Page 2: Important Safety Notice
Important Safety Notice Aspects of the installation and commissioning of the PQSensor™ involve working on equip- ment where errors in installation or failure to follow appropriate safety procedures could result in exposure of personnel to Lethal High Voltages. Installation of the PQSensor™ should only be performed by personnel with the necessary knowledge and training. - Page 3 1 GENERAL The purpose of a PQSensor™ is to equip a standard CVT with an interface that enables it to be used to make accurate measurements of harmonic levels and transients on h.v. power net- works. CVT Electromagnetic Unit Tank CVT Secondary Terminal Box PQSensor™...
- Page 4 Measurement Unit is also equipped with a test circuit that can be used for on-site testing and calibration. Detailed dimensions of the Measurement Unit are given in Appendix I. It is equipped with three M3 mounting holes on the base. These holes are compatible with the Phoenix UTA98 DIN rail adapter (provided) and can also be used together with other custom made mounting plates.
- Page 5 (see Figure 2). The polarity of these inputs must be respected by connecting the HCCT2 and LCCT2 inputs to ground as shown. Use a schematic of the target CVT to identify the connec- tion points for these MU inputs. In all cases a marked up CVT schematic must be used for the design, installation and checking of the MU installation.
- Page 6 3 FACTORY INSTALLATION AND CALIBRATION OF THE PQSENSOR™ Only the Measurement Unit is permanently installed in the CVT in the factory - the Intercon- necting Cable and the SCM should be installed as part of the site installation and commission- ing procedure.
- Page 7 N.B. A mounting plate or bracket will be required to secure the SCM to the CVT structure. Since there is a wide variety of support structures used in substations this bracket is NOT provided with the PQSensor™ and will normally be sourced locally. 16.
- Page 8 4.5 PQSensor™ Installation wiring check When the CVT is energised it is not possible to gain access to the CVT secondary terminal box so the wiring must be checked and tested before energisation. To facilitate testing apply a suit- able supply voltage to the SCM. Next, using a secondary injection test set inject the Reference Test Current as given in the PQSensor™...
