1. Powertech UPSC Substation Capabilities

2. B-tech Developed Battery monitoring system which monitors Substation Batteries The prime objective of this system is to identify faulty batteries and have them removed. The system consists of an S5(brains and comms), BVM software Battery Validation Manager (analyzing software) and connections to each of the batteries in the line-up Major advantage of this system is the ability to extract impedance information from the cell Once this information is extracted it is sent to the BVM software for trending

3. B-tech Rising Impedance tells us that the cell is failing Trending the impedance can tell us when the cell will fail Cells with high impedance will not deliver the rated capacity Voltage can remain stable and mask defective cells All of this information is available via B-techs BVM software which can be communicated to via Ethernet, modem or serial connection. Modbus and DNP protocols are available. BVM software is easy to use, intuitive and Quickly identifies suspect batteries

5. research, develop and manufacture some of the highest quality, highest end switching equipment in the world, including high, medium and low voltage grounding switches, vertical breaks, center breaks, double side breaks, single side breaks, reversing switches, tilt types, telescopic types, semi-pantograph types, knee types and a complete range of manual and motor operators. EMSPEC machines all of their parts, no parts are casted. Casting cannot produce a consistant part with equal electrical and physical properties. Machining the switch parts produces a safe, easily maintainable, reliable switch. EMSPEC produces a modular motor operator which is safe reliable and easy to install and maintain. It allows easy interface to SCADA systems via multiple communication paths
