Synchroscope. 110/100V. The M8100 Synchroscope provides illuminated indication of the frequency and phase deviation between voltages on two separate AC systems (e.g. a generator and a busbar). The M8100 will also indicate whether or not the two systems are live. A moving light dot indicates the frequency deviation. The magnitude of the frequency deviation is indicated by the speed and direction of the movement. Clockwise movement indicates that the frequency is too high on the incoming system. Counter clockwise movement indicates that the frequency is too low. A steady light dot at 6 o’clock position indicates zero frequency deviation and 180 degrees phase deviation. Exact synchronization. frequency and phase accordance is achieved when the light dot is steady at the 12 o’clock position (when the green LEDs ignite). The M8100 scale is made up from 38 bright red LEDs. The resolution provided by the 38 LEDs is almost as fine as a pointer synchroscope, however the LED based design is far better at withstanding environmental influence from vibration, temperature and humidity.

Indicator Panel, 20 channels. The Alarm Indicator, M4700 provide flush mounted LED based indication with 20 channels. Each channel can be used to indicate the state of one potential free contact. All indicator units are available with either negative or positive reference. An insert paper label provides the opportunity to print a description or instruction right next to the related channel LED. The indicator units are available for both DC of AC supply. Input signals can be +24 VDC, +48 VDC or +110 VDC. The indicator panel is also equipped with an alarm relay, a siren relay and a built-in siren. A TEST push button located on the front will, while activated, ignite all LEDs to confirm proper operation. An auxiliary push button is provided for application dependant use. The auxiliary push button is directly connected to the plug-in terminals on the rear side of the unit.

Reverse Power Relay. 400/450V L-L 1A. Protects the generator from being run as a motor. The Reverse Power Relay T2000 will protect the generator from being run as an electric motor. The T2000 will protect the prime mover of the generator against physical damage, but will also protect the parallel running generators from overload caused by the inversed load shift in a reverse power situation. T2000 reverse power relay function: The T2000 measures the current through an external 5A CT attached on phase L1. The phase angle (phi) is determined from the voltage measurement across L1 and L2. The T2000 calculates the active current as I x cos phi. If the active current becomes negative and exceeds the preset level (2 – 20 percent), the pick-up LED will activate and the trip delay timer (2 – 20 seconds) will also activate. The built-in trip relay will energize after the delay has passed, provided that the preset trip level was continuously exceeded during the time of the delay.

Indicator Panel. 20 channels, 24V DC.. The Alarm Indicator, M4700 provide flush mounted LED based indication with 20 channels. Each channel can be used to indicate the state of one potential free contact. All indicator units are available with either negative or positive reference. An insert paper label provides the opportunity to print a description or instruction right next to the related channel LED. The indicator units are available for both DC of AC supply.

Short Circuit Relay. 24V DC 5A. The T2300 is intended for protection of generators, power transmissions and consumers against damage caused through short circuit by tripping the circuit breaker. The relay detects the highest of the 3 input currents and on exceeding the preset values, an output relay will be activated after a preset time delay or momentarily (0.1 second).

Dual Overcurrent Relay. 400/450V 1A. The T2400 consists of two combined over current relays, intended for protection, or monitoring of generators, power transmissions and consumer supply. A typical application for protection of a generator is for one of the over current functions to trip the generator breaker and the other over current function to trip a nonessential service. Both over current functions could be used to trip 2 levels of nonessential load. The relay detects the highest of the 3 input currents and, on exceeding the preset values, output relays will be activated after preset time delays.
