1. Definition

A Load Bank is a controllable artificial load device. It replaces actual electrical loads to perform load testing, performance verification and calibration for generators, UPS, inverters and batteries. It converts electrical energy into heat (or consumes reactive power) to accurately simulate real-site load operating conditions.

2. Working Principle

Resistive Type (Most Common): Electric current passes through power resistors and converts energy into heat via Joule effect, cooled by forced air or water cooling; Power Factor = 1.0.
Inductive Type: Inductive coils consume reactive power to simulate motor and transformer loads with lagging power factor.
Capacitive Type: Capacitors provide capacitive reactive power for power compensation and filtering simulation with 超前 leading power factor.
Combined RLC Type: Integrated resistive, inductive and capacitive loads with adjustable power factor (0.1–1.0) to simulate complex working conditions.

3. Main Structure

Load components: Resistor / inductor / capacitor modules
Control system: Manual / PLC / remote control, step & continuous load adjustment
Measuring instruments: Voltage, current, frequency, power, power factor and temperature monitoring
Cooling system: Forced air cooling (portable type) / water cooling (high power & long-time operation)
Protection functions: Over-current, over-temperature, phase loss, short circuit and emergency stop

4. Classification

By load characteristic: Resistive, inductive, capacitive, combined RLC
By voltage level: Low voltage (400V/690V), medium & high voltage (3kV/6kV/10kV)
By installation: Portable / trailer-mounted, skid-mounted / fixed type
By function: AC type, DC type, harmonic simulation type, intelligent programmable type

5. Main Applications

EDG / MTG Generator Testing
Full-load & step load transient test; verify frequency and voltage transient response; long-term full-load endurance test for temperature rise, fuel consumption and protection setting calibration; paralleling and load sharing test.
UPS & Inverter Test
Power switching, backup duration, load capacity and harmonic suppression performance test.
Battery & Energy Storage Test
Capacity test, discharge curve measurement, internal resistance analysis and BMS protection verification.
Offshore & Explosion-proof Application
Explosion-proof load bank with Ex'e, Zone 2, IIA T3, IP65 for outdoor skid-mounted EDG/MTG regular load maintenance, avoiding carbon deposition and wet cylinder caused by no-load or light-load operation.
New Energy Industry
Energy dissipation for wind & PV inverter, grid adaptability test.

6. Key Technical Parameters

Rated power (kW/kVA); rated voltage & frequency; adjustable power factor; step/continuous load regulation; measurement accuracy; air/water cooling; explosion-proof & ingress protection grade (Ex certification, IP65).

7.Summary

A Load Bank is a professional simulated load facility for power equipment. It can accurately test the load capacity, voltage/frequency stability, protection logic and paralleling performance of generators and power supplies without connecting real on-site loads, widely used in power generation, offshore engineering and data center industries.
