Maxwell Technologies Introduces Electronic Voltage Transformer for More Accurate Grid Measurement
Press release date: August 26, 2014
EVT Provides Integrators, Utilities with Smaller Footprint, Lower-Weight Solution for Compact Substations
SAN DIEGO, – Maxwell Technologies, Inc. (NASDAQ: MXWL), a leading developer and manufacturer of ultracapacitor and high-voltage equipment, announced its new Electronic Voltage Transformer (EVT) for smart grid applications that range from 110 kV to 550 kV. The EVT is the latest addition to Maxwell's CONDIS® family of high-voltage capacitors and capacitive dividers, and is used for digital current and voltage monitoring in smart grids to guarantee measurement accuracy of the grid. The EVT can replace the traditional capacitive voltage transformer (CVT), and is about one-third the size and weight.
GTM Research forecasts the cumulative value of the smart grid market to surpass $400 billion by 2020. As the smart grid market grows, there are more automated substations that require accurate current and voltage monitoring. The Maxwell EVT's low voltage output and high temperature stability are key factors in improving measurement accuracy, while its lighter and slimmer size, as compared to the CVT, allows integrators and utilities to save a considerable footprint in each substation that is operated.
This next-generation high voltage capacitor divider was developed in conjunction with select Maxwell customers. It is characterized by a low voltage output at 100V, with a simple connection that permits direct digital treatment of the signal, high stability over a broad temperature range and optimal performances with an increased frequency bandwidth.
"Substation owners have relied on large CVTs for the past 60 years, and they can now look forward to a modernized, compact solution that more accurately monitors and measures digital current and voltage," said Sacha Jenny, general manager, Maxwell SA and vice president of high tension. "The EVT helps meet the needs of the growing number of automated substations to ultimately improve grid efficiency, and will also help Maxwell increase its customer traction in the electric utility market."
With this new product, Maxwell Technologies expands its portfolio of capacitive and resistive-capacitive dividers for monitoring and measurement of medium voltages (10 kV to 50KV) and high voltages (50 kV to 1200KV).
