Read through this section carefully before connecting the EDL175 to the circuit being tested. 2.1 Location The distance between the EDL175 and the current lines must be at least half a meter (1.6 feet) for current lines carrying up to 600A, and at least one meter (3.3 feet) for currents between 600A and 2000A. 2.2 Connecting to the Electrical Network Connect the EDL175 to the AC power supply using the Power Supply Cord (No. 22 on Figure 1-3). Turn the slide switch (No. 8 on Figure 1-1) ON. 2.
2.5 CT Setup Set up the CT according to the PM175 Installation and Operation Manual, Table 4-1 or the PASUser’s Manual, Section 6.1.1. 2.5.1 Normal Measurement Set the CT = 1. 2.5.2 Direct Measurement (via clamps) All clamps require the CT according to the following formula: CT = I1ncl / I2ncl where: I1ncl and I2ncl are the clamp nominal primary and secondary currents.
IP = 3000, IS = 5, Ic=1000, CT = (3000/5) • (1000/1) • 0.005 = 3000. 2.6 PT Setup Set the PT according to the PM175 Installation and Operation Manual, Section 4.1 or the PAS User’s Manual, Section 6.1.1. 2.7 Voltage Probes Connection Connect the voltage probes to the EDL175 through the voltage connectors marked V1/V2/V3/VN. Connect the probes to the line conductors according to the power system configuration. 2.
2.8. 2 2.8. 3 Special Cables The manufacturer's special cables, together with the standard clamps, enable the EDL175 to perform measurements on high voltage lines via existing current transformers with 5A nominal secondary current by measuring the output of the current transformers. Standard FLEX Current Sensors The EDL175 can work with all standard FLEX and clamp current sensors which have a voltage output up to 3V RMS.
3.3 Battery Voltage Measurement The amount of remaining battery charge can be estimated by checking battery voltage (Vbat). This is done by connecting an external voltmeter with internal resistance of greater than 1M_ to the battery measurement sockets (see Figure 1-1, no. 10). If Vbat _ 12V, the battery is operating normally. If Vbat _ 11V, the battery is LOW. If Vbat_10.5V, the battery is fully discharged. Power supply: 100-240 VAC, 45-65 Hz, 30 VA. Battery: rechargeable; 12V/1.2Ah DC.
