SMARTPULSE™ MV INSTRUCTION MANUAL Section 2 – Installation This instruction booklet is intended as a general guidance tool for personnel installing Post Glover Resistors High Resistance Grounding Systems. However, each unit is designed for a specific application/installation. Please refer to the drawings supplied with your unit for ratings and other information. Appendix A contains dimension drawings with information for standard medium voltage systems.

SMARTPULSE™ MV INSTRUCTION MANUAL Refer to application specific drawings that accompany the Post Glover Resistors system. The free-standing enclosure is designed to accommodate the line cables through the sides of the enclosure without unnecessary cable bends. The control power connections made to the terminal blocks are rated for 20 amperes, 600 volts. The alarm output connections made to the terminal blocks are rated for 3 amperes at 120/230 VAC, 2 amperes at 24 VDC, and 100mA at 220 VDC.

SMARTPULSE™ MV INSTRUCTION MANUAL After the mechanical installation and all wiring is completed per specific equipment drawings furnished by Post Glover Resistors, Inc., place the system in service by following these steps: 3.3.1 Power the system by closing any external switches and/or energizing the transformer. Close SW1 and control power if it is separately derived.
Section 4 – Operational Description 4.1 HRG Functions The Post Glover Resistors SmartPulse Medium Voltage High Resistance Grounding System Equipment (HRG) coordinates the use of resistors and monitoring devices to create a high resistance ground for a power system. When a phase to ground fault occurs, the Neutral Grounding Resistor (NGR) limits the fault current.
The magnitude of zero-sequence charging current is determined by the line-to-ground capacitance associated with system components. The value of this current must be known to properly coordinate the Post Glover Resistors 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.
Normally, no maintenance is necessary for the SmartPulse high resistance grounding system. However, periodic inspections are needed to ensure that the controller is functioning correctly and the resistor is still capable of protecting the system. Post Glover Resistors recommends that the periodic inspections coincide with your normal system Preventative Maintenance schedule.
