Over 30 years of Remote Terminal Unit engineering
Telvent's Remote Terminal Units (RTUs) designs are not tied to a "native" protocol enabling their units to be used not only with their SCADA control systems but with those of other suppliers as well. This results in fast and economical protocol implementation. Telvent offers four levels of RTU capability: Models 1310, 1330, 1350, 3030 from the very cost effective 1310 to the 3030 high caliber including custom designed retrofit packages of older RTU systems, substation automation platforms.

Seamless Integrated Communications for Power Automation Systems
Power utilities require to offer uninterrupted and reliable electric power to the public under harsh environmental conditions. Telvent ruggedized Ethernet Networks meets these requirements of EMI/RFT and extreme temperature variations. IEC 61850-3 and IEEE 1613 Standards for Ethernet Connectivity.
Ethernet switches, servers, modbus gateways, wireless products, media converters.
Transformer Temperature Controller TTC-1000
An affordable three probe transformer temperature controller that has built-in calculated winding temperature for one, two or three winding transformers, Tap position monitoring, LTC conditioning monitoring, DNP or MODBUS RTU communications on fiber and metallic, true three phase fan/pump motor monitoring, up to 14 digital digital inputs and data logging.
Time & Temperature Controller
Single or dual probe ambient temperature controller for automatically changing relay setting groups based on temperature, substation capacitor bank control and ventilation applications.
Positron engineers and manufactures high voltage isolation products to protect telecommunications circuits entering substations, power generating plants, cellular phone towers, and any high voltage area that is susceptible to the effects of Ground Potential Rise (GPR).
In the last 35 years, Positron has been the market leader in providing high quality, reliable wireline isolation equipment that meets the highest industry standards. Worldwide, there are more Positron isolator circuits deployed than any other vendor.
CD NOVA customers include all of the major power generation and transmission utilities in Canada.
