Transcription

1 PTTS series Power Transformer Test System components insure the customer years of reliable service from their transformer test system. 750kV Class Power Transformer Test Lab PTTS series power transformer test system is the complete test system for single and three phase power transformer and power reactor up to 765kV. The system will perform the following tests in accordance with ANSI / IEEE C and IEC 76 latest edition standards All test data are recorded automatically and the necessary correction calculations according to ANSI C57 and IEC standards are performed automatically. The system calculates corrected losses, efficiency, regulation and percent impedance. Computer aided data acquisition is increasingly becoming the standard as customers demand computer generated reports that reduce operator error. The system features Microsoft Windows based testing software which builds a data base of transformer test results and creates accurate final test reports in Microsoft Office format. Setup maps for each test are provided to reduce costly connection mistakes. Scope of Work: Samgor offer the turn-key project of the PTTS power transformer test system mainly consists of the station design, type selection and purchase of special equipment, equipment installation and commissioning, system connection, system commissioning, transformer test, training of the testing personnel, etc. The station is applicable to all delivery tests, type tests and some special tests of transformers. Samgor has developed transformer test systems that offer the customer reliability and flexibility solution. By utilizing Programmable Logic Controllers (PLC) in the control system, the PTTS series power transformer test system allows the customer the ability to add optional features or change the test sets operating procedures by reprogramming the PLC. This is much more cost effective than rewiring the test set as was required in traditional test systems. Reliability is a top priority for Samgor. Craftsmanship and the use of top quality materials and Design of the test station (including design of the primary and secondary systems, the equipment layout of the hall, the equipment wiring routing, embedded pipes, grounding system, etc.); Selection of the test equipment (including the research and development of special comprehensive intelligent measurement & control system and equipment procurement); Layout and installation of the test station (including installation of the primary & secondary loops, overall integration of equipment, construction of the grounding system and shielding system and so on); Supply of the measurement & control system of the test station and its installation and commissioning; Commissioning of the primary and secondary systems of equipment (including combined commissioning of all equipment);

2 Transformer test and training (completing the overall test of transformer according to testing standards and Project Pictures Overview: providing practical operation training for testing personnel ) Test Project: PTTS transformer test systems are designed to perform transformer tests in accordance with ANSI C57 and IEC standards, latest edition. These tests include: Winding Resistance Test Turns Ratio and Vender Group Insulation Resistance Measurement C & Tan Delta Measurement Excitation Current Measurement, Harmonics Analysis Excitation Loss (No-load or core loss) Test Impedance Voltage Measurement Full Load Current Measurement, Harmonics Analysis Copper Loss (Load loss) Test Temperature Rise Measurement, Heat Run Test Applied Voltage Test Induced Over Voltage Test Partial Discharge Test Impulse Voltage test / Chopping Wave Test Bushing Test Transformer Oil Test Sound Level Measurement Zero Sequence Impedance Measurement Radio Interference Test Transit Characteristic Test Etc. 50Hz/60Hz MG Set 200Hz MG Set VFD
