Basler Electric BE1-59N Ground Fault Overvoltage Relay

Overview

The BE1-59N provides accurate 100% stator-ground protection for ungrounded

and high-resistance grounded generators.

Features

• Provides 100% stator ground fault protection.

• 100/120 Vac or 200/240 Vac nominal sensing input.

• Four sensitivity ranges for overvoltage: 1 to 20 and 10 to 50 Vac for a

100/120 Vac input and 2 to 40 and 20 to 100 Vac for a 200/240 Vac

input.

• Four sensitivity ranges for undervoltage: 0.1 to 2.5 Vac and 0.5 to 12

Vac for a 100/120 Vac input and 0.2 to 5 Vac and 1 to 24 Vac for a

200/240 Vac input.

• Instantaneous, definite, and inverse time characteristics.

• 40 dB harmonic filtering.

• Low sensing input burden.

• Power supply status contact.

Benefits

• Limit generator damage with 100% stator ground-fault protection.

• Wide range of applications covered with four overvoltage and four

undervoltage setting ranges.

• Meet protection timing requirements with instantaneous-, definite-, and

inverse-time characteristics options.

• Accurate detection of fundamental and third harmonic content using 40

dB harmonic filtering.

• Minimized potential transformer (PT) costs as a result of low sensing

burden.

• Reduced battery load with low burden power supply.

• Accurate, repeatable, and reliable operation.

• Simple human-machine interface (HMI) provides clear and intuitive

settings for easy configuration.

• LED targets provide clear annunciation of status.

• Easily perform in-case system and device tests using test plugs.
