Overview

This meter relay can measure the earth resistance value of a contactless AC circuit while also detecting abnormal earth resistance values in the same circuit. Comprising a contactless meter relay and an extra power unit, this meter relay can be used for a wide range of purposes such as detecting abnormalities in grounding accidents in settings such as boats.

A particularly useful feature is the fixed voltage circuit built into the extra power unit, which maintains a roughly fixed voltage circuit even during fluctuations of ±10% in the input voltage of AC115V, preventing measurement error.

Features

● Earth resistance measurements can be taken continuously while also setting and detecting the desired earth resistance values on the scale of the photoelectric-type detection setting mechanism, as well as activating warning equipment using the relay circuit contact.
● Lines can be measured and detected while live.

Specification

Note 1) Meter Action: Passage Type – The pointer can pass to the end
of the scale even if it exceeds the
setting value.
Note 2) Output: Retaining Type – Output is retained even when the pointer passes the setting value.
The output is discarded when the pointer goes back below the setting value.
Note 3) Others:
a) DC circuit type can also be manufactured
b) See the page about our contactless meter relay for details.
c) In particular, a standard meter type can be manufactured if the detection equipment is not required.
d) Also includes a converter.
Type I S-3: For 3P
Type I S-1: For 1P

Operating Principles

Apply an AC power supply to the extra power unit to generate DC50V on the output side.
This DC power supply can be used to combine the unit with a DC ammeter with an MΩ scale, making it possible to take measurements and read earth resistance for circuit currents that change depending on the ground status.
The AC side and output side of the extra unit are insulated by a transformer. This means that the DC power supply can be considered separate from the lines, creating the basic circuit shown on the left.
In the circuit diagram on the left, DC50V is being generated by the power unit, the power is connected to the meter in a series where Rs = 0.2 MΩ (scale centering on meter), and a resistance value is being indicated.
When switch S is turned on, the pointer of the meter moves to the maximum, indicating 0MΩ in this case

This means that the maximum current sensitivity value of the inflow current is :

If a grounding accident occurs and the earth resistance is 0.2 MΩ (Re = 0.2 MΩ), the inflow current:

and the center scale point of 0.2 MΩ is indicated.

The relationship between the earth resistance value and the current i is as shown below.

How to Use

Resistance value between LINE, R, S or T and earth is measured between A and B.
In the diagram on the left, the measurement is taken from phases S and T, but any phase can be used.
The diagram on the left shows an example connection between MPV and 11, but the same result will be obtained between MPC and 12 (vertical terminal array).
The zero ohms adjustment volume is a backup device embedded in the center of the power unit. Insulate auxiliary power supply terminals (9) and (10) before checking the zero
ohms adjustment.

A precise meter relay that uses the deflection of the pointer to control the external circuits.
Toyo Keiki manufactures devices with photoelectric-type configurations.

Features of Meter Relay

•  These meter relays possess the various features of a contactless solid state relay.
• The relay circuits and detection relay are integrated into the main body of the meter.
  This reduces labor, potential misconnection and other issues in steps such as connection and installation of the included cells.
• Highly reliable operation.
• Reliable operation even during minute meter input.
• Set point passage-type relay.

Operating Principles of Photoelectric Type

A light source and a receiver are installed on the upper limit and lower limit pointers respectively. The collector current of the photo transistor receiver changes when the foil attached to the movable pointer goes between the light source and the receiver by means of the movable coil input. This change in current is converted to a change in voltage which passes through a comparator circuit and a switching circuit to operate the detection relay.

Wide-angle Meter Relay
Photoelectric-type Circuit Configuration

Operation Mechanism of Contactless Meter Relay

While the standard output signal format of the meter relays is a passing signal retaining type, the following three types are used for the MPV-11.

1. Passing Signal Retaining Type

When the pointer moves past the setting value, the passing signal is retained after signal output. The signal returns to normal after the pointer moves back to the setting value.

2. Passage Type/Instantaneous Type

The same structure as the stop type below, except without the stopper. The output signal returns to normal when the pointer reaches around 8% of the scale length past the setting value.

Precautions for Use

(1) When using a meter relay with L settings (except the wide angle passing signal retaining type), take care not to turn on the power of the meter relay and the meter input at the same time, as the L side signal will be generated continuously until the meter pointer passes the set L pointer.
(2) Avoid using in areas where the meter will be directly exposed to sunlight in the middle of summer, as these are photoelectric-type meter relays.

