AT series capacitive load device provides capacitive reactive power load for power system testing. Through independent switching of multiple capacitor banks, it simulates capacitive loads in actual grids. Main applications include:

Factory and type tests of power capacitor banks

Testing and commissioning of reactive power compensation devices (SVC / SVG / TSC / MSC)

Filter branch commissioning (combined with reactors)

Transformer capacitive load and temperature rise tests

Capacitor bank switching tests for MV switchgear

High-voltage cable charging current simulation tests

Generator under-excitation operation tests

Capacitive reactive power compensation tests for wind/PV grid integration

Multi-stage capacitor banks: Multiple independent capacitor units, each switchable individually for step-by-step reactive power adjustment

Multiple voltage levels: Covers LV 0.4kV to MV 35kV systems

Flexible switching modes: Manual, electric or automatic control

Complete protection: Over-voltage, over-current, over-temperature, fuse protection and discharge devices

Safe discharge: Each capacitor bank equipped with discharge resistors or reactors for fast discharge after power-off

Frame structure: Steel frame or container structure for easy transport, installation and expansion

Measurement and monitoring: Optional current, voltage, reactive power and temperature monitoring

Low-loss design: Low-loss polypropylene film capacitors with small heat generation and long life

Capacitor factory test: Choose small single-bank capacity with multiple banks to simulate various load conditions

Reactive compensation test: Match voltage and capacity with tested compensation device, configure reactors

Filter branch commissioning: Select reactor reactance rate based on target harmonic order (5%, 6%, 7%, 12%, 14%)

Switchgear switching test: Choose electric or automatic switching to simulate actual capacitor switching

Transformer capacitive load test: Match capacitive reactive power with tested transformer capacity

Outdoor installation: Choose oil-immersed capacitors or outdoor IP54 dry-type solution

Frequent switching applications: Choose thyristor switches (TSC) for fast response and no contact wear
