Basler Electric BE1-87TE1EA1JD1N5F Transformer Differential Relay

The DGC-2020HD provides analog outputs to the power system in the

form of analog bias signals to the voltage regulator and speed governor.

A pulse width modulated (PWM) speed bias output is also available.

When the generator breaker is closed and load sharing is enabled, the

DGC-2020HD shares the real power load proportionally with other

generators in the system. Load sharing can be implemented on the Analog

Load Share Line or through Ethernet communications. Reactive power

(kvar) sharing is accomplished through Ethernet communications.

The DECS-200N is a very compact Negative Forcing Digital Excitation

Control System.

Engine Protection and Metering

Engine protection features include oil pressure and coolant temperature

monitoring, overcrank protection, ECU-specific protection elements,

and diagnostic reporting.

Metered engine parameters include oil pressure, coolant temperature,

battery voltage, speed, fuel level, engine load, coolant level (from ECU),

ECU-specific parameters, and run-time statistics.

Generator and Bus Protection and Metering

Multifunction protection guards against overvoltage, undervoltage,

excessive forward and reverse power, underfrequency, and

overfrequency. Overcurrent, phase imbalance, loss of mains,

frequency rate-ofchange, phase differential, and neutral differential

protection are available as options. Each protection function has

an adjustable pickup and time delay setting.

Sixteen inverse time curves, in addition to user programmable

curves, enable the DGC-2020HD to offer overcurrent protection in

a variety of applications. Each protective element can be assigned

to protect the generator, bus 1. or bus 2 sensing inputs with settings

groups.

Metered generator and bus parameters include voltage, current,

frequency, vector shift, real power (watts), apparent power (VA),

and power factor (PF).
