TRM Series Winding Resistance Meters are designed for field testing as well as for factory testing of large rotating machines & transformers up to 1000MVA, 765kV class under live switchyard conditions. DC Winding Resistance values of highly inductive objects like transformers, generators, motor etc. are directly displayed. A backlit LCD with a user-friendly menu sets up the instrument for the test. These meters are protected against the back-emf offered by large inductive windings.

SCOPE’s Single Phase (TTRM 101 / TTRM 102) and Three Phase (TTRM 301 / TTRM 302), Transformer Turns Ratio Meters are rugged yet light weight and highly reliable instruments to measure turns ratio of transformers in live switchyards up to 765kV.TTRM is equally suitable for use on manufacturing shop floor and test laboratories. It can be used for testing of single / three phase power transformers (star or delta connected, with or without neutral), CTs and PTs.

Cellular modem specifically designed for PME-PMI meters. Available for LTE Cat.4 / 3G / 2G, LTE Cat.1 / 2G, LTE Cat.M and Cat.NB / 2G networks.Our company develops cellular modems that work smoothly and are fully compatible with the 3-phase PME-PMI electricity meters. This device was designed to be fully compliant with all PME-PMI standards. Our cellular modems represent a future-proof migration solution to the LTE network with the same functionality, on higher data speed. Configuration and firmware updates can be done remotely, minimizing the need for costly site visits.This external modem can be mounted using a DIN-rail and connected to the meter through an RJ45 cable. It can be configured to “push” the data it reads from the meter to the HES periodically at pre-programmed intervals or triggered by an alarm/event (for example, power outage, cover removal, reverse run etc.).The modem reads actual and stored consumption data, recorded event log, load profile data, and can be used to read or modify certain parameters of the meter remotely. The device can be powered from the RJ45 connector.It can be accessed remotely through the cellular network and it can send data on the Internet by using an APN.The modem is fully configurable by our WM-E Term^®software.
