The BGFL Class 1 Ground Fault Relay Manufactured by Electromagnetic Industries LLP meets NEC service entrance equipment standards. The BGFL Operates with molded case power circuit breakers,  bolted pressure switches, or fusible disconnect switches.

The BGFL, has an Electro-mechanical relay output positive “ON” and “OFF”. The BGFL has two styles, “Standard” (without interlock) and “Zone Interlocking”, Integral test panel with “Push to Test” and “Shunt Trip Bypass” pushbuttons for proper testing of device with the ability to trip or not trip the protective device. It also has a visual trip indicator, adjustable time delay, discrete current threshold adjustment.

 

 

The BGFL Ground Fault Relay Manufactured by Electromagnetic Industries LLP along with the accompanied sensor are used together to provide a system for detecting ground fault current in a grounded AC power System. When the system detects a fault, of a preselected level for the duration of a preselected time delay, the relay initiates a trip of the Shunt Trip Device to open the contacts/breaker and clear the Ground Fault.

 

The Electromagnetic Industries BGFL Ground Fault Relay has current trip set points of 5 – 60Amps, 30 – 370 Amps and 100 to 1200 Amps. The BGFL is UL Listed.

The GFP Ground Fault Relay Manufactured by Electromagnetic Industries LLP is a Class 1 relay that  meets NEC service entrance equipment standards. The GFP Operates with molded case power circuit breakers,  bolted pressure switches, or fusible disconnect switches.

The GFP, has an Electro-mechanical relay output positive “ON” and “OFF” and  has two styles, “Standard” (without interlock) and “Zone Interlocking”, Integral test panel with “Push to Test” and “Shunt Trip Bypass” pushbuttons for proper testing of device with the ability to trip or not trip the protective device. It also has a visual trip indicator, real time Ground Fault level display, adjustable time delay, discrete current threshold adjustment. The GFP also retains the information of what the Ground Fault level was at trip/power down.

 

The GFP Ground Fault Relay Manufactured by Electromagnetic Industries LLP along with the accompanied sensors are used to provide a system for detecting ground fault current in a grounded AC power System. When the system detects a fault it will display the level and at a preselected level for the duration of a preselected time delay, the relay initiates a trip of the Shunt Trip Device to open the contacts/breaker and clear the Ground Fault.

 

The Electromagnetic Industries BGFL Ground Fault Relay has current trip set points of 5 – 60Amps, 30 – 370 Amps and 100 to 1200 Amps. The BGFL is UL Listed.

The GFM manufactured be Electromagnetic Industries is a (Class 1) Ground Fault protection system used to minimize damage to equipment due to arcing ground faults. The GFM system is designed for all poly-phase applications and is ideal for motor control, motor control centers and high voltage starters

 

The GFM relay comes in 3 Model/Series. GFM 200, GFM 300 and GFM 400.

The CTD-1 manufactured by Electromagnetic Industries is designed to provide a source of energy for a circuit breaker or switch to trip during a loss of normal AC or DC power.

These devices are protected against inadvertent short circuits, input from line surges and inductive kickback from trip coils. The nominal 120Volts AC or 125 DC is applied between “AC” and ‘COM” terminals. This voltage is half wave rectified and applied across the trip capacitor to give the output trip voltage. The charge stored in the capacitor (330 uF @168 VDC) is available between “ ” and “COM” terminals for the trip coil operation. The half wave rectification

circuitry provides the advantage of maintaining a common neutral connection from the input and output while still maintaining the charge in the trip capacitor after a loss of control power.

The capacitor is continuously charged when control power is applied. This provides energy for normal trip coil operation. Because mechanical relays are not used, energy from the trip coil operation is immediately available with the loss of control power. When the control power returns, the capacitor  will recharge and will be able to supply energy for the next trip coil operation.

 

The CTD-2 manufactured by Electromagnetic Industries is designed to provide a source of energy for a circuit breaker or switch to trip during a loss of normal AC or DC power.

These devices are protected against inadvertent short circuits, input from line surges and inductive kickback from trip coils. The nominal 120Volts AC or 125 DC is applied between “AC” and ‘COM” terminals. This voltage is half wave rectified and applied across the trip capacitor to give the output trip voltage. The charge stored in the capacitor (1500 uF @ 168 VDC) is available between “ ” and “COM” terminals for the trip coil operation. The half wave rectification

circuitry provides the advantage of maintaining a common neutral connection from the input and output while still maintaining the charge in the trip capacitor after a loss of control power.

The capacitor is continuously charged when control power is applied. This provides energy for normal trip coil operation. Because mechanical relays are not used, energy from the trip coil operation is immediately available with the loss of control power. When the control power returns, the capacitor  will recharge and will be able to supply energy for the next trip coil operation.

The SPVR (Three Phase Voltage Monitor) manufactured by Electromagnetic Industries is designed to protect electrical equipment from Phase Loss, Phase Unbalance, Phase Reversal, Under voltage and Overvoltage conditions.

 

A correctly installed SPVR (Three Phase Voltage Monitor) Voltage Sensing Relay will protect from Phase Loss, Phase Unbalance, Phase Reversal, Under voltage and Overvoltage conditions. The SPVR has an adjustable time delay for the trip as well as for the reset. It also has an adjustment for the Phase Unbalance (from 2% to 8%). The Phase Reversal is an instantaneous trip regardless of what the time delay is set for. The SPVR will hold in memory the condition that tripped the unit even after a power loss. The trip can be identified by pressing the “FAULT INDICATION” pushbutton up to 7 days after the fault. The SPVR will automatically reset at power up.

 

OCP

 

1-OCP, 1-OCP-100, 1-OCP-200, 1-OCP-400, 3-OCP, 3-OCP-100, 3-OCP-200, 3-OCP-400

 

A Current Transformer secondary should never be open circuited while the Current Transformer primary circuit is energized. If this situation should occur there is a possibility of developing extremely high voltages which could be dangerous to personnel or cause an insulation breakdown.

The 1-OCP series of Open Circuit Protectors manufactured by Electromagnetic Industries LLP. are voltage sensing devices using high speed shorting SCR switches. When the secondary peak voltage exceeds the clamping voltage value, the SCR operates, shorting the C.T. secondary

and reducing the voltage to about 2 volts in less than 1/4 cycle. This process repeats each current polarity reversal. The protection is activated each half cycle.

 The single  element Open Circuit Protector is provided with two terminals for connection across the secondary of  the C.T’s and in parallel with the burden. It can also be connected across the current terminals of a protective relay, meter or other current operated device without affecting the operation of the device. Secondary polarity of the C.T.’s is not critical to the OCP.

The OCP also provides protection against high secondary voltage transients, which may damage the burden or secondary winding. If the transient voltage exceeds the voltage clamping limit, the Open Circuit Protector will trigger. After triggering, the voltage will fall to about 2 volts and remain there until the next zero crossing of the current waveform at which time the device resets and the cycle repeats as necessary. In the transient mode of protection, triggering will

occur only on the half cycle where the transient appears. The leakage current of the OCP is insignificant and will not cause a ratio or phase angle error in the Current Transformer accuracy.

Metering class C.T.’s with a rating factor of 2 could operate up to 10 amps on a continuous basis. The OCP is designed to tolerate both this  condition and (80 amp RMS) for 2 seconds. 1-OCP
