Trench ccvt manual

CCVT's consist of a capacitive voltage divider along with a step down transformer and other associated equipment. Placing capacitance in series and shunt to the natural inductance of the power system leads to resonant circuits and RC time constants that affect the faithful reproduction of the primary voltage on the We have a strong, experienced Team at Trench who are all committed to providing the best customer care.

All Trench Instrument Transformer Products contain oil, which has less than 2-PPM PCB considered as non-detectable amount. Storage & Transportation Carrier Terminals for a Trench TEIRF 115kV CCVT and an Alstom Type OTCF-300 CCVT, respectively. Figure 4: Trench and Alstom CCVT Baseboxes (showing Carrier/HF Terminal) 2.3 The Potential Terminal The test procedure for performing a Power Factor measurement on a CCVT is largely dictated by if the CCVT has an accessible Potential Terminal. The circuit diagrams, drawings and other data in this manual may vary in minor details, from the equipment supplied. In all cases the diagrams supplied by the factory and identified with the equipment will be correct in all details. The contents of this manual are designed to cover most situations, which may occur in practice. Line Traps are designed to meet ANSI standard C93.3, IEC stan- dard 60353 or other international The major components of a Line Trap are the main coil, tuning device and protective device Since Line Traps are series connec- ted with the HV transmission line, they must be designed to with- stand the high mechanical forces generated by the short GE Digital Energy g IEC/IEEE Capacitive & Coupling Capacitor Voltage Transformers (CVT & CCVT) 72.5kV - 1100kV (350kV - 2500kV BIL) with Primary Plus TM Pre-engineered solution set that digitizes XD|GE primary equipment and provides factory installed and configured protection, monitoring, diagnostics and communications. in order to validate the CCVT model in time-domain studies. IEC 186 Standard [8] establishes that for the ferroresonance test the CCVT must be energized at 1.2 per unit of rated voltage. One of the CCVT secondary terminals with a nearly zero burden is then short-circuited. The short-circuit must be sustained during three cycles, at least. Trench Limited has developed a "special" CCVT design and / or "field installation kit" to solve this problem. II. CCVT BASIC PRINCIPLE AND DESIGN Coupling Capacitor Voltage Transformers (CCVT's) are designed to be applied on high voltage transmission systems to provide lower more manageable (approximately 57-115V) The authors are with Trench CCVT and CC Instruction Manual & Testing Procedure - Free download as PDF File (.pdf), Text File (.txt) or read online for free.
