500ADM Primary Current Injection Test Set

Where higher currents and powers are required for primary injection, 6kVA (PCU1/E) and 20kVA (PCU2/E) primary injection systems are available. The PCU1/E and PCU2/E systems have separate control and loading units, allowing a wide range of load conditions to be covered with different loading units.

The 500ADM has two outputs, allowing injection of currents as low as a few hundred milliamps and up to 500A. Voltages up to 16V are available on the 40A output, allowing higher impedance trips to be tested. Four true RMS metering ranges are provided, allowing the full scale of the meter and trip level to be set independently of the selected output. Industry standard connectors are used on all inputs and outputs for convenience, reliability and safety. The unit is comprehensively protected by electronic overcurrent and thermal trips.

The timing system is very flexible without compro-mising ease of use, allowing trip times, reset times and reclose times to be quickly measured to a high degree of accuracy. Two contact inputs are provided, each of which may be trigged by a volt-free contact or a dc voltage. The contact inputs auto-sense for normally open or normally closed contacts.

The 500ADM can be used to test many devices including:

• Circuit breakers
• Primary injection of over-current relays
• Auto-reclosers
• MCB’s
• The unit can also be used for current transformer ratio testing and as a dual channel stand-alone timing system
