Page 3: Equipment Overview
Arc Flash/Blast Reduction: Eliminates hazardous energy during ground faults, which are present in 90% of all electrical faults. This instruction booklet is intended as a general guidance tool for personnel installing Post Glover High Resistance Grounding Systems. However, each unit is designed for a specific application/installation. The detailed drawings provided with each unit supersede the general information provided in this booklet. -
Page 4: Operational Description
Harmonic alarming. 2.2 Loss of Ground When the current mentioned above goes to zero, typically this indicates a Loss of Ground condition (i.e. grounding wire failure). If this occurs, the system will be Ungrounded. The PulserPlus Pro™ controller has an Under-Current / Under-Voltage feature that detects this condition for both Fundamental and 3 Harmonics. Upon detection, the green NORMAL indicating light will turn off and its auxiliary form-C contacts change state. -
Page 5: High 3 Rd Harmonics
Harmonics High 3 harmonics are also sensed by the PulserPlus Pro™ controller. An upper limit is set by the user for detection of current or voltage across the resistor. After a time delay expires; the amber THIRD HARMONIC indicator light will illuminate, the NORMAL indicator light will turn off, and an alarm horn will sound. Upon detection, the SYSTEM NORMAL and THIRD HARMONIC auxiliary form-C contacts change state. -

PulserPlus Pro™ module. The readings on the PulserPlus Pro™ module will be lower than normal readings due to the test resistor connected in series with the neutral grounding resistor. The purpose of the test resistor is to avoid a phase- ground-phase fault if an actual ground fault were to occur during testing. - Page 10 Press the RESET pushbutton and the red and green lights and auxiliary contacts should revert to their normal states. Without Test Resistor This test will verify operation of the PulserPlus Pro™ module only. The test bypasses the neutral grounding resistor and most of the circuitry by opening the neutral grounding circuit and applying control voltage (~120Vac) to the PulserPlus Pro™ controller module.

Page 11: System Capacitive-Charging Current
The magnitude of zero-sequence charging current is determined by the line-to-ground capacitance associated with system components. The value of the current must be known to properly coordinate the Post Glover High- Resistance Grounding System. In an industrial power system where the design and components are known, the charging current can be estimated with reasonable accuracy. - Page 12 PULSERPLUS PRO™ HIGH RESISTANCE GROUNDING SYSTEM PULSERPLUS PRO™ HIGH RESISTANCE GROUNDING SYSTEM INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS 4750 Olympic Blvd. • Erlanger, KY 41018 • USA Phone: 800-537-6144 / 859-283-0778 • Fax: 859-283-2978 www.postglover.com Serving the Electrical Industry Since 1892 ©...

Page 16: Hi Limit Setpoints
This feature multiplies the measured current by the selected CT ratio. For example, the physical limitation of the PulserPlus Pro™ module is 16A. If 20A is desired, a 30:5 CT is used to send a 0-5A signal the module. The CT ratio is set for 6x, so the measured current (0 to 5A) is multiplied by 6x. The display and alarming uses this... -