Wide-angle Meter Relay (Passing Signal Retaining Type)

While 90° displacement meter relays have a shielding plate at the 90° point and can retain the signal by themselves after the pointer passes this, wide-angle meter relays are mechanically unable to do this because the displacement angle (240°) is too large. An electronic storage method is used instead.
As a result, the following issues occur the first time the auxiliary power supply is turned on. Please take this into account when designing circuits.

(1) When the Auxiliary Power Supply is Turned On (L Side Only)
Load relay operation on the L side should be turned on when the meter pointer is a zero and the auxiliary power supply is turned on, but in this case operation does not occur unless the pointer is displaced to around 17mm before the L setting value.
However, this only occurs the first time the pointer passes after turning on the power. After this, operation is turned off when the L setting value is passed and on after returning to normal, and remains on after returning to zero.
This only occurs for the L setting. Normal operation occurs from the start for the H setting.

(2) When the Auxiliary Power Supply is Stopped
If the indicator input and auxiliary power supply of the meter are applied by different circuits, the auxiliary power supply stops when the pointer goes above the H setting value and the H load relay activates. If the pointer continues to indicate the same value, the H load relay returns (turns off) at the same time as the power supply, and usually turns back on when the power is turned on again.
However, if the power is off for 40 seconds or longer, the storage circuit no longer retains the signal, with the result that the previous signal is no longer output when the power is turned on again. If the power is off for 40 seconds or longer, be sure to return the pointer to the zero position by opening or shorting the meter input circuit.
No issue occurs when the power is off for short periods of less than 40 seconds, as the storage circuit remains live.

Remarks

When Using CT
1. Combine the meter with CT and the C-3 model 5A (1A)/10mA current transducer if 100A is exceeded.
2. When circuit voltage of 460V is exceeded at 100A or below, combine the meter with CT and the C-3 model 5A (1A)/10mA current transducer for insulation.
Note: The C-3 model current transducer is a dedicated accessory for the meter. The combined intrinsic error for the meter and the C-3 model current transducer is ±2.5%.

Frequency 
Indicate the frequency when measuring AC outside of commercial frequencies.
(Can be manufactured from approximately 30Hz to 10kHz)

Extended Scale Meter

Meters attached with double, triple or 5-times extended scale to use for measuring the current flow of electric motor-class of starting current can be manufactured.
(In this case, the M-2A model rectifier box is externally connected.)

Scale Calibration : Conducted via sine waves.

Note

1. Multi-scale meters can also be manufactured.
2. We also manufacture R.M.S.-Response models that minimize the impact of waveforms. The model names are SeCF-6, 8, 10 and 12N.
(The C-3 model current transducer and M-2A model rectifier box are externally connected.) (Additional price)
The scale is nonlinear, condensed near zero.
Telemetering
For direct feed type telemetering, you can reduce line loss if the second rated value uses a 1A CT combined with a 1A meter. (The rated value of 5A is 1/25.)
To further reduce loss, use an AC current transducer combined with a DC meter.
(For details on AC current transducers, see the dedicated catalog.)

Remarks

Connection to Series Resistor :
Meters over 750V must be connected with the voltage division type series resistor specied in
the table above as shown in the gure on the right.
Note) M-6 series resistors must be connected to the earth using the G terminal.
The G terminal is only available on the M-6 series resistor.
There is no G terminal on other series resistors because the boxes are made of resin.
Meter Sensitivity

Standard DC voltmeter sensitivity is 1mA (1kΩ/V), but high-sensitivity meters can also be manufactured.
However, the 500V and 600V meters have a sensitivity of 500μA.

Remarks

Instrument Lead Instrument lead is not included
Instrument Lead Resistance :
1. Meters externally attached to shunts are normally adjusted to an instrument lead resistance of 0.05Ω for the specified meter. (Indicate LEAD 0.05Ω on the scale plate)
Note) Use wiring that is equivalent to 0.05Ω for the wiring of the instrument lead.
2. Please specify separate instructions if the instrument lead resistance of the specified meter is to be a value other than 0.05Ω. (Instrument Lead Resistance: Can be manufactured up to 1.5Ω…However, use a meter with both a voltage drop and shunt of 100mV for 1Ω or more.)
3. If the instrument lead resistance is not clearly specified, the meter can be manufactured with a sensitivity adjustment variable resistor (VR).
Note1) The model name of a meter equipped with VR is the same as the normal model name with V appended. E.g. DCF-12NV
2) DCF-5 meters equipped with VR cannot be manufactured.

Connection to Shunt

1. Connect the shunt to the wires on the earth side.

Note

Zero center meters and multiple-scale meters can also be manufactured.
