Figure 4 - Mains Connector with fuses
compartment
PTE includes two fuses located in the mains
connector on the front panel. Use fuses specified
for 250 V operation. To change the fuses, see
the Maintenance instructions in Chapter 7.6.3 on
page 113.
Figure 5 - Voltage and Current Output
Connectors
Output connectors only for generating voltage
and current up to 300V, 120A respectively. Not
intended to connect to circuits with higher
overvoltage categories (CAT II, CAT III and
CAT IV).
Communication connectors:
USB
- communication connector USB
RS-232
- communication connector RS-232
Connectors for voltage, current, frequency:
U1, U2, U3
- they serve for connecting voltage circuit of particular phase, Lo voltage
connectors of all phases are internally connected!
- PTE cannot generate testing overvoltage for electricity meters in CAT II,
CAT III, CAT IV and such voltages cannot be applied (by external devices)
during tests if electricity meter is connected to PTE
I1, I2, I3
- for connection of cables of current circuits for each phase independently; red
terminal is output, black ones are inputs. Bigger black output terminals work
up to 120A, smaller black output terminals work up to 12A
Fout
- BNC connector of impulse output (TTL) with LED indicator
Measuring connectors:
In A
- main signal input for current measurement
In B
- main signal input for voltage measurement
Aux
- universal (AUX) Input / Output connector
Accessories connectable into universal (AUX) Input / Output connector:
Optical Sensor
Impulse Input Base (for connection of Snap Switch or Impulse SO cable)
Frequency Output cable with BNC adapter
Accessories connectable into Signal Input A or Signal Input B:
Voltage Transducer VT 2x60 (max. voltage 500 V)
Voltage Transducer VT 3x30 (max. voltage 500 V)
Current Transducer CT 3x20 (max. current 20 A)
Current Clamps CC 2x12 (max. current 120 A)
Current Clamps CC 3x24 (max. current 240 A)
Flexible Current Probe FCP (max. current 6000 A)
