Core Drivers of Energy Use in Buildings

Perhaps one of the most important factors in the energy consumption equation is also one of the most overlooked: buildings. In many ways, buildings are essential to a sustainable future, particularly when you consider their architecture, design, construction, operation, and all the many activities that take place under their roofs. Growing energy awareness and reducing […]

Tracking how Electric Vehicles charging effect residential power usage.

This is a guest blog by Philippe Marseille. In it he explains his installation and setup of an eGauge system with Magnelab current sensors to monitor the power consumption of his Tesla S 85D (when charging), in addition to the overall consumption of his house. Hi, I like to track my energy usage (from my […]

Explanation of Accuracy Specifications for Current Transformers

Accuracy/Tolerance Explanations: A question is often asked about what the difference is between the tolerances specified by Magnelab and other companies. Don’t be deceived by the numbers or catch phases, know what you are getting when ordering current transformers (CT’s). When looking at the specifications for a CT, the accuracy rating or class can be […]

Current to Voltage vs Current to Current Transformers

Many meter manufacturers and others ask why use a Magnelab standard, pre-burdened voltage output current transformer (CT) for monitoring power instead of the traditional 5 amp output current transformer (CT) that’s been used for decades. There are several similarities and differences between the two CT types–the similarities are that both CT’s operate under the same […]

What does CT “burden” mean?

Why do you care about burden when ordering current transformers? Many of our customers regularly request quotes for standard and custom 5A ratio type current transformers but only ask for the window size and the input current with no knowledge of the “burden”. The burden is specified as VA or resistance (or impedance). We can […]
