The Hampden Model IL-100-3 is a three-phase variable inductance load bank. Each phase contains three individually switchable inductors, producing seven load steps.
Hundreds of electrical power transmission lines interconnect between a power station and its users. The flow of power, active and reactive, will vary on any or all of these lines by design and by circumstance. The variations are typically caused by changes in relative magnitude and phase angles of the sender and receiver voltages. The power flow in any particular line must be monitored and periodically altered to compensate for power changes occurring in interconnecting and parallel lines.
The Hampden Model TAI-100 Torque Angle Indicator consists of a circular plastic 360 degree protractor disc with .5 degree gradations, and a separate index line disc. The Bakelite collar of the protractor is fixed, but the protractor dial can be rotated. It is easily assembled to either end of a synchronous motor.
The Hampden Model H-PAM-100 provides a means of indicating the differences in frequency and phase between two AC sources.

The Hampden Model CL-100-3 is a three-phase variable capacitance load bank. Each phase contains three individually switchable capacitors, producing seven load steps.
The Hampden Model RL-100-3 is a three-phase variable resistance load bank. Each phase contains three individually switchable resistors, producing seven load steps. Individual phases may be used for DC or single-phase loading, or may be combined for three-phase AC loading.
Transmission lines are essentially for two purposes: 1. To transmit bulk supply of power to load centers. 2. For interconnection purposes; that is, for transfer of energy from one system to another in case of emergency or in response to diversity in system peaks.
The Hampden Model H-W/V-100 provides the student with the means for measuring both real and reactive power in a 3 phase circuit, as well as the direction in which the power is flowing.
