Generator Neutral Grounding & Leads Cubicles

Generator grounding and measurement cubicles combining neutral-grounding resistance, current measurement and generator-line interface functions.

GENERATOR NEUTRAL / GROUNDING CUBICLES

GENERATOR
NEUTRAL → GROUNDING
RESISTANCE → MEASUREMENT
INTERFACE

Conceptual functional grouping; actual cubicle design is project-specific.

TECHNICAL OVERVIEW

Purpose and operating principle.

LMZ generator neutral cabinets create and monitor the generator neutral/star point through resistance grounding, while generator incoming switchgear provides line-current and voltage data together with protection functions.

RATED VOLTAGE

Up to 13.8 kV

RATED CURRENT

Up to 3000 A

ANTI-CONDENSATION

100 W heater

PROTECTION

MV fuse / surge options

KEY FEATURES

Project-relevant characteristics and selection points.

Test terminals for current- and voltage-transformer secondaries.

Circuit diagram included in the terminal box.

100 W anti-condensation heater.

Zinc-oxide lightning arresters and surge capacitors available on demand.

Voltage-transformer fuses with signal contacts.

Medium-voltage fuse protection.

RESISTOR SYSTEMS

Electrical and thermal duty define the final resistor configuration.

LMZ resistor systems are selected around the network, current, voltage, thermal duty, operating cycle and environmental requirements of the application.
