ENIP electrical measuring transducers

ENIP electrical measuring transducers are developed by the experts of the Engineering Centre «Energoservice» to provide prompt synchronized measurements of electrical networks parameters.

ENIP electrical measuring transducers have a function of measurements’ latch («freeze») in order to get simultaneous sections, i.e. to get measurements of electric grid parameters with common time marker. Fast response of transducers makes it possible to use them in monitoring systems of energy system transient behaviour (Wide Area Measuring Systems, WAMS).

Pilot models of electrical measuring transducers were developed in 2006. It is planned to start full-scale production of ENIP electrical measuring transducers in the second part of 2007.

Peculiar features of the electrical measuring transducers which are being developed are as follows:

Combination of fast response (40 or 10 ms) and high accuracy of measurements of electric grid parameters (accuracy class 0.5S, range of current measurement 1–120%);
Measurement of root-mean-square values of grid parameters, measurement of complex current amplitudes and fundamental harmonic voltage.

Developed electric measuring transducers are aimed at joint work with ENKS–2 and ENKS–3 data acquisition units and at autonomous work with the use of communication module and support of exchange protocol according to GOST R IEC 60870–5–104.

As an option ENIP transducers are equipped with communication module, and network wireless technology ZigBee and Wi-Fi are applied. Because of this it is possible to provide organization of additional communication link with the use of Wi-Fi (ZigBee)/Ethernet lock, and also to use wireless communication link to access the data or to configure transducers with the help of remote display module, PC or notebook.
