‘Kusam-Meco’, pioneers of digital multimeters & clampmeters in India have introduced for first time a new intrinsically safe true RMS Digital Multimeter with PC interface model KM 822sEX. It has high transient protection of 12 KV (1.2/50mS) lightning surge.

New T6 Electrical Testers — the first tools with FieldSense technology — are now available. This enables simultaneous voltage and current measurements without metallic contact…

As the technology behind protection equipment has progressed, simple single-phase and transformer-based test devices are no longer up to the job. The transmission, transformer, motor or generator protection standards to be met in these systems tend to be numerical and three- or multi-phase in nature…

If the selection of inappropriate specifications switchgears go unnoticed, it may jeopardize safety of man and machines both. Therefore, utmost care is required, while designing an electrical protective scheme as far as selection of CTs of correct specifications, switchgears, etc is concerned.

As a result of the smart grid evolution, some recent enabling technologies have emerged to reduce the number of communication protocols and handle big amounts of data. The Internet of Things (IoT) is one of the most recent enabler for the smart grid.
