Composite Insulator Tester Elements

The Probe uses two infrared detectors to trigger the
E-field readings. Please refer to Figure 4. The two
infrared detectors are identified as IR1 and IR2.
The RS232 connector port is used to recharge the
Probe’s battery and to connect a Bluetooth dongle
for data transfer.
3.2 Tester Charger
The Probe’s battery is recharged using a 120Vac/220Vac universal wall charger connected to a
cable with a DB-9, RS232 female connector to connect to the Probe. A set of AC charger adaptors
is provided to accommodate various country standards. For charging the Probe in the field, a
12Vdc auxiliary automotive charger cable terminated in a DB-9 connector is supplied to recharge
the battery from a car or truck.
Both the AC power charger and the automotive DC charger are equipped with an LED status to
report on the charging status. When first plugged in to charge, the LED will glow red. After 9 hours
on charge, the LED will glow green, indicating that the charging time is completed.
The battery should be recharged overnight the day before a testing session. The battery charge
will last one day with the power switch in the ON position.
The battery can be recharged with the power switch in the ON or OFF position, however the Probe
will charge faster when switched off.
The data accumulated by the Probe must be transferred via Bluetooth to a Tablet/Laptop prior to
switching the Probe off or the data will be lost.
3.3 Insulator Tester Sled
The Probe mounts on a non-metallic sled. The sled permits the Insulator Tester to slide along an
insulator.
Together, the sled and Probe attach to a hot stick via the coupler mounted on the sled’s bracket.
See Figure 5.
