PGS simply stands for : “P” for Portable, “G” for Ground and “S” for Search system.

• The PGS can find faults that are on the positive rail, the negative rail, on both rails simultaneously, in a field device, or battery bank, regardless of whether they are high resistance, low resistance or in a capacitive environment.

• Designed with AE patented 21st century technology.

• The PGS has three (3) modes built into one analog machine:

• A mode where voltage on each rail, the fault resistance and the system capacitance are calculated and displayed.

• A mode that can find faults in a typical 135 Vdc low capacitive (≤ 2 µF) system that are from 0 Ω to >100 kΩ very quickly and accurately.

• A mode that can find faults in a typical 135 Vdc low to high capacitive (≤ 50 µF) system that are from 0 Ω to >100 kΩ quickly and with extreme precision.

• The PGS provides the operator with all pertinent information related to the system and fault conditions, as well as provides the operator with warning and PGS status messages.

• The PGS works on ungrounded systems (generally station battery systems) from 24 to 250 volts.

• The PGS is confined between rubber side grips and hangs by a magnetic strap at eye level from metal clad switchgear.

• The PGS assists in NERC PRC-002-6 compliance whereby the Station Battery and DC Power System must be inspected for inadvertent grounds every four months and aids to overall Nuclear Safety Risk reduction.
