Traceability of MV low power instrument transformer LPIT

2013 IEEE International Workshop on Applied Measurements for Power Systems (AMPS), 2013
In this paper the measuring and calibration techniques useful for ensuring the traceability of non-conventional instrument transformer, used in ac power plant up to 52 kV, are described and discussed. The aim of this work is to compare different calibration set up by evaluating the available uncertainty level.

Evaluation of Low-Power Instrument Transformers for Generator Differential Protection

IEEE Transactions on Power Delivery, 2018
In hydroelectric power plants, which are characterized by particularly high short-circuit current levels and high time constants, conventional current transformer (CT) specifications can result in increased equipment dimensions, thus complicating their installation, especially during refurbishment projects.

Optimized system operation with low-power instrument transformers

7th International Conference on Developments in Power Systems Protection (DPSP 2001), 2001
Switchgear operation is increasingly determined by electronic components. Powerful electronics allow the implementation of functions by means of software rather than hardware and hence the achievement of economic savings. This paper discusses the introduction of new low-power transformers.

Low-Power-Operated DC Instrument Transformers

IRE Transactions on Instrumentation, 1962
In view of the various applications of nonlinear-magnetic control devices in earth-satellite equipment with solar-battery supply, a low-power-operated prototype design of a miniaturized dc instrument transformer with single-turn or multiturn control has been recently developed.

Behavioral characteristic simulation research for a novel low voltage combined low power instrument transformer

Measurement Science and Technology
Abstract Low power instrument transformers (LPITs) have been massively penetrated in intelligent grids. This solution can be essentially extended to the case of low voltage networks, where the need for lower electrical insulation requirements allows the exploration of very compact and simple solutions.
