1. clothing Connect the system as above ensuring the Grounding cable is connected first and removed last The station or link box ground should be used for this purpose The signal ground wire can also be connected to this point but an independent ground may produce less ambiguous results Switch on the transmitter and set to 33kHz Also switch on the P2P transformer The reading on the meter should be just a few milliamps as the cable connected to will not be grounded However there should be sufficient signal current to trace Sometimes a small residual current reading will be shown on the meter this is normal NOTE Note that the high voltage LED will not illuminate even if connected to a live cable This is because it is associated with the other output ie the P2P output connections Trace the cable as in section Signal Clamp Method above 4 2 Fault Locating Having mapped out the route of the cable the process of fault locating can begin First confirm which is the faulty pair Check that the voltage between the shorted phases is less than 20V AC If the voltage is above 20V the fault is not a complete short in which case this method will probably not work The red LED on the P2P will also illuminate above 20V AC NOTE m Note that if the P2P output is connected to a voltage above 100V AC the internal fuses may blow Connect the P2P to the transmitter as below Ensure the Green ground lead is connected to the station link box2. 19 Woodside Road South Marston Industrial Estate Swindon SN3 4WA UK Central South America and the Caribbean Free Phone 0800 0281811 Ventas para Am rica Latina Tel 44 0 1793 822679 3251 Olcott Street Website www vivax metrotech com Santa Clara CA 95054 USA Email salesUK vxmt com Website www vivax metrotech com T Free 800 624 6210 Tel 1 408 734 1400 Fax 1 408 743 5597 Email VentasparaAmericaLatina vxmt com 3 Phase 2 Phase Phase 2 Phase P2P Isolating Transformer Vivax Metrotech Phase to Phase fault locating Guide using the vLocPro2 Kit and Phase 2 Phase P2P Isolating Transformer 3 1 Introduction This guide is intended to be used in conjunction with the vLocPro2 full user manual The vLocPro2 together with the Phase 2 Phase P2P isolating transformer is used for detecting the position of phase to phase short circuit faults on low voltage three phase buried cable Some brief reminder information regarding the vLocPro2 location kit is given below but this does not replace the full vLocPro2 user manual 3 2 vLocPro2 Receiver Main Display Z sp S5 wi e 3t INI Bd f nm ndn RAM yin Gain Control reduce gain 6 Frequency 15 db Gain Setting 8 Gain Control increase gain Information Depth Current Measurement 18 Location Mode Peak Null Sonde Broad Peak Arrows Note Bluetooth function is available in vLoc receivers with Bluetooth module only Pa
