm, will not occupy too much desktop space. The fuselage does not have any buttons, only the HDMI interface and the USB power supply interface are set behind the fuselage, very simple.

Connection and setting are simple Unfortunately, 5GHz network is not supported
Since there is no button, iQIYI TV Q1 does not need to perform some complicated switching operations. After connecting HDMI and USB, the product is plug and play, that is, it is switched off. If you are connected to a smart TV, then you can completely connect the USB to the back panel of the TV. You don't need to occupy the socket hole in your home. This is also very close.
Just connect HDMI and USB wiring
After connecting and loading, the screen gives a two-dimensional code for the user to scan and download the TV Fruit App. The user uses the TV App to enter the password of the existing home Wi-Fi network, and after several seconds of automatic settings, the iQiyi TV Q1 is successfully connected to the router.

Connection process
Here we need to explain that if the mobile phone is connected to the 5GHz band network in advance, the TV Android App will indicate that the product does not support the 5G band and requires the user to change to the 2.4G band Wi-Fi network. For this part of the user, switching the network operation will slightly increase the operating cost. Although the 2.4GHz band is also sufficient to support the smooth transmission of 1080p video, but from the perspective of user operating costs, we hope that the next generation of TV can support 5Ghz band Wi-Fi network.
After the connection is successful, we can use the DLAN or AirDrop function of various applications to perform screencast operations on the TV. After this, TV Fruit App can reserve the virtual remote control button for us in the mobile phone notification bar to facilitate remote control when we need it. This is also a very creative design.

Casting smooth and stable
Finally, let's take a look at the actual screencast effect:

We are testing on the iOS platform. You can see that when you use the various video applications, the picture is very smooth, and the packet loss rate is low and the picture quality is delicate. Even if the app exits, iQiyi TV will continue to play the current program without worrying about the interruption problem when the mobile phone cuts off to chat with WeChat.
When using the AirDrop channel, some applications have compatibility issues, which are expected to improve with the firmware update.
to sum up
iQiyi TV Fruit Q1 is a very simple and easy to use, smooth and stable cast screen artifact, compared with similar products, the obvious advantages, the intention of the appearance of work and intimate interface design will bring a higher attachment for this product value. From these perspectives, iQiyi TV Q1 is a very good and worthy product.

But on the other hand, we noticed that the price of 198 yuan for iQiyi TV Q1 is not dominant compared to other products, and it is even close to some TV boxes that have the screen-casting function. Therefore, users do not have a good reason to pass high investment. To buy this single screen-casting Iqiyi TV Fruit Q1. Therefore, we believe there will be some adjustments in the positioning of this product.
