TYPICAL PRODUCT APPLICATIONS
APPLICATION COMMON PROBLEMS PRODUCT PROTECTION CATEGORY (PG NO.)
GENERATORS- Insulation breakdown due to vibration and corrosion- Ground-fault currents often exceed short-circuit current- Arc-flash hazard from local and paralleled generators
Ground Fault (pg 43)Resistance Grounding (pg 61)Arc Flash (pg 73)
TRANSFORMERS - Overloading and overvoltage Resistance Grounding (pg 61)Feeder (pg 69)
SWITCHGEAR & MCCs
- Highest average downtime (IEEE 493-1997)- Arc-flash risk to personnel maintaining and working on live equipment- A fault on one load or feeder trips the entire lineup
Ground Fault (pg 43)Resistance Grounding (pg 61)Motor (pg 93)Feeder (pg 69)Arc Flash (pg 73)Pump Control (pg 129)
SWITCHBOARDS & PANELBOARDS - Low-level leakage current undetected by typical OCPDs Ground Fault (pg 43)
DRIVES- Switching frequencies cause nuisance tripping- Resistance grounded drives require sensitive, wide-frequency ground-fault protection
Ground Fault (pg 43)Motor (pg 93)Arc Flash (pg 73)
MOTORS & PUMPS
- Winding faults due to overloading, water, dust and vibration- Pump damage due to dry running, deadheading, rapid cycling, seal failure (submersible pumps), over heating, plugged intake, jammed impeller, or voltage fault conditions.
Ground Fault (pg 43)Motor (pg 93)Voltage Monitoring (pg 167)Pump Control (pg 129)
FEEDER CIRCUITS- Temperature and mechanical stress lead to severe damage- Older electromechanical protection is difficult to maintain- Uncoordinated feeders causing unnecessary downtime
Ground Fault (pg 43)Feeder (pg 69)
PORTABLE EQUIPMENT- Movement causing broken conductors and failed insulation- Requirement to keep low ground-fault potential- Loss of ground or high ground resistance due to cable faults
Ground Fault (pg 43)Feeder (pg 69)Arc Flash (pg 73)Ground-Conductor Monitoring (pg 57)Resistance Grounding/NGR Monitoring (pg 61)
GROUNDING RESISTORS - Open-circuit resistors due to corrosion or loose connections Resistance Grounding (pg 61)
WATER/WASTEWATER
- Electrocution hazard due to personnel working on submersible pumps or in vicinity of water and electricity- Pump damage due to dry running, deadheading, rapid cycling, seal failure (submersible pumps), over heating, plugged intake, jammed impeller, or voltage fault conditions.- Higher risk of arc flash and steam blast due to moisture- Electrical conductors can cause explosions in explosive methane atmosphere- H2S causing premature electronics failure
Ground Fault (pg 43)Motor (pg 93)Arc Flash (pg 73)Pump Control (pg 129)Time Delay (pg 262)Resistance Grounding (pg 61)
HVACR
- Voltage issues causing premature failure- Short cycling increasing wear and tear on compressors- Worn contactor causing voltage fault on compressor motor- Rapid cycling- Low voltage/brownout condition- Contactor chatter- Reverse phase in a 3-phase system- Overload
Motor (pg 93)Time Delay (pg 262)

GROUND-FAULT PROTECTION
Create safer working environments and reduce incidents of Arc Flash without affecting the uptime of critical operations. Vital in manufacturing and processing environments, sensitive ground-fault relays with advanced filtering will detect breakdown in insulation resistance without nuisance trips. Breakdown in insulation resistance can be caused by moisture, vibration, chemicals and dust.

Ground-Fault Protection Ungrounded AC Systems
EL3100 SERIESGround-Fault & Phase-Voltage Indicator
DescriptionThe EL3100 is a self-powered ground-fault and phase-voltage indication system for 3-phase systems. The EL3100 meets the National Electrical Code (NEC) and the Canadian Electrical Code (CEC) requirements for ground detectors for ungrounded alternating-current systems. Voltage connections are provided on the EL3100 for 208, 240, 480, and 600-V systems. Three green LEDs on the EL3100 indicate the presence of phase-to-ground voltage and one red LED indicates a ground fault. The EL3100 can operate stand-alone or with up to five remote LED indicators. A solid-state relay output provides indication of a ground fault. The output relay is closed when the 3-phase neutral voltage shifts as the result of ground leakage.

Ground-Fault Protection Ungrounded AC Systems
DescriptionThe PGR-3100 indicates the presence of voltage on each phase of a three-phase system. The LEDs on the panel illuminate when voltage is present. When a ground-fault occurs, the voltage on the faulted phase reduces to ground potential, causing the LEDs for the faulted phase to dim and the LEDs for the unfaulted phases to become brighter. Ungrounded ac systems are required by the National Electrical Code (NEC) Article 250.21(B) and the Canadian Electrical Code Part 1, Section 10-106 (2) to have ground detectors, such as the PGR-3100, installed on the system. External potential transformers (PTs) can be used to step down system voltage, allowing the PGR-3100 to be applied to any system voltage. PTs are not required for system voltages up to 600 Vac.

(Ground-Fault Indication System) (Insulation Monitor)
DescriptionThe PGR-3200 detects ground faults by continuously monitoring the insulation integrity of ungrounded electrical systems. The relay monitors the insulation for damage and assists with predictive maintenance and troubleshooting of developing ground faults by providing two warning and an alarm level. The PGR-3200 operates on one- or three-phase ungrounded systems up to 6 kV.
The PGR-3200 can also be used on a grounded system to monitor the insulation for damage, while the power system is de-energized. The mode-of-operation terminals (27-28) are connected to the circuit breaker or contactor auxiliary contacts to toggle the relay off when the contactor or breaker is closed.

DescriptionThe SE-601 is a microprocessor-based ground-fault relay for ungrounded dc systems. It provides sensitive ground-fault protection without the problems associated with nuisance tripping. Ground-fault current is sensed using an SE-GRM Series Ground-Reference Modulea resistor network that limits ground-fault current to 25 mA. The SE-601 is used on ungrounded dc systems ranging from industrial 24-Vdc control circuits to 1000-Vdc solar and transportation systems.
