In addition, 3-way isolation protects devices from transient surges and ground loops
on the data line.
In addition to the many built-in protection mechanisms, the device features an extended =36V common mode range to enable operation in electrically noisy environments and in the presence of ground loops
According to Drivdahl, the benefit of galvanic isolation is that it breaks ground loops
to help prevent unwanted current caused by different ground potentials from entering the device, therefore better protecting the AWK-1131A from voltage or other electrical surges up to 500v.
The MEP firms designed the entire system including the ground loops
and controls and avoided the temptation of defaulting loop and control design to contractors or vendors.
7 m) depth is the typical installation depth for residential horizontal ground loops
in the Fairbanks area.
Models are field-configurable and useful to eliminate ground loops
and interfacing sensors to PLC analog input modules.
Other features include a 360 [degrees] swivel mount that allows for easy cable orientation and minimises the restrictions of cable bend radius; hermetically sealed stainless steel sensor housing with optional PTFE jacketed cables to eliminate the restrictions of lower cost polyurethane cables in the presence of acid fumes; and case isolation to prevent ground loops
Mr and Mrs Pratt had plenty of ground space on their farm for installation of the ground loops
The isolation also breaks up ground loops
and reduces signal noise that could interfere with measurement accuracy.
A [+ or -]500-V galvanic isolation barrier prevents ground loops
Topics discussed include types of geothermal heat pumps, ground loops
, efficiency and load calculations, tax credits and rebates and calculating the net value or "payback" of the systems.
Additionally, Fairchild said that the FOD8012 supports communications of digital signals between systems without conducting ground loops
or hazardous voltages and also features a switching speed of up to 15Mbit/sec using its proprietary Optoplanar packaging technology and optimized IC design to achieve common mode rejection (CMR) of 20kV/[micro sign]s minimum providing noise immunity and extended temperature range of -40 to +110*C and a 3.
